1. Overview of Freemix

Freemix is a social networking site for digital content. Use Freemix to slice, show and rapidly share data with your colleagues and friends. Using Freemix, you can transform basic data to create compelling Web pages which allow the data to be viewed and analyzed in many ways. You can easily allow your content to be viewed in a list or a table, on a map, or in timeline, scatter plot or pie chart views.

Anyone who creates and analyzes data will quickly see the power of Freemix. Those who wish to share data with colleagues or in a group will find Freemix invaluable.

With Freemix you can:

• Add data which exists in comma-separated value (CSV) files, BibTeX, Exhibit JSON, Atom or simple Excel spreadsheet format
• Choose which fields show in the interface
• Change the field labels
• Create "facets" from the data such as list of keywords or tag clouds to enhance discovery
• Enhance the data with outside services and show it in a variety of views
• Preview the interface you make
• Publish the collection to the Recollection interface
• Share the collection with your friends and colleagues

Whether you want to share spreadsheets with scientific findings or lists of artwork or photos in a more Web-friendly way, you can rapidly expose your content using Freemix. If you wish to securely and privately share data with only your family and friends, please contact solutions@zepheira.com, to learn how to create secure and custom solutions based on Freemix.

Freemix makes every attempt to support the following Web browsers: Microsoft Internet Explorer v.7 & 8, Firefox v.3.x, Safari v.3.x and Safari v.4.x. Opera v.9.x, Camino v.1.6.x, Firefox v.2.x mostly work but are not as thoroughly tested and not officially supported. Internet Explorer v.6 does not work with some of the software used by Freemix and so we cannot support it.

For the moment, five types of files can be imported into Freemix: Comma-separated value files (CSV), BibTeX files, Atom news feeds and Exhibit JSON files (UTF-8 or UTF-16 character encoding) are supported formats. Simplistic Excel spreadsheets may also be used, but their proprietary format will not always import into Freemix.

Many users will prefer to upload comma-separated value files that are exported from spreadsheets or databases. Please note that some programs, particularly Microsoft Excel and Access, can produce inconsistent data during CSV export. Such data may need to be cleaned before it can be imported into Freemix.

BibTex files are often used by academics and publishers. They are perfect for publishing bibliographies.

Atom news feeds are published by many Internet services, such as Flikr, FriendFeed and del.icio.us. Using Atom to make Freemixes gives you a new way to display and track your Internet collections.

Exhibit JSON is the data format used by Exhibit. Developers wishing to create custom data feeds for import into Freemix can create Exhibit JSON from databases or other data sources and upload that information to Freemix. Note that support is offered for both UTF-8 and UTF-16 character encoding.

Simplistic Excel spreadsheets may be used to get data into Freemix, but every version of Excel's proprietary format cannot be supported. By "simplistic", we mean that a single worksheet can have contiguous rows and columns that form a rectangle. This "rectangular spreadsheet" can have blank columns to the left and right and an optional title and subtitle at the top, as long as they are in single cells.

Best results will be obtained from data with less than 1,000 records, e.g. spreadsheets with less than 1,000 rows or BibTex files with less than 1,000 citations. Larger amounts of data will result in significant time delays or even a failure to load the data set.

2. Creating a Freemix account

Anyone can sign up for a Freemix account. Creating an account allows you to access all the features of Freemix, create your own personal profile, save the Freemixes you create, and connect with other users and groups who have similar interests.

4. Create A Freemix

Creating a Freemix is quick and easy. You can add data to Freemix using previously created files which exist on your desktop or which are accessible via URL. For files accessible via URL, all data changes made to the source file will be immediately reflected in the Freemix collection as they are saved. Files loaded from the desktop are static. Updates to source files will not be reflected in Freemix collections automatically, but can be updated by creating a new collection from the updated source file as needed.

Data formats currently supported are: Comma-separated value (CSV) files, BibTeX, Exhibit JSON (UTF-8 and UTF-16 character encoding), and Atom. Simplistic Excel spreadsheets work in many cases, but cannot be fully supported due to their proprietary format. For best results, follow the data guidelines supplied in Section 9: Details of Supported Data File Formats.

