charnik@1425 1 * Fixed a bug that would not return the correct spatial datatype of a
charnik@1425 2 projected geometry literal stored in the database.
charnik@1425 3 (bug #71:
charnik@1425 4
charnik@1425 5 * Now, geometries expressed in CRS84 and a `geo:wktLiteral' datatype
charnik@1425 6 are assigned the correct CRS, i.e., EPSG:4326 with a longitude
charnik@1425 7 latitude axis order.
charnik@1425 8
charnik@1425 9 * Now, we report a parse error when a constant geometry given in a
charnik@1425 10 SELECT or HAVING clause is not well-formed according to the WKT
charnik@1425 11 specification.
charnik@1425 12 (bug #69:
charnik@1425 13
charnik@1425 14 * Function `geof:convexHull' is now supported in a Having clause.
charnik@1425 15
charnik@1425 16 * Fixed older implementation of `strdf:distance' that would expect two
charnik@1425 17 arguments instead of three when present in a HAVING clause.
charnik@1425 18
charnik@1425 19 * Fixed a bug that would cause a class cast exception for grounded
charnik@1425 20 expressions with function nesting in the SELECT or HAVING clause.
charnik@1425 21
charnik@1425 22 * Fixed a bug in which `postgis:ST_Centroid' did not work in the SELECT
charnik@1425 23 clause with input geometries from the database.
charnik@1425 24
charnik@1425 25 * Fixed a bug that `geof:getSRID' would return an integer instead of a
charnik@1425 26 the URI corrresponding to the CRS that the input geometry was
charnik@1425 27 expressed.
charnik@1425 28 (bug #32:
charnik@1425 29
charnik@1368 30 * Fixed a bug that would raise an exception for queries involving two
charnik@1368 31 UNION graph patterns and a projection to a predicate or a URI in
charnik@1368 32 general.
charnik@1368 33 (bug #53:

charnik@1334 36
charnik@1334 37 * Version 3.2.10 released.
charnik@1334 38
charnik@1360 39 * The test suite of Strabon has now reached a mature level. It
charnik@1360 40 contains tests for both stSPARQL and GeoSPARQL query languages and
charnik@1360 41 most of the compliance tests covered in the specification of
charnik@1360 42 GeoSPARQL (well, only those tests for the components that we have
charnik@1360 43 chosen to implement).
charnik@1360 44
charnik@1360 45 * The endpoint now parses Accept headers with multiple values and uses
charnik@1360 46 the first mimetype corresponding to a valid stSPARQLQueryResultFormat.
charnik@1360 47 (bug #64:
charnik@1360 48
charnik@1360 49 * The endpoint now registers a handler for SIGTERM signals, so that if
charnik@1360 50 it is run from the command-line (endpoint-exec), then the closing of
charnik@1360 51 the connection will be ultimately called.
charnik@1360 52 (bug #40:
charnik@1360 53
johnvl@1355 54 * Strabon goes debian v1. the endpoint-exec jar is now given in a .deb
johnvl@1355 55 format. By dpkg-ing it, one can run a stand alone strabon endpoint
johnvl@1355 56 locally.
johnvl@1355 57 (bug #45
johnvl@1355 58
johnvl@1351 59 * Fixed a bug in which Strabon hanged when a unary spatial construct
johnvl@1351 60 had a ternary spatial construct as argument.
charnik@1360 61 (bug #45
johnvl@1351 62
charnik@1360 63 * Fixed a bug according to which spatial functions in ORDER BY were not
charnik@1360 64 evaluated at all.
charnik@1360 65 (bug #62:
charnik@1360 66
charnik@1360 67 * Fixed a bug according to which spatial boolean functions appearing
charnik@1360 68 in the SELECT clause were raising a NULL pointer exception.
charnik@1360 69 (bug #34:
mkarpat@1349 70
sgian@1340 71 * Fixed a bug in queries that contain variables that exist inside
sgian@1340 72 spatial functions in select and do not exist in the where clause
sgian@1340 73 made Strabon throw a NULL pointer exception.
sgian@1340 74 (bug #51
sgian@1340 75
charnik@1334 76 * Various changes in the interface and behavior of Strabon Endpoint:
charnik@1334 77 - Revised the logos and the sample queries.
charnik@1334 78 - Results query limit is set to zero (unlimited).
charnik@1334 79 - Users can now store RDF data that is present in a file on the
charnik@1334 80 client side (the file is uploaded to the server).
charnik@1334 81 - Credentials are now required for uploading files or executing
charnik@1334 82 UPDATE queries, unless Strabon Endpoint runs locally (localhost).
charnik@1334 83 - When viewing the results of queries in HTML, any URI is now an
charnik@1334 84 active link to itself. Previously, that URI was being DESCRIBEd
charnik@1334 85 and one was being transferred to a page viewing the result of the
charnik@1334 86 DESCRIBE query.
charnik@1334 87 - The DESCRIBE functionality can now be accessed through the menu bar.
charnik@1334 88
sgian@1329 89 * Fixed a bug where strdf:intersection function did not work as an
charnik@1360 90 aggregate when used without 'GROUP BY'.
charnik@1360 91 (bug #46
sgian@1329 92
mkarpat@1349 93

charnik@932 95
charnik@932 96 * Version 3.2.9 released.
charnik@932 97
Konstantina@1235 98 * Added support for the following google chart types: PieChart,
Konstantina@1235 99 AreaChart and ColumnChart to strabon endpoint.
Konstantina@1235 100
Konstantina@1265 101 * Added Timemap as new results format in Strabon endpoint. This
Konstantina@1265 102 option displays results in a map and a timeline on the same time,
Konstantina@1265 103 using the Timemap js library (
Konstantina@1265 104 The KMLWriter has been extended for that purpose, by transforming
Konstantina@1265 105 dateTime values that are included in the result set into the respective
Konstantina@1265 106 TimeStamp KML primitive (
Konstantina@1265 107 In the "temporals" branch, the values of the strdf:period datatype
Konstantina@1265 108 are converted into the respective KML TimeSpan primitive.
Konstantina@1265 109
charnik@1117 110 * Added extension function <> which is
charnik@1117 111 mapped to the ST_Centroid(geometry) extension function of PostGIS.
charnik@1117 112 See also: <>.
charnik@1117 113
charnik@1115 114 * Added extension function <> which is
charnik@1115 115 mapped to the ST_MakeLine(geometry, geometry) extension function of
charnik@1115 116 PostGIS. See also: <>.
charnik@1115 117
charnik@1115 118 * Added PostGIS vocabulary class.
charnik@1115 119
charnik@1012 120 * Added support of all SPARQL result types provided by Sesame (json,
charnik@1012 121 xml, csv, tsv, binary). To get the respective writer, just prepend the
charnik@1012 122 string "SPARQL/", e.g., "SPARQL/JSON". This is to ensure that we
charnik@1012 123 support all SPARQL result formats of the SPARQL Protocol.
charnik@1012 124
charnik@990 125 * Fixed a bug where a non-implemented extension function would make
charnik@990 126 Strabon throw a NULL pointer exception. Now we get away with it
charnik@990 127 through a warning.
charnik@990 128
charnik@990 129 * Strabon endpoint now publishes the URIs of the supported units of
charnik@990 130 measure for use in strdf:distance and geof:distance functions of
charnik@990 131 stSPARQL and GeoSPARQL, respectively. The URIs are those defined by
charnik@990 132 OGC Units of Measure 1.0 specification which may be found at
charnik@990 133 Strabon endpoint publishes
charnik@990 134 the URIs at http://localhost:8080/endpoint/Capabilities.
charnik@990 135
charnik@1004 136 * Created new module with name 'vocab` and artifactId
charnik@1004 137 'strabon-vocabulary` and moved there. Other
charnik@1004 138 vocabularies have been added as well, such as Simple Features, and
charnik@1004 139 GeoSPARQL.
charnik@966 140
charnik@964 141 * Strabon endpoint now publishes the URIs of the supported extension
charnik@964 142 functions for stSPARQL and GeoSPARQL. One should access them by
charnik@964 143 hitting the link http://localhost:8080/endpoint/Capabilities.
charnik@964 144
charnik@932 145 * Support for parsing EPSG URIs in geometry literals with datatype
charnik@932 146 geo:wktLiteral.
charnik@932 147 (bug #33:
charnik@932 148
kallirroi@1273 149 * Endpoint Client now supports querying of Virtuoso and Parliament endpoints.
kallirroi@1273 150
kallirroi@1273 151 * Endpoint Client now supports store and update operations, but only
kallirroi@1273 152 for Strabon Endpoints.
kallirroi@1273 153
kallirroi@1143 154 * GeoSPARQL functions sfCrosses, sfOverlaps, ehOverlaps do not use the
kallirroi@1143 155 ST_Relate PostGIS function (bug #24:
kallirroi@1143 156
kallirroi@1143 157 * All Simple Features functions of GeoSPARQL do not use the ST_Relate
kallirroi@1143 158 PostGIS function
psmeros@1176 159
Konstantina@1174 160 * Added diffTime function. This function performs the difference
Konstantina@1174 161 between two literals of xsd:time datatype and returns a literal of
Konstantina@1174 162 the xsd:time datatype as well.
psmeros@1175 163
psmeros@1175 164 * Added a testsuite package in default branch. Full tester guide can be found
psmeros@1175 165 in README. Among other, most of GeoSPARQL compliance tests
psmeros@1175 166 (, pg. 53) have been
psmeros@1175 167 implemented.
kallirroi@1143 168
sgian@1267 169 * Changed the definition and implementation of strdf:distance function, by
sgian@1267 170 adopting the definition of GeoSPARQL.
sgian@1267 171 (bug #23:
sgian@1267 172
sgian@1268 173 * Changed the definition and implementation of strdf:buffer function, by
sgian@1268 174 adopting the definition of GeoSPARQL.
sgian@1268 175 (bug #35:
sgian@1268 176
sgian@1269 177 * Added geof:distance and geof:buffer functions, which have the same definition
sgian@1269 178 with strdf:distance and strdf:buffer respectively.
sgian@1276 179 (bug #32:
sgian@1269 180
sgian@1270 181 * Added a download button when performing describe and construct queries at the
sgian@1270 182 endpoint.
sgian@1270 183 (bug #38:
sgian@1270 184
sgian@1270 185 * Fixed a bug, where XMLWriter and TSVWriter did not return geometries with the
sgian@1270 186 SRID.
sgian@1270 187 (bug #47:
sgian@1270 188
sgian@1266 189 * Fixed a bug where the GeoSPARQL construct functions did not return the datatype
sgian@1266 190 geo:wktLiteral datatype but strdf:WKT.

charnik@645 193
charnik@853 194 * Version 3.2.8 released.
charnik@853 195
charnik@926 196 * Added support for handling (storing/querying) GeoSPARQL datatypes.
charnik@926 197 (bug #31:
charnik@926 198
charnik@926 199 * Fixed a bug in StoreOp that wouldn't close the connection, neither
charnik@926 200 rollback the transaction upon an exception. This had as a side effect
charnik@926 201 the abnormal termination of StoreOp (through for example the use of
charnik@926 202 Ctrl-C signal) which was leaving the database locked.
charnik@926 203
charnik@926 204 * Fixed bug where spatial aggregates (e.g., union) didn't work as
charnik@926 205 expected when the query didn't contain a `GROUP BY' clause.
charnik@926 206 (bug #22:
charnik@926 207
charnik@926 208 * Updated GeoSPARQL namespaces and fixed function names to comply with
charnik@926 209 the GeoSPARQL specification.

charnik@853 213
kkyzir@801 214 * Version 3.2.7 released.
kkyzir@801 215
ggarbis@854 216 * Add an extension function
ggarbis@854 217 <> for computing the
ggarbis@854 218 span (in milliseconds) between two timestamps.
ggarbis@854 219
ggarbis@854 220 * Added an <endpoint-exec> module. This module builds an executable jar file
ggarbis@854 221 with an embedded Apache Tomcat 7. To create and run the executable jar just
ggarbis@854 222 type:
ggarbis@854 223 $ mvn clean package
ggarbis@854 224 $ java -jar endpoint-exec/target/strabon-endpoint-executable-*.jar
charnik@853 225
charnik@810 226 * Modified strabon script and postgis/monetdb.StoreOP class to get an
charnik@810 227 option for storing a RDF file in a named graph. Moreover, the RDF
charnik@810 228 format of the input RDF file now is given as an option (still, if it
charnik@810 229 is missing, it is assumed that the input is in N-TRIPLES format). The
charnik@810 230 option for the format is -f and the option for the named graph is -g
charnik@810 231 (takes a URI as an argument).
charnik@810 232
kkyzir@801 233 * Modified the names of the stSPARQL extension functions that
kkyzir@801 234 utilize the minimum bounding boxes of the involved geometries.
kkyzir@801 235
charnik@811 236 Tue Dec 11 19:33:45 2012 Pyravlos Team
charnik@811 237
kkyzir@800 238 * Version 3.2.6 released.
kkyzir@800 239
kkyzir@800 240 * Modified the names of the stSPARQL extension functions to comply
kkyzir@801 241 with the OGC Simple Features Access standard.
kkyzir@800 242
charnik@811 243 Tue Dec 11 00:11:43 2012 Pyravlos Team
charnik@811 244
charnik@645 245 * Version 3.2.5 released.
charnik@645 246
charnik@811 247 * Added support for querying temporal information. This functionality
Konstantina@848 248 may be found in the `temporals' branch.
Konstantina@848 249
charnik@849 250 The datatypes <> and
charnik@849 251 <> are used to
charnik@849 252 represent periods and instants respectively.
Konstantina@848 253
charnik@849 254 The valid time time of triples is represented using quadtruples,
charnik@849 255 with the valid time annotation(instant or period) being the
charnik@849 256 fourth element of the quad. In the same way, temporal triple
charnik@849 257 patterns are used in queries to retrieve the valid time of
charnik@849 258 triples.
Konstantina@848 259
charnik@849 260 Some functions have been renamed (their URIs have changed) to
charnik@849 261 follow the names of the respective relations of Allen's
charnik@849 262 interval algebra and other functions have been added.
Konstantina@848 263
Konstantina@848 264 The following temporal functions are supported:
charnik@849 265 during, periodOverlaps, equalsPeriod, nequalsPeriod, adjacent,
charnik@849 266 before, after, overleft, overright, meets, starts, finishes,
charnik@849 267 period_intersect, period_union, preceding_period, and
charnik@849 268 succeeding_period.
Konstantina@848 269
charnik@759 270 * Changed behaviour of Strabon and Strabon Endpoint for connecting to
charnik@759 271 a spatially-enabled database. Only one instance of Strabon is allowed
charnik@759 272 at a time.
charnik@759 273
charnik@688 274 * Implemented a Java client for Strabon Endpoint. The client should be
charnik@688 275 used only with endpoint versions >=3.2.5. The implementation may be
charnik@688 276 found int the `endpoint-client' submodule of maven. Currently, only
charnik@688 277 querying of Strabon Endpoints is supported.
charnik@688 278
charnik@662 279 * Added support for requesting the capabilities of Strabon Endpoint
charnik@662 280 (fixes Bug #20 <>). See
charnik@662 281 changesets f840796400bf and ?<TBC>? for specific details and how you
charnik@662 282 can determine the capabilities of older endpoints (versions <= 3.2.4).
charnik@662 283
charnik@658 284 * Updated KML writer to include the projected variables of an stSPARQL
charnik@658 285 query in "ExtendedData" and "Data" tags. This is the proper way to
charnik@658 286 do it if we need to convert a KML to a ESRI shapefile and also include
charnik@658 287 such information as attributes for a feature. See related pages from
charnik@658 288 KML specification:
charnik@658 289 <>
charnik@658 290 <>
charnik@658 291
charnik@645 292 * Added user authentication for storing RDF data through Strabon
charnik@662 293 Endpoint. The credentials are specified in
charnik@662 294 WEB-INF/ file.
charnik@645 295
charnik@645 296 * Strabon Endpoints now limits the number of the results to a maximum
charnik@645 297 one. The maximum number is specified in the beans.xml file. This
charnik@645 298 corresponds to parameter "maxLimit". The endpoint script has also been
charnik@645 299 updated correspondingly; the limit can be given using the option "-l".
charnik@645 300 One can disable limiting of query results, by setting the "maxLimit"
charnik@645 301 parameter to 0. Addresses Bug #6
charnik@645 302 (<>).
charnik@645 303
charnik@645 304 * Added "Known Issues" section to README.
charnik@645 305
charnik@645 306 * Added -m (more memory) and -M (much more memory) options in strabon
charnik@645 307 script for out-of-memory exceptions.
charnik@645 308
charnik@849 309 * Fixed Bug #10 (<>). Now
charnik@849 310 KMLWriter handles more geometric types (other than polygons). See
charnik@849 311 changeset 9a3bfee64a39.
charnik@645 312
charnik@645 313 * Menu and navigation in Strabon Endpoint has changed to use jquery.
charnik@645 314 The menu is now populated using the queries placed inside the beans.xml.
charnik@645 315
charnik@645 316 * Added BrowseBean and browse.jsp for browsing the RDF data using the
charnik@645 317 Strabon Endpoint.
