Hi all This provides an higher level overview about the work on STANBOL-353, STANBOL-374, STANBOL-375, STANBOL-376, STANBOL-377 and STANBOL-380. People that want/need to know the details please have a look at the listed Issues and the commit statements of the linked commits.
Managed- and Referenced Solr Server ============================ Stanbol supports now two ways of running Solr servers (CoreContainer) within the same JVM: 1. ManagedSolrServer: Allows to create/update/activate/deactivate and remove Solr indexes (SolrCore). 2. ReferencedSolrServer: Allows to init a Solr server for a directory on the local file system. In both cases the CoreContainer and SolrCore instances are registered as OSGI Services with a set of Metadata. Therefore other component can use the Whiteboard Pattern to work with Solr servers and indexes. This possibility is already internally used to publish SolrServers on the StanbolRESTful interface. Both the Referenced- and the ManagedSolrServer do use the same set of properties when registering CoreContainer and SolrCores. For the details how to use this new Services see the main documentation file for the org.apache.stanbol.commons.solr artifacts [1]. DBpedia bundle, Default data and upgrade to a full index. ========================================= The dbpedia.defaultdata bundle was replaced by a dbpedia bundle. Upgrading to a full dbpedia index does no longer require to first remove the dbpedia.defaultdata bundle and than install an other dbpedia bundle (e.g. the one created by the indexing tool). Now to upgrade to an bigger dbpedia index only requires users to copy the "dbpedia.solrindex.zip" file to the "/datafiles" folder of your Stanbol installation. The file will be detected and the upgrade to the bigger index will start immediately. During the upgrade queries will use the old index. After the upgrade is complete the "dbpedia.solrindex.zip" can be safely deleted from the "/datafiles" directory. To upgrade from one full index to an other one needs to 1. delete any existing "dbpedia.solrindex.zip" from the "/datafiles" folder. 2. stop the dbpedia bundle 3. copy the new "dbpedia.solrindex.zip" to the "/datafiles" folder 4. start the dbpedia bundle. If step three is skipped the dbpedia index will be reinitialized based on the default index including 43k entities. Full DBPedia indexes can be downloaded from [2] or created by using the "/entityhub/indexing/dbpedia" indexing utility. This functionality uses the ability to specify multiple "Index-Archives" in Solr-Index-Archive-Reference files.