4.1 Upload Your Data

Files of supported data types may be uploaded from your desktop or from a URL. Currently, data files should not exceed 1000 records, although Freemix may handle more. Files over this size will take significant time to load. Note, databases that contain very large individual records may need to have smaller record count.

To upload a data file to Freemix, start from the "Profile" page. Click the "Upload Data" tab. You will be directed to the "Upload Data" page shown in Figure 4.

Figure 4. Upload Data

4.1.1 Add a File From the Desktop

• Click "Choose File" under the "From a File" section on the left-hand side of the screen.
• Locate and select the file from your hard drive.
• Click "Upload".
• Freemix loads your file into the "Identify" screen to allow you to describe your data.

4.1.2: Add a File From a URL:

• Type the URL into the text box which appears below the words "From a URL" on the right-hand side of the "Upload Data" page.
• Click "Retrieve".
• Freemix loads your file into the "Identify" screen to allow you to describe your data.

4.2 Describe and Publish Your Data

After loading the data, Freemix allows you to review the data fields and modify them to support creation of your final published page. There are three options for modifying the data:

• Choose to hide certain data fields by un-checking the box next to the field
• Rename the data field labels by clicking on the name, changing it and choosing, "rename".
• Reorder the fields using drag and drop.
• Change the data type - "text" is the default type, other choices include:
  • URL - will make the field value a link
  • Image - will wrap it in an image tag, so it'll render as an image in recollection
  • Datetime - use this to enable a field for use in the Timeline feature. Using standard-based date formats will ensure accuracy and be easier integration with other collections. (e.g. 2008-09-30T20:07:55-8:00 )
  • Location- use this to enable a field for use in the Map View feature.
  • lat,long (for Excel and XML MODS)
  • City, State (XML MODS)

The Identify screen (see Figure 5) allows for further description of the data which has been uploaded to Freemix. Fields can be hidden, renamed, and data types changed.

Figure 5. Describe Your Data

4.2.1: Hide a Field

To indicate a field should not be shown in the final view, uncheck the check box next to the data field in the "Enabled" column.

4.2.2: Rename a Field

• Click the text of the field name to be changed in the "Property Label" column. An editable text box appears.
• Edit the text as shown in Figure 6.
• Click "Rename" to rename the field.
• Click "Cancel" to revert to the last saved version of the field name.

Figure 6. Rename a Field

4.2.3: Change a Data Type

Data types are used to drive view features such as the ability to plot data on a map or a timeline. By changing data types, you indicate to Freemix what kind of data it is dealing with so that it can be properly processed. For instance, to plot a data point on a timeline, it must be indicated as "date/time" format. It is advisable to indicate data types up front so that you do not have to back track later if you decide to add a new data-driven view.

• Click "modify" in the "Types" column next to the data field to be updated.
• Add one or more property types for the data field by clicking on the "+" next to the desired type.
• Remove any property types that are not appropriate by clicking "-" next to that type.
• Click "OK" to approve the changes.
• Click "Cancel" to revert to the last saved version of data types.

Repeat this process until all data field types are described as desired.

To View Additional Data Records: The Identify screen displays the first record of the data file that was submitted for upload. You may want to check the other records in your data file to ensure they look as expected.

• Click on the "Next" button at the bottom right corner of the Identify screen. The number of records that was imported is displayed and record number displayed in the current view is indicated (for example "5 of 45").
• Navigate through the records as desired using "Next" and "Previous" buttons.

4.2.4: Publish Your Data

Once you have finished describing your data, you can publish it to the Web. Your data is given a URL and a data profile is created and added to your collections of data.

It is important to note that data published on Freemix is public. Other users who have access to the site will be able to view your data and create their own Freemixes using your data profiles. Because of this, it is important to consider the kinds of data you upload to the site and ensure that you have legal rights to do so.

To publish your data in Freemix:

• Click "2. Publish" in the progress band toward to top of the page to proceed to this step.
• Enter a name for the new data profile in the text box provided.
• Click "Publish".
• The URL for your data profile is shown and you are given the option to proceed and create a new Freemix.

