Visible changes since 1.4.5 (Version 1.4.6 was an internal release):

• Meandre server can now load flows from the network and then be restarted and run offline.

• Improvements to the Meandre Administrative Interface for user accounts.

• Allow specification of the port when running a flow from the ZigZag console.

• Performance improvement on component installation by using MD5 checksums to check whether a particular resource already exist on the meandre server.

• When regenerating, downloading jar files is skipped if they already exist on the meandre server.

• Bug fixes.

Last night, I created a movie that walks through the process of installing the SEASR/Meandre tools and shows how to run the tools. You can check out the movie at http://repository.seasr.org/Movies/SEASR_Install_and_Run.m4v. If you listen closely you might even hear my puppy squeak a toy.

A new version (0.3.5) of the SEASR Analytics for Zotero Firefox plugin has been released. The new version adds support for Zotero 1.0.* – 2.0b5 and Firefox 2.0 – 3.5.*. A new set of flows (applications) are available, including: Flesch-Kincaid Readability Test, Tag Cloud Viewer, Date Entities to Simile Timeline, HITS Summarizer, and Author Centrality Analysis.

Our user community wanted a different naming strategy, so that one could tell what items were analyzed. If a single item is selected, then the results item maintains the same name as the item. If multiple items are selected, then the results item uses the collection name followed by the number of items selected. In both cases, the name of the service that is executed is provided in the “Creator” attribute. The selected items are also added to the “Related Items” section – a problem with populating these items was also fixed.

We made several changes to improve configuration file specification. One change includes the ability to specify a configuration file in XML format (json support still exists) with additional error messages to indicate problems with parsing your custom configuration file. This configuration file may exist on your local machine and you can use a file browser to find the local file.

The new release can be downloaded at https://addons.mozilla.org/en-US/firefox/addon/10020.
