• DDS - Discovery/Search System v3.4.0 file released: dds_v3.4.0.zip

  Changes in v3.4.0 (released March 23, 2009) -With this release the license has changed from GPL to Educational Community License v1.0. -Implemented REST service API for making repository updates: putCollection, deleteCollection, putRecord, deleteRecord -Added 'key' attribute to the Collection element in the ddsws GetRecord and Search response head element -Added 'maxSearchResultsAllowed' element to ServiceInfo response -Added and updated documentation for stand-alone release. There is now one set of menus that are displayed when deployed at DLESE, another when deployed as a stand-alone application. -Changed repository actions in the Collection Manager UI to be submit forms rather than links. -Added ability to configre which days of the week, not just time of day, to run the indexing cron for both the file system and external (NDR, etc.) data sources -The NDR indexer config now accepts the full NDR API baseURL, not just the host name, when configuring the repository -Removed dependency for dlese_shared context when DDS is deployed as stand-alone application. -Reverted back to dom4j v1.4 from v1.6.1 to be compatible with NDR API parsers -Default Java XSL transform engine is now used, to be compatible when running in Tomcat with fedora. Removed the following explicit System.setProperty call: System.setProperty("javax.xml.transform.TransformerFactory", "com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl"); -Updated dlese_anno to nsdl_dc transform to be compatible with the above change (fixed typo) -Created dist ant targets to build and zip the binary distribution -Fixed issue with putCollection and deleteCollection calls where sometimes a collection would not get updated/deleted properly Changes in v3.3.15 -A geospatial search query can now be conducted in the DDSWS service by supplying the following arguments: geoPredicate, geoBBNorth, geoBBWest, geoBBEast, geoBBSouth, geoClause. Previously, geospatial queries needed to be separately encoded and then supplied as part of the query (q) argument. -Added a 'code' attribute to the error response element in DDSWS 1.1 that indicates the type of error. This makes it possible to determine the reason why a request failed and respond appropriately to users. Error codes include noRecordsMatch, badArgument, badVerb, badQuery, notAuthorized, internalServerError. Note that, while this should not effect consumers of XML response from the service, the structure of the JSON output has changed slightly and my effect clients that use it. -Updated the JSON example client to handle the new error code data format. -If geospatial bounding box footprint extent crosses longitude 180/-180, the indexer now culls the search bounding box to the largest of one side or the other to be compatible with the search algorithm. -In the DDSWS search service, if the query crosses the 180/-180 longitude it is split into two query regions, one on each side, joined by boolean clause. -More robust error checking is now conducted in the indexer to ensure geospatial bounding box coordinates are error free. If a bounding box is non-conformant, it is gracefully dropped from the given record. -Fixed issue in default XML indexing where default field text across elements was sometimes concatinated, combining the first and last tokens of consecutive XML elements -Added a configuration framework for specifying search fields for any XML framework. Standard search fields (id, url, title, description, geospatial bounding box: geoBBNorth, geoBBSouth, geoBBWest, geoBBEast) and custom search fields can be defined in a configuration file for a given XML format. -Added default search fields for all xml formats derived from the xPath to each element and attribute in the XML instance document -fixed issue in DleseCollectionDocReader where the file path for error docs was not escaped, making admin search fail for error totals -fixed issue where the file path for error docs was not escaped, making search fail for error totals -upgraded to lucene v2.4.0 -upgraded to dom4j v1.6.1 -configured indexer to use SnowballAnalyzer for stems fields, which provides improvements over PorterStemmerAnalyzer -Updated the DDSWS documentation with additional/new information on: -Info on the XPath search fields -Info on conducting a geospatial search -Info about service error codes -More clarification about search fields in general -Added documentation about how to configure standard and custom search fields for any XML framework in a DDS repository. Changes in v3.3.14 -Added JSON as an optional output format for the Web services. -Added option to remove namespaces from XML and JSON output. -Added a JavaScript/JSON example page for download. -Added more ncs_collect specific search fields to the indexer. -Added dlese_anno to oai_dc and a few other xml format converters -Updated some documentation pages. Changes in v3.3.13 -Added ncs_collect specific search fields to the indexer. -Updated the DDSWS and other documentation pages and added details about ncs_collect search fields. Changes in v3.3.12 -Fixed indexing 'StaleReaderException' caused by reader/writer lock synchronization Changes in v3.3.11 -Updated the OAI explorer page to allow users to enter and explore different baseURLs -Added display of schema and namespaces in OAI ListMetadataFormats response, configured in web.xml -Created a config option to allow standard OAI-PMH responses from the data provider. By default, only ODL requests are allowed. Still TO-DO: Config for Identify, ListSets and additions for ListMetadataFormats -Fixed bounding box index encoding problem for geospatial searches -Created EL functions in DLESETools to generate bounding box geospatial queries using lat/lon coordinates