4.3 Details of Supported File Formats

For the moment, five types of files can be imported into Freemix: Comma-separated value files (CSV), BibTeX files, Atom news feeds and Exhibit JSON files (UTF-8 and UTF-16 character encoding) are supported formats. Simplistic Excel spreadsheets may also be used, but their proprietary format will not always import into Freemix.

Many users will prefer to upload comma-separated value files that are exported from spreadsheets or databases. Please note that some programs, particularly Microsoft Excel and Access, can produce poorly formatted data during CSV export. Such data may need to be cleaned before it can be imported into Freemix.

BibTex files are often used by academics and publishers. They are perfect for publishing bibliographies.

Atom news feeds are published by many Internet services, such as Flickr, FriendFeed and Google Reader. Using Atom to make Freemixes gives you a new way to display and track your Internet collections.

Exhibit JSON is the data format used by Exhibit. Developers wishing to create custom data feeds for import into Freemix can create Exhibit JSON from databases or other data sources and upload that information to Freemix.

Simplistic Excel spreadsheets may be used to get data into Freemix, but every version of Excel's proprietary format cannot be supported. By "simplistic", we mean that a single worksheet can have contiguous rows and columns that form a rectangle. This "rectangular spreadsheet" can have blank columns to the left and right and an optional title and subtitle at the top, as long as they are in single cells.

Best results will be obtained from data with less than 1,000 records, e.g. spreadsheets with less than 1,000 rows or BibTex files with less than 1,000 citations. Larger amounts of data will result in significant time delays or even a failure to load the data set.

Troubleshooting Data File Uploads

We're sorry that you've encountered a problem uploading your file. Please use the following troubleshooting tips to try to correct the problem:

For spreadsheets:

• Remove any data that is not in a solid rectangular area. This includes white space, page titles, scattered cells, and additional worksheets.
• Check that your formatting is consistent throughout each column (e.g. column is all in date format, currency format, etc. as appropriate)
• Make sure that data of the same type but in different columns is formatted consistently (e.g. dates in different columns are in the same date format).

For Atom files:

• Remove any extensions from the Atom file. We support most Atom, but we can't guarantee to support all extensions.
• Make sure your Atom validates as XML. Try Feed Validator

For CSV files:

• Look for characters in differing characters sets (especially if you exported the CSV from Microsoft Excel or Access)
• Make sure any dates and times are in consistent formats.
• Make sure the CSV file is in the iso-8859-1 character set.

For Exhibit JSON files:

• Make sure your Exhibit JSON file validates as JSON. Try the validator at http://www.jsonlint.com/
• Make sure your file is in the UTF-8 or UTF-16 character sets.

For BibTeX files:

• Have a look for duplicate entry keys, duplicate field definitions, and missing mandatory fields.
• Try to validate your BibTex with an editor that includes a BibTex validator.

If you have a file that you think should work after troubleshooting please send us your file with some information to help us debug the problem. Send us your file to mailto:feedback@freemix.it with the following information:

• Your computer's operating system name and version.
• The name and version of the application used to create the file.
• Please copy and paste information from the "About" page of the application used to create the file.
• Don't forget the file itself!

4.4 Build Your Freemix From a New Data File

The Build step allows for styling of the final view of the collection by adding Collection title, subtitle, and modifying background colors or theme. In addition, the Build screen provides the ability to add navigation widgets of choice (e.g. facets, tag clouds) as well as relevant views (e.g. maps, timelines). Click "2: Build" in the progress band toward the top of the screen to proceed to this step.

