2014-09-24 Babis Nikolaou updated ChangeLog
2014-09-23 Babis Nikolaou corrected tests that were expecting a WKT in 4326 to contain also the URI of the CRS; we do not include this anymore, if the CRS is the default for that datatype
2014-09-23 Babis Nikolaou corrected another test that was expecting a WKT in 4326 to contain also the URI of the CRS; we do not include this anymore, if the CRS is the default for that datatype
2014-09-23 Babis Nikolaou it turns out that there is no simple way of having the datatype of a constant geometry available in the query builder, thus it is not easy for geof:getSRID to determine the correct datatype and return the appropriate URI for the CRS, when that has SRID 4326. Therefore, we choose to always return CRS84, even for strdf:WKT arguments. Notice, that when geof:getSRID is called evaluated in Java, we have such information available and we can return the correct result. However, we chose in changeset 1420:37792dd7041b to always push the evaluation of all spatial functions in the database. The respective tests have been updated as well.
2014-09-23 Babis Nikolaou added log4j.properties to endpoint-client; corrected test that using geof:getSRID() with a strdf:transform function with an input a geo:wktLiteral constant; in such a case we cannot return CRS84 simply because strdf:transform creates strdf:WKT datatypes for which the default CRS is EPSG:4326
2014-09-22 Babis Nikolaou CORRECT commit message: I de-activated evaluation of grounded expressions in SELECT queries in Java (see the respective #72 the reason I did so)
2014-09-22 Babis Nikolaou fixed a test that was using strdf:distance in ORDER BY clause with two arguments (expecting three arguments always) and de-activated evaluation of grounded expressions in SELECT queries in Java (see the respective #72 the reason I did so)
2014-09-22 Babis Nikolaou more type checking in extension functions in SELECT clause; added also some FIXME and TODO notes
2014-09-22 Babis Nikolaou type checking in extension functions in SELECT clause
2014-09-22 Babis Nikolaou log an info message that we do not support calculation in meters in java
2014-09-22 Babis Nikolaou refixed bug #69
2014-09-22 Babis Nikolaou fixed bug that would cause a class cast exception for grounded expressions with function nesting in the SELECT clause
2014-09-22 Babis Nikolaou buffer in meters in SELECT clauses containing only constants is not supported yet (TODO), but we log a corresponding message and we do the computation in degrees :)
2014-09-22 Babis Nikolaou corrected some tests that were expecting the default SRID (4326) for WKT literals; from now, we do not include such URI, since this is the default and is assumed
2014-09-22 Babis Nikolaou This is a merge commit that addresses the following issues:
2014-09-21 Babis Nikolaou support also geof:convexHull in grounded expressions evaluated in the SELECT clause
2014-09-21 Babis Nikolaou now StrabonPolyhedron carries information about the datatype of the underlying geometry, so as to be consistent with the presentation of results
2014-09-21 Babis Nikolaou corrected output for test that was checking computation of boundary; now that grounded expressions are evaluated using JTS, the boundary of the polygon [Polygon((0 0, 1 0, 1 1, 0 1, 0 0))] is not a Linestring any more as PostGIS was computing (in the wrong way), but LinearRing!
2014-09-21 Babis Nikolaou reverting back to dbpedia.org/sparql for testing endpoint-client on virtuoso
2014-09-21 Babis Nikolaou revert the behaviour of considering EPSG:4326 as lat/long in order to be in line with PostGIS; this is because PostGIS defines several of their functions, like ST_Buffer(Geometry, meters) on SRID 4326. Therefore, if we change this semantics, we would get 4326 lat/long and that would be chaotic
2014-09-21 Babis Nikolaou corrected a test output for getSRID that was set to returning integers (84000) instead of URIs
2014-09-21 Babis Nikolaou a lot of refactoring and cleaning in GeneralDBEvaluation.evaluate(FunctionCall, BindingSet) + support of grounded ST_Centroid in SELECT (ST_MakeLine is still missing)
2014-09-20 Babis Nikolaou Fixed bug #72. The same bug applies to other functions apart from these that return the SRID, such as all the property functions, postgis functions, etc.
