Calais Integration for Alfresco / Geo-Tagging / FlexSpaces part 2

Filed under: AIR,Alfresco,Flex,FlexSpaces,OpenCalais,Semantic Web — admin @ 00:25

FlexSpaces Geo-Tagging

Here is a screencam video of FlexSpaces 0.8 (which is ready for release). This new screencam shows auto-tagging, semi-automatic tag suggesting,  multiple semantic tag clouds, and automatic geo-location tagging (displayed on a Google map). It uses the Calais Integration  forge project for Alfresco and the Open Calais service.

This map, uses the Google Map Flash API (Flex), displays markers where there is location info provided in the semantic tags  (location info from Calais via the Calais integration).  When you click on a marker, it works just like a tag cloud,  and drives search results.

(Note: the previous part 1 post  also showed showed auto-tagging and multiple semantic tag clouds in FlexSpaces).

FlexSpaces with the semantic tagging / Calais features can be run in 4 different ways:

  • FlexSpaces+AIR with Adobe AIR (1.1, 1.5)
  • FlexSpaces+Browser in FireFox, IE, Chrome browsers (with Flash 9.x, 10.x)
  • FlexSpaces site page components inside Alfresco Share
  • FlexSpaces views as portlets in a portal (such as Liferay, JBoss, etc.)

FlexSpaces supports Alfresco Enterprise/Labs 2.x/3.x, Adobe LiveCycle Content Services ES (currently have just been testing FlexSpaces 0.8 and the semantic / Calais features with Alfresco Enterprise 3.0).

FlexSpaces 0.8 will have the following new Flex based components (and Cairngorm non ui apis): node semantic tag properties editor, auto-tag action, tag suggestion dialog, semantic tag cloud, semantic tag category tree, general Google map, semantic geo-tag map.

Liferay + FlexSpaces + Alfresco

Filed under: Alfresco,Flex,Flex Portlets,FlexSpaces,Liferay,OpenCalais,Portals / Portlets — admin @ 18:09

HOW TO: FlexSpaces in Liferay IFrame portlet

liferay iframe flexspaces

screencam video demo

I just tried a quick test of running FlexSpaces+Browser in a Liferay IFrame portlet. It worked! All features of flexspaces worked:

  • Doc library, search, tasks, wcm views
  • Drag/drop of files between dual panes, internal cut/copy/paste between spaces
  • File upload, file download, file viewing, preview, play video
  • Checkin, checkout, edit, cancel checkout, update, make versionable, version history panel
  • Icon, thumbnail, grid list, cover flow view modes
  • Search, advanced search, tag cloud, category navigation
  • Create space, properties edit, tags/categories edit
  • Make pdf, make flash, start workflow
  • Coming flexspaces 0.8 features with Calais integraion (auto-tag, manual semantic tag properties edit, multiple semantic tag clouds)

Issues noticed: works best when portlet maximized, when not, doesn’t use full portlet area, when switching portlet between regular and max size looses login, liferay dialog not always on top of iframe/flash. Things might work better with the Liferay Flash portlet.

(Update 8/16/09: Added short term state save/restore in SharedObject of ticket/doclibPath/tabIndex in FlexSpaces. Now works much better (don’t loose login, view state when resize portlet. Used Liferay Flash portlet instead of IFrame portlet. Also Liferay dialogs z order was fine. Also would work with flexspaces webapp installed in either Liferay tomcat or in Alfresco tomcat (just different Flash portlet swf url config) )

Didn’t try more integrated approaches yet:
Webscripts as Liferay portlets on ecmarchitect.com
Full Integration of Liferay 5.1.2, Alfresco 3.0 E, SSO, LDAP
Use Liferay Flash portlet instead of iframe portlet

Config used: Alfresco enterprise 3.0 in one tomcat, Liferay 5.1.2 in another tomcat, windows vista

How to:
0. Install Alfresco enterprise or labs
1. Normal install of flexspaces+browser flexspaces dir in alfresco tomcat webapps area, flexspaces+browser 0.7
2. Flexspaces webscripts installed in alfresco, flexspaces 0.7 webscripts
3. Install separate liferay + tomcat bundle from liferay.com
4. I changed all the ports in liferay tomcat conf/server.xml to start with 9 instead of 8 (9080, etc.) to not conflict with tomcat running alfresco
4. Start alfresco tomcat
5. Start liferay tomcat and login test@liferay.com (password: test)
6. With liferay “Add application” add a IFrame portlet from the Sample category
7. Configure the portlet to have the source url: http://localhost:8080/flexspaces/FlexSpaces.html
8. Title of portlet can be changed to “FlexSpaces” by clicking on “IFrame” text in the title and editing
9. If portlets of the FlexSpaces individual views instead of all 4 views in one portlet, (or 2 views only in one portal, etc.) the srcUrl args doclib=true&search=true&tasks=false&wcm=false to FlexSpaces.swf can be used like in the flexspaces 0.7 page site components for share (See FlexSpaces Share integration blog post with screenshots)

Calais Integration / Semantics for Alfresco – sneak peak part 1

Filed under: AIR,Alfresco,Flex,FlexSpaces,OpenCalais,Semantic Web — admin @ 23:17

Auto-tagging in FlexSpaces with Calais Integration for Alfresco

Here is a sneak peak video of  semantic auto-tagging and multiple semantic tag clouds coming in the next release of FlexSpaces+AIR / FlexSpaces+Browser. This uses the  Calais Integration  Alexander and  I have been working on, the Open Calais service, and Alfresco.  The Calais integration auto-tag action can also be used from the “run action” UI in the Alfresco web client (now called Explorer).