In this step, you are forming the user interface view for your data. This is the section where you can determine how the user can search, narrow results, view timelines and/or maps. You may add several facets or none before leaving this section. Build options are:

• General Look and Feel:
  • Add Title, Subtitle - Give the collection a Title and subtitle.
  • Determine the "theme style" of the interface. There are three to choose from in the Recollection Preview.
• Add a "Facet": Facets provide users with a way to narrow their search. You may create facets that are right, left or above the main section of the interface. There are several types of facets that you may implement:
  • Search box - use this to give you the ability to search any part of a record
  • List - creates a list from a designated field that you can use to narrow your search
  • Tag Cloud - Creates a tag cloud from a designated field that you can use to narrow their search
  • Image - Creates a thumbnail view the the data
  • Logo - Allows you to place a logo available via URL on your Freemix page

4.4.1: Add a Title and Subtitle

Titles and Subtitles will be displayed on your published Freemix page. The Title defaults to the same name as your data file, but this can be modified at any time by following the directions below.

• Click on the words "Click to Edit Title..." or "Click to Edit Subtitle..." near the top left corner of the screen.
• Type the desired text.
• Hitting the "return" or "tab" keys or clicking on any other part of the screen accepts the changes.
• To create additional edits, simply click on the words again and type in changes.

4.4.2: Add Facets

Navigational "facets" can be added to the final collection page to assist collection users in sorting through information within the collection. Facets that can be added are search boxes, list facets, tag clouds and image viewers. To add tools which will allow users to navigate data on the collection page:

• Click on "Add a Facet" in the area of the screen where the navigation tool should be placed. There are three areas which can be selected: top, left or right.
• Select the type of facet that should be added: search, list, cloud, or image.
• Select the property that will drive the navigation for the selected facet. For example, if navigating the collection by state is needed, select the data field that contains state information.
• A placeholder for the selected facet will appear in the appropriate portion of the screen. For convenience, facet type, property name, number of fields containing values, and number of fields missing values are displayed.

Figure 7. Add Facets

4.4.3: Remove Facets

Facets may be removed at any time during the Build process. To remove a facet that has been added during the Build process:

• Click the down arrow which appears at the top right corner of the facet that should be removed.
• Click "Delete".
• The facet will disappear from view.

4.4.6: Set List View Preferences

A list view is added as the default view option. To modify preferences for the list view:

• Make sure that the "List" tab above the data fields list is selected.
• Hide fields that should not be displayed by unchecking the box next to the associated data field.
• To add a title to each record in the list view, click "edit" in the Title bar at the top of the data fields list. Select a data field from the pulldown menu which contains the data to be displayed as a title. Choose the field which contains the data to be displayed as a title. Select "OK' to add the title field.
• Data fields may be reordered by clicking on the field to be moved and dragging it to the desired location.

4.4.7: Set Map View Preferences

Once a map view has been added, preferences must be chosen so that it will display as desired. Pre-requisite: Your file must contain latitude and longitude values in order to use the map feature. Future versions of Recollection may provide lat/long lookup services which will augment the original data file with latitude and longitude automatically and enable mapping.

• Make sure that the "Map" tab above the data fields list is selected.
• Click the radio button in the "Lat,Lng" column next to the field that displays latitude and longitude. This enables values to be plotted on a map.
• If map pins should be displayed in different colors based on a property, click the radio button in the "Color" column to create a map legend.
• Once plotted on a map, each of the pin points can be clicked and additional data displayed in a pop-up box. To hide data fields to be shown in the display, uncheck the box next to the data field to be hidden. To add a title for the pop-up box, click "edit" next to "Title" in the bar at the top of the data fields list. Select a data field from the pulldown menu which contains the data to be displayed as a title. Choose the field which contains the data to be displayed as a title. Select "OK' to add the title field.
• Data fields may be reordered by clicking on the field to be moved and dragging it to the desired location.

4.4.8: Set Scatterplot View Preferences

A scatter plot is a type of display using coordinates to display values for two variables for a set of data. The data is displayed as a collection of points, each having the value of one variable determining the position on the horizontal axis and the value of the other variable determining the position on the vertical axis. To set preferences for a scatterplot view:

• Make sure that the "Scatterplot" tab above the data fields list is selected.
• Choose the data property to represent the X axis
• Choose the data property to represent the Y axis

To add a title for the pop-up box, click "edit" next to "Title" in the bar at the top of the data fields list. Select a data field from the pulldown menu which contains the data to be displayed as a title. Choose the field which contains the data to be displayed as a title. Select "OK' to add the title field.
• Data fields may be reordered by clicking on the field to be moved and dragging it to the desired location.

