-----------------------------------------

fixed with revision #1205331
This feature is already used by the org.apache.stanbol.data.site.dbpedia bundle.
Also added support for the Synchronized feature to the Entityhub indexing
utilities.
> Support update functionality for Solr indexes on ManagedSolrServers

> Key: STANBOL-380
> URL: https://issues.apache.org/jira/browse/STANBOL-380
> Project: Stanbol
> Issue Type: Improvement
> Reporter: Rupert Westenthaler
> Assignee: Rupert Westenthaler
>
> Usecases:
> * Stanbol includes a small dbpedia index with 43k entities. Users should be
> able to upgrade this small index with a bigger versions by copying this file
> to the /datafiles folder of Stanbol.
> * Users should be able to update the local index by providing an updated solr
> index archive.
> Implementation
> This feature will use the DataFileProvider infrastructure. The
> DataFileTracker (STANBOL-374) will be used to track if currently used index
> archives are removed or referenced but still missing files become available.
> STANBOL-375 will provide the required functionality to update and remove
> indexes if the user deletes updated the index archives.
> This features will be part of the ManagedSolrServer component.
> Support for Default Datasets
> SolrIndex references ( {name}.solrindex.ref files) will allow to define
> several referenced "Index-Archive" files (separated by ','). This should be
> interpreted as ordered list. Meaning that if an index archive that is
> referenced first should override others. This can be used to refer to an
> archive with a default data set that is automatically overridden as soon as
> the full archive is provided by the user in the DataFiles folder
> Support Synchronized mode
> Users that manages Indexes with local Entities (e.g. Employees, Projects ...)
> might need to update data frequently. The synchronized mode should keep
> tracking source files for indexes via the DataFileTracker even after the
> index was loaded successfully. If a user now delete the Solr index archive
> and replaces it with a new
> version this new data should be also automatically deployed - keep the data
> in sync with the index archive.
> This feature can be acivated/deactivated by the new "Synchronized" swith in
> the SolrIndex references ( {name}.solrindex.ref file).
