Working hard over the course of several months, we were able to accomplish both of our goals. The MST is now processing records at a speed of 1.2M records/hr with no degradation on a set of 6M records on a less than optimal server (1.5GHz cpu). In this talk, I will detail the specifics of the strategies we used to accomplish this major speed enhancement (such as a shift from Apache SOLR to a hybrid SOLR/MySQL approach). In regards to our second goal, third party developers can now download an MST development environment, write a few lines of code, and package their service for deployment into the MST. Third party developers need not concern themselves with the details of the internal MST implementation. In this talk, I will also walk through [http://code.google.com/p/xcmetadataservicestoolkit/wiki/HowToImplementService the steps] required to write a service for the MST.
== Free my DSpace Data! How to get your data out of DSpace 1.7 and restore your content after a disaster. ==
* Tim Donohue, DuraSpace, tdonohue at duraspace dot org
For a while, [http://www.dspace.org DSpace] has provided many means to get content into the system (or create new content in the system), e.g. basic ingest packages, user interfaces, SWORD. However, getting your content out of DSpace, especially for backups or migrations has often been problematic. In the past, although individual Items could be exported in standard formats, entire Collections or Communities (and the relationships between them) could not be as easily exported.
DSpace 1.7.0 provides a new [https://wiki.duraspace.org/display/DSDOC/AipBackupRestore AIP Backup & Restore feature] which allows DSpace to export '''all''' of its contents (Communities, Collections, Items, Groups, People, Permissions, and relationships between all objects) into a series of METS-based Archival Information Packages (AIPs). As these AIPs are just zip files, they can be backed up using your normal backup practices (e.g. to tape, hard-drive, or even to the cloud via a service like DuraCloud). As these AIPs fully describe your DSpace contents, they can be used to restore your entire DSpace after a local server crash or larger disaster.
These AIPs use standard library metadata formats like MODS, PREMIS and METSRights (along with a few DSpace-specific ones where a "standard format" doesn't yet exist) to describe all the content housed in your DSpace installation. This comes in handy, should you ever decide to migrate some or all of your contents to another DSpace instance or another system altogether.
This talk will describe this new DSpace AIP Backup & Restore feature, provide hints/tips on how it can be used to backup/restore/migrate data. Time permitting, I can also touch on the DSpace Roadmap and other ideas/plans to "free your DSpace data".
