2013-04-16 Konstantina Bereta updated license and author informationtemporals
2013-04-16 Konstantina Bereta added a test on the UC case temporarily before moving the temporal tests to the test suitetemporals
2013-04-16 Konstantina Bereta fixed bug that occurs when storing periods having "UC" as ending point. That was supported in initial versions but it got probably messed up in later updates. Going to add tests so that this will not happen again :)temporals
2013-04-15 Babis Nikolaou fixes bug #41. Now, TransTableManager.getTable() always calls TripleTableManager.flushManager(), but flushing is done only when the underlying connection is a MonetDB one. For this it was needed to add a dependency to generaldb/pom.xml to the jdbc implementation of MonetDB. For some reason, a dependency to the jdbc implementation of PostgreSQL was already there as a dependency.
2013-04-15 Babis Nikolaou moved RDFi related constants to RDFi vocabulary class

2013-04-06 Kallirroi Dogani changed StrabonEndpoint to SPARQLEndpoint, added SpatialEndpoint to support KML format for all spatial endpoints (Virtuoso, Parliament, Strabon), added tests for SpatialEndpoint, tests for SPARQLEndpoint with Parliament and Virtuoso. Tests need to be added for Virtuoso endpoint to test which formats are not supported
2013-04-06 Babis Nikolaou updated README
2013-04-06 Babis Nikolaou when inferring rdf:type for Simple Features, infer also the rdf:type between the GeoSPARQL geo:Geometry and geo:SpatialObject classes

2013-04-05 Babis Nikolaou merge
2013-04-05 Babis Nikolaou tidy up GeosparqlRDFHandlerBase to reference GeoConstants. Updated GeoSPARQL URIs. Removed derivation of property geo:hasGeometry from property geo:hasDefaultGeometry (is not a requirement of GeoSPARQL). Derive "object type SpatialObject" when seeing "subject hasDefaultGeometry object". Put inferences for geo:hasDefaultGeometry as an "else if" part to the inferences from geo:hasGeometry so as not to infer the same triples when both properties are present
2013-04-05 Stella Giannakopoulou used ogcgeoconstants when parsing strdf:distance
2013-04-05 Stella Giannakopoulou added check of the unit of measure that given in strdf:distance.
2013-04-05 Babis Nikolaou added OGCConstants. Currently, it contains only units of measure. Also, made endpoint publicize the URIs of the supported units.

2013-03-28 Konstantina Bereta merge with defaulttemporals
2013-03-29 Babis Nikolaou added SPARQLEndpoint that implements Endpoint<TupleQueryResultsFormat>. This class corresponds to the endpoint clients for SPARQL endpoints like Parliament, Virtuoso, etc.
2013-03-29 Babis Nikolaou removed unneeded methods that are already provided by HTTPClient from SpatialEndpoint
2013-03-29 Babis Nikolaou added an Endpoint interface moving all methods of SpatialEndpoint interface to it and used generics for the RDF format. Now SpatialEndpoint is an abstract class implementing the Endpoint interface instantiating the RDF format template with the stSPARQLQueryResultsFormat class. Replaced SpatialEndpointImpl by HTTPClient which undertakes the initialization of HttpClient which then can be used for making HTTP connections.
2013-03-28 Babis Nikolaou changed StrabonEndpoint interface in strabon-endpoint-client to accommodate the case of storing RDF data in named graphs (addresses bug #28)

2013-03-25 Babis Nikolaou commented handling of MultiGeometry case that I assume was using when we were stylying the KML output and now was causing an OutOfBound exception for empty geometries (i.e., MULTIGEOMETRY EMPTY)
2013-03-25 Babis Nikolaou default CRS for GeoSPARQL geometries should be http://www.opengis.net/def/crs/OGC/1.3/CRS84 (or EPSG:3857 -- not very sure for this srid though)

2013-03-23 Babis Nikolaou now isWKTDatatype checks also the wktLiteral datatype

2013-03-20 Babis Nikolaou added --force-delete as an option to *query* command in strabon script. It should be modified to go as a flag to the strabon script so as to be universal for all strabon commands (store, describe, etc.), but this needs some work in files StoreOp, DescribeOp, etc. in order to accept another boolean argument