2014-09-20 Babis Nikolaou fixes bug #69: better error handling
2014-09-19 Babis Nikolaou added another test for geof:getSRID (see bug #32) that looks in geometries stored in the database
2014-09-19 Babis Nikolaou added another test for geof:getSRID (see bug #32)
2014-09-19 Babis Nikolaou geof:geoSRID was returning the default SRID when argument was not a value from the database; now it returns the appropriate SRID
2014-09-19 Babis Nikolaou Fixes bug #32: implements geof:getSRID properly (now returns the URI of the corresponding SRID of the given geometry)
2014-09-19 Babis Nikolaou changed also MonetDB createGeoValue() for bug #71
2014-09-19 Babis Nikolaou Fixed bug #71
2014-09-18 Babis Nikolaou some cleaning up
2014-09-18 Babis Nikolaou when creating new WKT values in PostGISBindingIteration.createGeoValue(), use the default datatype for WKT (specified in GeoConstants.default_WKT_datatype) and not strdf:WKT
2014-09-18 Babis Nikolaou had forgotten to create typed literals in TSV writer
2014-09-18 Babis Nikolaou correctly identify CRS URIs when present in the select clause in functions like strdf:transform
2014-09-18 Babis Nikolaou removed EPSG:4326 URI from the bounding box of the zoomed map in query.jsp
2014-09-18 Babis Nikolaou corrected endpoint-client/pom.xml to point to the correct main class, so as it can be invoked from the command line
2014-09-17 Babis Nikolaou changed the URL for the DBpedia endpoint in the corresponding test
2014-09-17 Babis Nikolaou configured the output of some tests
2014-09-17 Babis Nikolaou properly construct stRDF WKT literals (CRS URI should not be placed into <> characters); greek characters in the endpoint-client where not encoded appropriately when run from the console (Unit Testin); endpoint-client was encoding the query based on the return value of "Charset.defaultCharset()". We change excplicitly to UTF-8
2014-09-17 Babis Nikolaou moved AbstractWKT.getURI_forSRID() to WKTHelper and added there also creator methods for stRDF and GeoSPARQL WKT literals
2014-09-17 Babis Nikolaou revert databases.properties (committed by mistake)
2014-09-17 Babis Nikolaou moved AbstractWKT.getURI_forSRID() to WKTHelper and added there also creator methods for stRDF and GeoSPARQL WKT literals
2014-09-17 Babis Nikolaou tests in endpoint-client were not using any assertions
2014-09-17 Babis Nikolaou changes in the URLs of publicly accessible endpoints that are used for testing the endpoint-client
2014-09-17 Babis Nikolaou missed a place that used hardcoded EPSG URIs
2014-09-17 Babis Nikolaou added method AbstractWKT.getURI_forSRID(int srid) that returns a URI for the given srid or the empty string; Whoever created such URIs manually, now creates them using this method
2014-09-17 Babis Nikolaou added configurable statement in log4j.properties for debugging queries in PostGIS
2014-09-17 Babis Nikolaou changed default SRID of PostGIS to 84000 (CRS84); changed/updated default CRSs for strdf:WKT and geo:wktLiteral (both of the use CRS84); further, Geotools do not reverse longitude/latitude, so we use the official EPSG:4326 ordering, that is, Lat/Long
2014-09-17 Babis Nikolaou now GeoJSON features encode their geometries in CRS84 (the default). This change was done because otherwise we should be referring to OGC CRS URNs and not to the EPSG:<code> style that was previously the case
2014-09-16 Babis Nikolaou some comments and formatting
2014-09-16 Babis Nikolaou introduced constant for the default SRID of MonetDB and PostGIS
2014-09-16 Babis Nikolaou MonetDB.createWellKnownTextLiteralGeoValueForSelectConstructs should create WKTLiterals instead of WKT ones
2014-09-16 Babis Nikolaou added some comments
2014-09-16 Babis Nikolaou removed some comments
2014-09-20 Babis Nikolaou fixed a bug in which postgis:ST_Centroid did not work in the SELECT clause with input geometries from the database
2014-09-20 Babis Nikolaou corrected copyright notices

2014-09-19 Babis Nikolaou fixed bug #53
2014-09-19 Babis Nikolaou added tests for geof:getSRID(); see bug #32 (I have fixed it, but not commited it yet)