4.4.9: Set Table View Preferences

Freemix allows you to show your data displayed in table format. To set preferences for a table view:

• Make sure that the "Table" tab above the data fields list is selected.
• If desired, use the radio buttons to indicate the order of the data in the table by selecting "Asc" for ascending order and "Desc" for descending order.
• Choose the data property to represent the Y axis
• To hide data fields to be shown in the display, uncheck the box next to the data field to be hidden.
• Data fields may be reordered by clicking on the field to be moved and dragging it to the desired location.

4.4.10: Set Timeline View Preferences

Once a timeline view has been added, preferences must be chosen so that it will display as desired. Pre-requisite: Your file must contain at least one date field which has been marked as type "date/time" in the Identify step in order to use the timeline feature. You may return to the Identify screen at any time prior to the Publish step to indicate this type if needed.

• Make sure that the "Timeline" tab above the data fields list is selected.
• To indicate the range of time to be plotted for entries, choose the data fields which contain the start and end date for the range using the pulldown menus next to "Range" at the top of the preferences menu. If there is only one date, a point in time (rather than a line indicating a span of time) will be displayed.
• Time scale (e.g. day, week, month, year, etc.) can be indicated using the pulldown band menus. Two different time scales can be chosen using "top band" and "bottom band". Note: It is usually advisable to leave these bands on the default setting of "auto". This allows the application to make a sensible guess as to scale based on the data it was provided. If results do not appear as desired, or there is a need to achieve consistency across a set of collections, the user may adjust the settings.
• To color code items on the timeline based on a property, select the radio button next to that property. Items plotted on the timeline will appear color coded and a legend is added at the bottom of the timeline.
• Once plotted on a timeline, each of the timeline items can be clicked and additional data displayed in a pop-up box. To hide data fields to be shown in the display, uncheck the box next to the data field to be hidden. To add a title for the pop-up box, click "edit" next to "Title" in the bar at the top of the data fields list.

• Click "Delete".
• After confirming the delete prompt, the collection is removed from the Profile. This action cannot be undone.

5. Working With Data Profiles

Each time you upload and describe data, Freemix creates a new data profile. From file's data profile, you can view the data, edit your data descriptions, or delete data. You can also choose to build new Freemixes, as multiple Freemixes can be built off of the same data file to afford you different views of the same data. You can even build a new Freemix off of a another user's data profiles if you wish.

Your data profile list shows all of data files you have uploaded and which are available to work with in Freemix. Your data profile can be viewed from the Profile tab.

5.1 View Data Profile

To view a data profile:

• Locate the data profile in the Data_profile section of the Profile screen.
• Click "View"
• A read-only display of your data properties and descriptions will appear.

5.2 Edit a Data Profile

To edit a data profile:

• Locate the data profile in the Data_profile section of the Profile screen.
• Click "Edit"
• You will be directed to the Identify screen and can edit your data descriptions as needed.

5.3 Create a Freemix from an Existing Data File

Freemix allows for multiple collections or views to be created for the same data set. To create a new collection using an existing data profile:

7. Participating in the Freemix Community

Freemix offers many social and community features to allow you to connect and share data with individuals and groups with similar interests. The community allows you to find friends you know, invite them to connect, create a tribe (interest group), or join an existing tribe.

The social components of Freemix can be accessed from many different parts of the site which are described in more detail below.

7.1 Browse Profiles

To find friends to connect with you can browse the list of profiles that exist on the site. To do this, visit the What Next? page and click on "connect with friends". This directs you to a list of users who are users of the Freemix site. The profiles are listed in date order as they were created. To find out more about each user, click on the link with their user name to see their profile.

Note: If you know the username of the person you want to connect with, you can simply replace your own username with theirs in the URL shown in the address bar. This will take you directly to their profile page.

