Finding the right place at the right price to store burgeoning data just got more economical with lower DuraCloud prices Winchester, MA  Terabytes are the new gigabytes of 2014. Just as you reach into your pocket and discover more change than you ... [More] expected, so it is that information managers are finding terabytes of audio and visual assets and complex research data sets where there used to be mere gigabytes. Like loose change, it’s nice to have extra, but it’s sometimes hard to know where to keep it. As institutional demands for management and storage increase, finding the right place at the right price to store burgeoning data just got more economical with lower DuraCloud prices. Additional terabytes of storage are now available for up to 50% of their original cost. See DuraCloud prices here. DuraCloud is the only managed archiving and preservation service that offers customers multiple cloud storage options–Amazon, Rackspace or SDSC–along with easy drag and drop content upload and download, automatic content health checks and more. DuraCloud ensures your content's long term and low cost accessibility. Learn more about DuraCloud on the web site or get a quote on a DuraCloud subscription plan that meets your needs.

Winchester, MA  The Fedora 4 team is proud to announce the fifth Alpha release of Fedora 4. In the continuing effort to provide rapid access to the quickly growing Fedora 4 feature set, this Alpha release is one of several leading up to the ... [More] feature-complete Fedora 4 Beta release in June. Available from the GitHub release [1] Fedora 4 Alpha 5 "One-Click Run" [2] Fedora 4 Alpha 5 web application [3] Fedora 4 Alpha 5 web application with authorization [4] Fedora 4 Alpha 5 JMS indexer webapp [5] Features Versioning This release enhanced the object and datastream versioning capability [6] in two fundamental ways. Specifically, whereas the creation of new versions was previously supported, this release added the logical corollary capability of rolling back to or reverting [7] to a previous version. Also, the deletion [8] of previous versions is now supported. Triplestore While the internal search index within Fedora 4 natively supports the ability to reindex on startup, the recommended pattern [9] for exposing a search experience to repository users did not support the ability to reindex the external Solr or triplestore indices prior to this release. This release introduced an HTTP endpoint [10] for triggering the reindex of external indices for: the entire repository a tree of resources within the repository, or a single repository resource Beyond reindexing, this release also demonstrated the configuration [11] where there are more than one Fedora 4 repositories all feeding events into a single external triplestore. Linked data In the on-going effort to expose repository resources in a standardized, linked-data friendly manner, Fedora 4 continues to keep in step with the maturing Linked Data Platform (LDP) draft specification [12]. Support for appropriate HTTP request headers which allow the user to indicate a preference for the comprehensiveness of triples found in responses was added. Likewise, appropriate HTTP response headers were added that specify paging [13] information and relationships between parent and child resources in an LDP fashion. Performance Tests were performed this release focused on the determination of whether there is an impact on object creation speeds with the increase in the number of child resources (object or datastream) under a single parent resource. These tests were run with multiple backend storage configurations to additionally assess what, if any, factor the storage backend plays into performance trends. Thirty thousand objects (first with 1 KB datastreams, then with 2 MB datastreams) were created at the top level of the repository and individually timed using the following backends: LevelDB RAM File Although a slight up-tick in per object slowdown was indicated during the 2-MB tests, the trend was not absolutely conclusive. Further tests will be repeated with a greater number of objects. The test results can be found on the wiki [14]. Test Coverage Having a comprehensive suite of unit and integration tests affords the Fedora 4 code-base with greater resilience to rippling bugs, demonstrations of expected usage patterns of the APIs and components, as well as enables architectural refactoring to occur with less risk. A focus of this release was to increase our test coverage [15]. The following are the code coverage statistics at the end of this release. Unit tests: 73.1% Integration tests: 71.7% Overall coverage: 86.0% Housekeeping Several feature enhancements and bugs were addressed during this release. Bug fixes and application polishing included: Added resource locking [16] for concurrent requests on same resource(s) Locking is available at single node and hierarchy tree levels Enhanced pluggability of external/internal identifier mappings Created a utility [17] for uploading a sample dataset to a running Fedora 4 repository Updated jms-indexer-pluggable integration tests to deploy Fedora webapp in addition to triplestore and indexer webapp Enhanced REST-API to return timestamp when creating objects and datastreams Improved HTTP caching headers Corrected multiple HTTP response codes Fixed authorization bug which prevented users with both reader and writer roles from reading a resource Fixed benchtool bug which prevented an equal number of HTTP client threads from being created to support the "num threads" option References [1]  https://github.com/futures/fcrepo4/releases/tag/fcrepo-4.0.0-alpha-5 [2]  https://github.com/futures/fcrepo4/releases/download/fcrepo-4.0.0-alpha-5/fcrepo-webapp-4.0.0-alpha-5-jetty-console.war [3]  https://github.com/futures/fcrepo4/releases/download/fcrepo-4.0.0-alpha-5/fcrepo-webapp-4.0.0-alpha-5.war [4]  https://github.com/futures/fcrepo4/releases/download/fcrepo-4.0.0-alpha-5/fcrepo-webapp-4.0.0-alpha-5-auth.war [5]  https://github.com/futures/fcrepo-jms-indexer-pluggable/releases/download/fcrepo-jms-indexer-pluggable-4.0.0-alpha-5/fcrepo-jms-indexer-webapp-4.0.0-alpha-5.war [6]  https://wiki.duraspace.org/display/FF/Versioning [7]  https://wiki.duraspace.org/display/FF/RESTful+HTTP+API+-+Versioning#RESTfulHTTPAPI-Versioning-revert [8]  https://wiki.duraspace.org/display/FF/RESTful+HTTP+API+-+Versioning#RESTfulHTTPAPI-Versioning-delete [9]  https://wiki.duraspace.org/display/FF/External+Triplestore [10] https://wiki.duraspace.org/display/FF/Indexer+Configuration#IndexerConfiguration-reindex [11] https://wiki.duraspace.org/display/FF/Indexer+Configuration#IndexerConfiguration-multi [12] http://www.w3.org/TR/2014/WD-ldp-20140311/ [13] https://dvcs.w3.org/hg/ldpwg/raw-file/default/ldp-paging.html [14] https://wiki.duraspace.org/display/FF/Flat+Hierarchies+Testing [15] http://sonar.fcrepo.org/dashboard/index/1 [16] https://wiki.duraspace.org/display/FF/Locking [17] https://github.com/futures/fcrepo-sample-dataset [Less]

From Bram Luyten, @mire Belgium, Heverlee  @mire is proud to announce the first public beta release for Mirage 2. Backed by an enthusiastic community of early adopters, this release represents an important milestone in the development of the theme. ... [More] Mirage 2 offers a new user experience for the DSpace XMLUI. The theme is built on modern web technologies including Bootstrap, SASS/Compass and Grunt. The result is a fresh look, improved support for mobile and tablet devices and a range of optimizations behind the scenes. The customization potential that comes with Mirage 2 is illustrated below. On the left you can see what Mirage 2 looks like when it almost exclusively relies on standard Bootstrap CSS definitions. The screenshot on the right shows how Mirage 2 can be customized. In this particular example, the colour scheme was aligned with the traditional Mirage look. The current Mirage 2 release status is beta. The theme has yet to be finalized and contributed prior to becoming part of the official DSpace code distribution. The current interface of the World Bank Open Knowledge Repository served as the basis of Mirage 2. Several members of the Mirage 2 early adopter community are preparing their own production roll-outs of Mirage 2 based interfaces. Download Mirage 2 Beta 1 [Less]