Things in the works: Flex UI for tag suggestions, storing URIs in the integration for future linked data use, storing geo-location info from Calais 3.1, and map UI to display geo-location points to filter search results.

The Calais integration amps including web scripts are in the Calais Integration forge project. Note we may use the Semantics for Alfresco merged project for certain pieces in the future. A google code project, semantics4alfresco has also been reserved.   Current FlexSpaces downloads are in the FlexSpaces forge project. Its svn is in the flexspaces google code project.

FlexSpaces Thumbnails/CoverFlow on Alfresco 2.x and LiveCycle CS ES

Filed under: AIR,Alfresco,DAM,Flex,FlexSpaces,LiveCycle — admin @ 21:05

HOW TO: Add support for Thumbnails and CoverFlow in FlexSpaces on Alfresco 2.x and  Adobe LiveCycle Content Services ES using the Thumbnails project from the Alfresco Forge

FlexSpaces show thumbnails LC CS

DocLib Icon view with Show Thumbnails checked (modified FlexSpacesAir 0.7 running on LC CS with Thumbnails 0.5)
(these would look better with larger image files rather than just icon files)

FlexSpaces CoverFlow on LC CS

DocLib CoverFlow view (modified FlexSpacesAir 0.7 running on LC CS with Thumbnails 0.5)

Currently FlexSpaces+AIR 0.7 and FlexSpaces+Browser 0.7 uses the thumbnail service added to Alfresco in 3.0  for thumbnails in its main icon view and in its coverflow view. The “View / Show Thumbnails” menu turns showing them on.  These views are support int the DocLib view, search results, tasks attachments, and in the WCM view.  If the version is less than 3.0 these features are disabled (LiveCycle Content Services is seen by the code as 2.1).   (Note currently creating is thumbnails on upload is disabled FlexSpaces in UploadFilesDelegate.as until I can get this to work better). FlexSpaces will show thumbnails created on upload in Share (did not see any action in the newly named Explorer JSF web client 3.0 for thumb-nailing).

I added 2.x thumbnails sample code to flexspaces google code that make use of the Thumbnails 0.5 project in the Alfresco Forge.  Swap in the 4 modified flex files into the 0.7 FlexSpaces source or FlexSpaces part of the FlexSpacesAir source and rebuild the flex builder project(s). (See the readme there).  There is also a modification to the folderlist web script that you need to update the version of in /Company Home/ Data Dictionary / Web Scripts Extensions / integratedsemantics / folderlist.

Then install the Thumbnails 0.5. Its readme has instructions for installing on Alfresco 2.x.  My readme has some additional install notes for the Thumbnails 0.5 project when installing it on LiveCycle Content Services (LC CS). Also if you want the modifications the thumbnails project did to the Alfresco jsp files you would have to manually merge in the changes to the LC CS contentspace versions of the files (don’t over-write the contentspace jsp files) Since I was just trying to get FlexSpaces work, I skipped this step. You will still have the “Create thumbnails of the item” action available in the contentspace app even if you skip merging the jsps.

On LC CS, you will get some extra authentication dialogs initially when viewing thumbnails.  There is a Catch-22 of LC CS only having a saml “ticket” http header and not “alf_ticket” url arg that regular Alfresco has, coupled with the restrictions on the use of http headers with various Flex/Flash apis (HTTPService api, FileReference upload/download, and viewing with URLRequest navigateToURL). (For HTTPService used flex proxy as a workaround,  FileReference upload/download and navigateToURL still looking for answers )

Note:  FlexSpaces with LiveCycle CS on non localhost:  for now, with the built 0.7 FlexSpaces / FlexSpacesAir will only work when setup on run with LC CS on a localhost test system.   For instructions on how to rebuild it and configure for non local host config see this forum topic.

FlexSpaces 0.7 released

Filed under: AIR,Alfresco,Flex,FlexSpaces,LiveCycle — admin @ 23:10

FlexSpaces 0.7 released

http://forge.alfresco.com/projects/flexspaces/

1. UI strings in resources, Spanish translation (thanks Nuno Barrocas / OKHA Networks), German translation (thanks May Computer), Japanese translation (thanks Tetsuya Suga). (Flexspaces currently only built with English set of resource bundles. source code has all four languages)

2. The locale specific dir for a set of menu xml files to load can be configured (without recompile) by setting default-locale in alfresco-config.xml

3. Added paging support in folder views, search results

4. Added play video support (only avail from context menu, which is always enabled) will launch video in a new tab view with play, stop, pause buttons

5. Added support for Adobe LiveCycle Content Services ES

6. Added version history panel in doclib view (no wcm support) which shows versions of selected doc (if made versionable). View / Version History menu toggle panel on/off

7. tree fixes (select by path not name), refresh when add or delete folder

8. friendlier error msg dialog (stack details collapsed down), Friendlier login error message.

9. Although mainly support flash 9.x player, did some testing with flash 10 player. Only issue: edit does checkout + download with flash 9.x player. With flash 10.x player, edit will only do the checkout. Can still do the download as a separate step with flash 10.x player.

10. Tested with released version of Alfresco Enterprise 3.0

11. FlexSpacesAir has added browser tab running Share (can also be used for running other web page). Previously this feature was a separate experimental download