7.2 Invite Someone to Be Your Friend

Once you've located someone you want to connect with, simply click on the "invite" button on their profile page. You can add a personalized message or use the default message provided. The invitation is sent by email as a connection request. Once approved by the invitee, you are connected. The new connection's gravatar will show up on your profile page under the "Your Friends" section.

7.3 Make Your Tribe

Anyone can start a tribe on Freemix. A tribe is typically a group of people gathered around some common point of interest.

To make your own tribe:

• Visit the Tribes page by clicking on the tab toward the top right corner of the screen.
• Click "Start your own tribe".
• Enter a "slug" in the text box provided. A slug is a a short version of the tribe name consisting only of letters, numbers, underscores and hyphens. It usually does not contain spaces. The slug is used to link the tribe from various places within the site.
• Finish making your tribe by entering a longer name for the tribe as well as a description of its purpose.
• Click "create" to launch your tribe.

Note that as a creator of a tribe, you have the power to delete it at any time. Simply click "Delete this tribe" from on the tribe page you want to remove.

7.4 Join an Existing Tribe

You can find new tribes to join by either browsing the list of tribes shown at the bottom of the tribes page or performing a search. Once you have located the tribe you want to join, click on the link next to its name. This takes you to the tribe page where you may see a list of tribe members and discussions. Tribe members are shown in the top right portion of the screen.

To become a member, click the "join" button. If you decide to leave at a later time, you may click "leave" to exit the group. A list of all the tribes of which you are a member will be displayed on your profile page. These can also be viewed from the My Tribes tab on the Tribes page.

7.5 Start a New Tribe Discussion

To start a new discussion visit the tribe page where you want to kick off the discussion and click on the "more..." link at the bottom left side of the page.

7.6 Send Email to a Friend

Once you are connected to someone within Freemix, you can send them a message at any time by clicking through to their profile page. Here you will find the "Send a message" link. Click on this to compose and send your message.

8. Manage Your Account

You can manage your account settings from the Account page (Figure 12) accessible via the link at the top right corner of every Freemix page. Click on this link if you need to change your email address, associate an OpenID with your account, change your password, or set language or timezone.

Figure 12. Manage Your Account

8.1 Change Your Email Address

To change your email address, click on the "E-Mail Addresses" tab accessible via the Account page. New email addresses can be associated with your account as needed by simply typing them in the box provided and clicking the "add" button.

To delete an email address, click the "remove" link next to the address that is no longer required. Note: You cannot delete your primary email address. If the address marked as primary is no longer needed, add a new email address and once it has been verified, mark this address as primary. You may now delete the old primary email address.

8.2 Associate an OpenID

OpenID is an open, decentralized standard for user authentication and access control, allowing users to log onto many services with the same digital identity. It replaces the common login process that uses a user name and a password, by allowing a user to log in once and gain access to multiple software systems.

You may choose to associate an existing OpenID to your account and remove this association at any time. Note, however, that if you choose to authenticate using OpenID the first time you use Freemix and do not create a user name and password, OpenID login will be your only option.

8.3 Change Password

To change your password, click the change password tab on the Account page. Enter your current password, then your new password twice. Click "change password" to finalize the update.

Lost your password? Click on "Forgot password?" on the login page. If you have provided an email address, you will be emailed a new temporary password. Please log in and change this password to a permanent one ASAP.

8.4 Change Language

Currently Freemix is only supported for the English language. In the future as other languages are supported, you can visit the Language tab on the Account page to select your language of choice for viewing site labels, text and instructions. We are working on Spanish-language support and plan to add other languages in the future.

8.5 Set Timezone

Set your timezone so that receive and sent time for messages is localized to your timezone. To do this, visit the Timezone tab on the Account page, select the proper timezone from the pulldown menu and click "Change my timezone".

8.6 Subscribe to News Feeds

Internet news feeds are formatted text files that are accessible at Web addresses to help you find news information. The most common formats are RSS and Atom. News organizations use news feeds to update people with the latest news information. Freemix uses them to update people regarding the latest data files uploaded and latest Freemixes created. You can track the latest data and Freemixes created across the entire site or by a particular user.

To subscribe to news feeds for a specific Freemix user:
