charnik@1506 1 Wed Mar 11 21:02:48 2015 Pyravlos Team
johnvl@1508 2
johnvl@1520 3 * Bug #73, modified appendBuffer function to take the srid into
johnvl@1520 4 consideration even if the argument is a constant (wktLiteral
johnvl@1520 5 or strdf literal)
johnvl@1520 6
johnvl@1508 7 * Update jar references on scripts used by the debian packaging.
johnvl@1508 8 Previously these references pointed only (incorrectly) to
johnvl@1508 9 SNAPSHOTs.
charnik@1506 10
johnvl@1507 11 * Updated package names (since repositories cannot include capital
johnvl@1507 12 letters + runtime and endpoint-exec must have different names
johnvl@1507 13
charnik@1506 14 * Version 3.3.1 released.
charnik@1506 15
johnvl@1484 16 * Bug #58, added script that is invoked my maven to also update the
johnvl@1484 17 version described in the deb/control file of the runtime and
johnvl@1484 18 endpoint-exec components.
johnvl@1484 19
johnvl@1464 20 * Related to bug #58, but it generally enhances Strabon; The runtime
johnvl@1464 21 component has also been debianized. Dependencies are added to
johnvl@1464 22 /usr/share/jdeb/lib/strabon-runtime. ClassPath and strabon script
johnvl@1464 23 have also been updated accordingly (strabon-cmd)
johnvl@1464 24
johnvl@1457 25 * Bug #58: Maven creates the debian package conditionally. Use
johnvl@1457 26 -Ddebian=true in the mvn package command.
johnvl@1457 27
johnvl@1456 28 * Bug #58: Added dependencies - java, postgresql, tomcat. Also, added
johnvl@1456 29 a strabon-init script that detects the postgis installation path
johnvl@1456 30 and sets up the template_postgis. Finally the script creates a db
johnvl@1456 31 called "endpoint" (assuming it does not already exist) that is used
johnvl@1456 32 for the strabon-endpoint command.
gstam@1485 33
gstam@1485 34 * Fixed an issue that returned null SRID when unmarshalling GML geometries if
gstam@1485 35 the SRID did not follow one of the supported formats by GML-JTS. To fix that
gstam@1485 36 we added a function that handles these cases by reading the userData variable
gstam@1485 37 that JTS provides.
johnvl@1456 38
sgian@1450 39 * Fixed a bug that would return no results when a variable that results
sgian@1450 40 from a BIND clause appears in the FILTER or in the projection of a
sgian@1450 41 query and is inside a spatial function.
sgian@1450 42 (bug #78: http://bug.strabon.di.uoa.gr/ticket/78)
sgian@1450 43
charnik@1444 44 * Fixed the precision of the geometry literals in GeoJSON writer. Now,
charnik@1444 45 this defaults to the precision model of JTS (equals to 16). Prior to
charnik@1444 46 this it was fixed to 4.
charnik@1444 47
charnik@1444 48 * Now the GeoJSON writer is aware of the kind of typed literals (e.g.,
charnik@1444 49 numeric, boolean, calendar, etc.) and prints the corresponding
charnik@1444 50 values according to these types.
charnik@1444 51
sgian@1437 52 * Fixed a bug that would not return the correct result or would fail
sgian@1437 53 when a spatial function involved a constant and a variable.
sgian@1437 54 (bug #74: http://bug.strabon.di.uoa.gr/ticket/74)
sgian@1437 55
charnik@1425 56 * Fixed a bug that would not return the correct spatial datatype of a
charnik@1425 57 projected geometry literal stored in the database.
charnik@1425 58 (bug #71: http://bug.strabon.di.uoa.gr/ticket/71)
charnik@1425 59
charnik@1425 60 * Now, geometries expressed in CRS84 and a `geo:wktLiteral' datatype
charnik@1425 61 are assigned the correct CRS, i.e., EPSG:4326 with a longitude
charnik@1425 62 latitude axis order.
charnik@1425 63
charnik@1425 64 * Now, we report a parse error when a constant geometry given in a
charnik@1425 65 SELECT or HAVING clause is not well-formed according to the WKT
charnik@1425 66 specification.
charnik@1425 67 (bug #69: http://bug.strabon.di.uoa.gr/ticket/69)
charnik@1425 68
charnik@1425 69 * Function `geof:convexHull' is now supported in a Having clause.
charnik@1425 70
charnik@1425 71 * Fixed older implementation of `strdf:distance' that would expect two
charnik@1425 72 arguments instead of three when present in a HAVING clause.
charnik@1425 73
charnik@1425 74 * Fixed a bug that would cause a class cast exception for grounded
charnik@1425 75 expressions with function nesting in the SELECT or HAVING clause.
charnik@1425 76
charnik@1425 77 * Fixed a bug in which `postgis:ST_Centroid' did not work in the SELECT
charnik@1425 78 clause with input geometries from the database.
charnik@1425 79
charnik@1425 80 * Fixed a bug that `geof:getSRID' would return an integer instead of a
charnik@1425 81 the URI corrresponding to the CRS that the input geometry was
charnik@1425 82 expressed.
charnik@1425 83 (bug #32: http://bug.strabon.di.uoa.gr/ticket/32)
charnik@1368 84 * Fixed a bug that would raise an exception for queries involving two
charnik@1368 85 UNION graph patterns and a projection to a predicate or a URI in
charnik@1368 86 general.
charnik@1368 87 (bug #53: http://bug.strabon.di.uoa.gr/ticket/53)

charnik@1364 89 Wed Sep 17 20:14:12 2014 Pyravlos Team
charnik@1334 90
charnik@1334 91 * Version 3.2.10 released.
charnik@1334 92
charnik@1360 93 * The test suite of Strabon has now reached a mature level. It
charnik@1360 94 contains tests for both stSPARQL and GeoSPARQL query languages and
charnik@1360 95 most of the compliance tests covered in the specification of
charnik@1360 96 GeoSPARQL (well, only those tests for the components that we have
charnik@1360 97 chosen to implement).
charnik@1360 98
charnik@1360 99 * The endpoint now parses Accept headers with multiple values and uses
charnik@1360 100 the first mimetype corresponding to a valid stSPARQLQueryResultFormat.
charnik@1360 101 (bug #64: http://bug.strabon.di.uoa.gr/ticket/64)
charnik@1360 102
charnik@1360 103 * The endpoint now registers a handler for SIGTERM signals, so that if
charnik@1360 104 it is run from the command-line (endpoint-exec), then the closing of
charnik@1360 105 the connection will be ultimately called.
charnik@1360 106 (bug #40: http://bug.strabon.di.uoa.gr/ticket/40)
charnik@1360 107
johnvl@1355 108 * Strabon goes debian v1. the endpoint-exec jar is now given in a .deb
johnvl@1355 109 format. By dpkg-ing it, one can run a stand alone strabon endpoint
johnvl@1355 110 locally.
johnvl@1355 111 (bug #45 http://bug.strabon.di.uoa.gr/ticket/58)
johnvl@1355 112
johnvl@1351 113 * Fixed a bug in which Strabon hanged when a unary spatial construct
johnvl@1351 114 had a ternary spatial construct as argument.
charnik@1360 115 (bug #45 http://bug.strabon.di.uoa.gr/ticket/45)
johnvl@1351 116
charnik@1360 117 * Fixed a bug according to which spatial functions in ORDER BY were not
charnik@1360 118 evaluated at all.
charnik@1360 119 (bug #62: http://bug.strabon.di.uoa.gr/ticket/62)
charnik@1360 120
charnik@1360 121 * Fixed a bug according to which spatial boolean functions appearing
charnik@1360 122 in the SELECT clause were raising a NULL pointer exception.
charnik@1360 123 (bug #34: http://bug.strabon.di.uoa.gr/ticket/34)
mkarpat@1349 124
sgian@1340 125 * Fixed a bug in queries that contain variables that exist inside
sgian@1340 126 spatial functions in select and do not exist in the where clause
sgian@1340 127 made Strabon throw a NULL pointer exception.
sgian@1340 128 (bug #51 https://bug.strabon.di.uoa.gr/ticket/51)
sgian@1340 129
charnik@1334 130 * Various changes in the interface and behavior of Strabon Endpoint:
charnik@1334 131 - Revised the logos and the sample queries.
charnik@1334 132 - Results query limit is set to zero (unlimited).
charnik@1334 133 - Users can now store RDF data that is present in a file on the
charnik@1334 134 client side (the file is uploaded to the server).
charnik@1334 135 - Credentials are now required for uploading files or executing
charnik@1334 136 UPDATE queries, unless Strabon Endpoint runs locally (localhost).
charnik@1334 137 - When viewing the results of queries in HTML, any URI is now an
charnik@1334 138 active link to itself. Previously, that URI was being DESCRIBEd
charnik@1334 139 and one was being transferred to a page viewing the result of the
charnik@1334 140 DESCRIBE query.
charnik@1334 141 - The DESCRIBE functionality can now be accessed through the menu bar.
charnik@1334 142
sgian@1329 143 * Fixed a bug where strdf:intersection function did not work as an
charnik@1360 144 aggregate when used without 'GROUP BY'.
charnik@1360 145 (bug #46 https://bug.strabon.di.uoa.gr/ticket/46)

charnik@1280 148 Sat Oct 19 23:37:23 2013 Pyravlos Team
charnik@932 149
charnik@932 150 * Version 3.2.9 released.
charnik@932 151
Konstantina@1235 152 * Added support for the following google chart types: PieChart,
Konstantina@1235 153 AreaChart and ColumnChart to strabon endpoint.
Konstantina@1235 154
Konstantina@1265 155 * Added Timemap as new results format in Strabon endpoint. This
Konstantina@1265 156 option displays results in a map and a timeline on the same time,
Konstantina@1265 157 using the Timemap js library (http://code.google.com/p/timemap/).
Konstantina@1265 158 The KMLWriter has been extended for that purpose, by transforming
Konstantina@1265 159 dateTime values that are included in the result set into the respective
Konstantina@1265 160 TimeStamp KML primitive (https://developers.google.com/kml/documentation/time).
Konstantina@1265 161 In the "temporals" branch, the values of the strdf:period datatype
Konstantina@1265 162 are converted into the respective KML TimeSpan primitive.
Konstantina@1265 163
charnik@1117 164 * Added extension function <http://postgis.net/ST_Centroid> which is
charnik@1117 165 mapped to the ST_Centroid(geometry) extension function of PostGIS.
charnik@1117 166 See also: <http://postgis.org/docs/ST_Centroid.html>.
charnik@1117 167
charnik@1115 168 * Added extension function <http://postgis.net/ST_MakeLine> which is
charnik@1115 169 mapped to the ST_MakeLine(geometry, geometry) extension function of
charnik@1115 170 PostGIS. See also: <http://postgis.org/docs/ST_MakeLine.html>.
charnik@1115 171
charnik@1115 172 * Added PostGIS vocabulary class.
charnik@1115 173
charnik@1012 174 * Added support of all SPARQL result types provided by Sesame (json,
charnik@1012 175 xml, csv, tsv, binary). To get the respective writer, just prepend the
charnik@1012 176 string "SPARQL/", e.g., "SPARQL/JSON". This is to ensure that we
charnik@1012 177 support all SPARQL result formats of the SPARQL Protocol.
charnik@1012 178
charnik@990 179 * Fixed a bug where a non-implemented extension function would make
charnik@990 180 Strabon throw a NULL pointer exception. Now we get away with it
charnik@990 181 through a warning.
charnik@990 182
charnik@990 183 * Strabon endpoint now publishes the URIs of the supported units of
charnik@990 184 measure for use in strdf:distance and geof:distance functions of
charnik@990 185 stSPARQL and GeoSPARQL, respectively. The URIs are those defined by
charnik@990 186 OGC Units of Measure 1.0 specification which may be found at
charnik@990 187 http://www.opengis.net/def/uom/OGC/1.0/. Strabon endpoint publishes
charnik@990 188 the URIs at http://localhost:8080/endpoint/Capabilities.
charnik@990 189
charnik@1004 190 * Created new module with name 'vocab` and artifactId
charnik@1004 191 'strabon-vocabulary` and moved GeoConstants.java there. Other
charnik@1004 192 vocabularies have been added as well, such as Simple Features, and
charnik@1004 193 GeoSPARQL.
charnik@966 194
charnik@964 195 * Strabon endpoint now publishes the URIs of the supported extension
charnik@964 196 functions for stSPARQL and GeoSPARQL. One should access them by
charnik@964 197 hitting the link http://localhost:8080/endpoint/Capabilities.
charnik@964 198
charnik@932 199 * Support for parsing EPSG URIs in geometry literals with datatype
charnik@932 200 geo:wktLiteral.
charnik@932 201 (bug #33: http://bug.strabon.di.uoa.gr/ticket/33)
Konstantina@1142 202
kallirroi@1273 203 * Endpoint Client now supports querying of Virtuoso and Parliament endpoints.
kallirroi@1273 204
kallirroi@1273 205 * Endpoint Client now supports store and update operations, but only
kallirroi@1273 206 for Strabon Endpoints.
kallirroi@1273 207
Konstantina@1142 208 *Modified the NQUADSTranslator so that the rewritten triples are
Konstantina@1142 209 immediately flushed to the database once they are created.
Konstantina@1142 210
Konstantina@1142 211 *In the N-Quads format, the fourth element is *optional*. Made proper
Konstantina@1142 212 modification to the storage manager to coply to the specification
Konstantina@1142 213 described here: http://sw.deri.org/2008/07/n-quads/. Now files in
Konstantina@1142 214 NQUADS format can contain quads *or* triples in order to be stored
Konstantina@1142 215 successfully in Strabon.
Konstantina@1142 216
Konstantina@1142 217 *Fixed bug that occurs when storing periods having "UC" as ending
Konstantina@1142 218 point.
Konstantina@1142 219
Konstantina@1142 220 *Added an initial set of tests on temporal operations in the
Konstantina@1142 221 testsuite module.
Konstantina@1158 222
Konstantina@1158 223 *Completed support for temporal updates
Konstantina@1158 224
Konstantina@1158 225 *Moved vocabulary related to the temporal features of Strabon to the
Konstantina@1158 226 respective "vocabulary" project
charnik@932 227
Konstantina@1168 228 *The evaluation of temporal joins in the database does not produce
Konstantina@1168 229 cartesian products in the database
charnik@932 230
kallirroi@1143 231 * GeoSPARQL functions sfCrosses, sfOverlaps, ehOverlaps do not use the
kallirroi@1143 232 ST_Relate PostGIS function (bug #24: http://bug.strabon.di.uoa.gr/ticket/24)
kallirroi@1143 233
kallirroi@1143 234 * All Simple Features functions of GeoSPARQL do not use the ST_Relate
kallirroi@1143 235 PostGIS function
psmeros@1176 236
Konstantina@1174 237 * Added diffTime function. This function performs the difference
Konstantina@1174 238 between two literals of xsd:time datatype and returns a literal of
Konstantina@1174 239 the xsd:time datatype as well.
psmeros@1175 240
psmeros@1175 241 * Added a testsuite package in default branch. Full tester guide can be found
psmeros@1175 242 in README. Among other, most of GeoSPARQL compliance tests
psmeros@1175 243 (https://portal.opengeospatial.org/files/?artifact_id=47664, pg. 53) have been
psmeros@1175 244 implemented.
kallirroi@1143 245
sgian@1267 246 * Changed the definition and implementation of strdf:distance function, by
sgian@1267 247 adopting the definition of GeoSPARQL.
sgian@1267 248 (bug #23: http://bug.strabon.di.uoa.gr/ticket/23)
sgian@1267 249
sgian@1268 250 * Changed the definition and implementation of strdf:buffer function, by
sgian@1268 251 adopting the definition of GeoSPARQL.
sgian@1268 252 (bug #35: http://bug.strabon.di.uoa.gr/ticket/35)
sgian@1268 253
sgian@1269 254 * Added geof:distance and geof:buffer functions, which have the same definition
sgian@1269 255 with strdf:distance and strdf:buffer respectively.
sgian@1276 256 (bug #32: http://bug.strabon.di.uoa.gr/ticket/32)
sgian@1269 257
sgian@1270 258 * Added a download button when performing describe and construct queries at the
sgian@1270 259 endpoint.
sgian@1270 260 (bug #38: http://bug.strabon.di.uoa.gr/ticket/38)
sgian@1270 261
sgian@1270 262 * Fixed a bug, where XMLWriter and TSVWriter did not return geometries with the
sgian@1270 263 SRID.
sgian@1270 264 (bug #47: http://bug.strabon.di.uoa.gr/ticket/47)
sgian@1270 265
sgian@1266 266 * Fixed a bug where the GeoSPARQL construct functions did not return the datatype
sgian@1266 267 geo:wktLiteral datatype but strdf:WKT.
sgian@1266 268
charnik@927 269 Tue Mar 26 13:28:26 2013 Pyravlos Team
charnik@645 270
charnik@853 271 * Version 3.2.8 released.
charnik@853 272
charnik@926 273 * Added support for handling (storing/querying) GeoSPARQL datatypes.
charnik@926 274 (bug #31: http://bug.strabon.di.uoa.gr/ticket/31)
charnik@926 275
charnik@926 276 * Fixed a bug in StoreOp that wouldn't close the connection, neither
charnik@926 277 rollback the transaction upon an exception. This had as a side effect
charnik@926 278 the abnormal termination of StoreOp (through for example the use of
charnik@926 279 Ctrl-C signal) which was leaving the database locked.
charnik@926 280
charnik@926 281 * Fixed bug where spatial aggregates (e.g., union) didn't work as
charnik@926 282 expected when the query didn't contain a `GROUP BY' clause.
charnik@926 283 (bug #22: http://bug.strabon.di.uoa.gr/ticket/22)
charnik@926 284
charnik@926 285 * Updated GeoSPARQL namespaces and fixed function names to comply with
charnik@926 286 the GeoSPARQL specification.
charnik@926 287 (bug #25: http://bug.strabon.di.uoa.gr/ticket/25)
Konstantina@1142 288
Konstantina@1142 289 *Added preliminary tests on temporal functions in the respective
Konstantina@1142 290 "test" package of the runtime module.
Konstantina@1142 291
Konstantina@1142 292 *Added option to strabon and endpoint scripts to support storing
Konstantina@1142 293 files in NQUADS format.
Konstantina@1142 294
Konstantina@1142 295 *When a large file in NQUADS format is going to be stored, it is
Konstantina@1142 296 partitioned and stored in parts. This happens because the translation
Konstantina@1142 297 of quads to triples is a memory intensive job, so, translating and
Konstantina@1142 298 storing the file in batches increases performance.
Konstantina@1142 299

charnik@853 301 Wed Jan 09 18:06:41 2013 Pyravlos Team
charnik@853 302
kkyzir@801 303 * Version 3.2.7 released.
kkyzir@801 304
ggarbis@854 305 * Add an extension function
ggarbis@854 306 <http://strdf.di.uoa.gr/extensions/ontology#diffDateTime> for computing the
ggarbis@854 307 span (in milliseconds) between two timestamps.
ggarbis@854 308
ggarbis@854 309 * Added an <endpoint-exec> module. This module builds an executable jar file
ggarbis@854 310 with an embedded Apache Tomcat 7. To create and run the executable jar just
ggarbis@854 311 type:
ggarbis@854 312 $ mvn clean package
ggarbis@854 313 $ java -jar endpoint-exec/target/strabon-endpoint-executable-*.jar
charnik@853 314
charnik@810 315 * Modified strabon script and postgis/monetdb.StoreOP class to get an
charnik@810 316 option for storing a RDF file in a named graph. Moreover, the RDF
charnik@810 317 format of the input RDF file now is given as an option (still, if it
charnik@810 318 is missing, it is assumed that the input is in N-TRIPLES format). The
charnik@810 319 option for the format is -f and the option for the named graph is -g
charnik@810 320 (takes a URI as an argument).
charnik@810 321
kkyzir@801 322 * Modified the names of the stSPARQL extension functions that
kkyzir@801 323 utilize the minimum bounding boxes of the involved geometries.
Konstantina@1142 324
Konstantina@1142 325 *Fixed bug in the evaluation of temporal constructs.
Konstantina@1142 326
Konstantina@1142 327 *Fixed a major bug that occured when a temporal variable that also took part
Konstantina@1142 328 in a temporal join was projected.
Konstantina@1142 329
Konstantina@1142 330 *Renamed temporal extension functions to comply with the respective
Konstantina@1142 331 functions of Allen's temporal relations.
Konstantina@1142 332
Konstantina@1142 333 *Modified the implementation of the temporal relation functions
Konstantina@1142 334 "meets", "starts", "finishes", to comply with the semantics of the
Konstantina@1142 335 respective functions of Allen. These functions are not supported by
Konstantina@1142 336 PostgreSQL Temporal, so, in order to be evaluated in the database
Konstantina@1142 337 level, we implemented them as PostgreSQL extension functions.
Konstantina@1142 338 ATTENTION: In order to use these functions, the respective sql script
Konstantina@1142 339 that includes them should be loaded to the the temporally (and spa-
Konstantina@1142 340 tially) enabled database.

charnik@811 344
kkyzir@800 345 * Version 3.2.6 released.
kkyzir@800 346
kkyzir@800 347 * Modified the names of the stSPARQL extension functions to comply
kkyzir@801 348 with the OGC Simple Features Access standard.

charnik@645 352 * Version 3.2.5 released.
charnik@645 353
Konstantina@1142 354 * Added support for storing and querying temporal information.
Konstantina@1142 355 This functionality may be found in the `temporals' branch.
Konstantina@848 356
Konstantina@1142 357 *The datatypes <http://strdf.di.uoa.gr/ontology#period> and
charnik@849 358 <http://www.w3.org/2001/XMLSchema#dateTime> are used to
Konstantina@1142 359 represent periods and instants respectively.
Konstantina@848 360
Konstantina@1142 361 *The valid time time of triples is represented using quadtruples,
charnik@849 362 with the valid time annotation(instant or period) being the
Konstantina@1142 363 fourth element of the quad. Into this direction:
Konstantina@1142 364 *Strabon has been extended to support the NQUADS format. The
Konstantina@1142 365 respective Sesame packages (of version 2.6.9) that support
Konstantina@1142 366 this format are used.
Konstantina@1142 367
Konstantina@1142 368 *NQuadTranslator class has been created. This class uses the
Konstantina@1142 369 NQUADS parser which is available here: https://github.com/joshsh/sesametools/tree/develop/nquads.
Konstantina@1142 370 The initial version of this parser did not include support
Konstantina@1142 371 for literals as the fourth element of the quad. We exteded
Konstantina@1142 372 it to support the valid time representations described above.
Konstantina@1142 373
Konstantina@1142 374 *The NQUADSTranslator translates quads into triples using the
Konstantina@1142 375 named graph approach, similar to the one proposed by Tappolet
Konstantina@1142 376 et al. and described in http://dl.acm.org/citation.cfm?id=1561565.
Konstantina@1142 377
Konstantina@1142 378 *The rdbms level of Strabon has been extended to (i) support
Konstantina@1142 379 tha period datatype (ii) store the period values in the table
Konstantina@1142 380 period_values(id, period). The period column is of the period
Konstantina@1142 381 datatype, offered by the PostgreSQL Temporal extension (http://sourceforge.net/projects/pgsql-temporal/).
Konstantina@1142 382 Also, a GiST index is created on this column.
Konstantina@1142 383
Konstantina@1142 384 *A rewriting mechanism that converts quad graph patterns into
Konstantina@1142 385 triple partners using the named graphs approach has been
Konstantina@1142 386 implemented as a method of the runtime.generaldb.Strabon
Konstantina@1142 387 class.
Konstantina@1142 388
Konstantina@1142 389 *A big part of the temporal functions of stSPARQL has been
Konstantina@1142 390 imlemented. These functions include:
Konstantina@1142 391 *The temporal relation functions during, periodOverlaps,
Konstantina@1142 392 equalsPeriod, nequalsPeriod, adjacent, before, after,
Konstantina@1142 393 overleft, overright, meets, starts, finishes.
Konstantina@1142 394
Konstantina@1142 395 *The period constructors period_intersect, period_union,
Konstantina@1142 396 preceding_period, and succeeding_period. The last two
Konstantina@1142 397 constructors are implemented using the jtemporal library.
Konstantina@1142 398 The other functions are implemented in the database,
Konstantina@1142 399 being mapped into the respective functions of PostgreSQL
Konstantina@1142 400 Temporal. A complete reference of PostgreSQL Temporal
Konstantina@1142 401 can be found here: http://temporal.projects.pgfoundry.org/reference.html.
Konstantina@1142 402
Konstantina@1142 403 *The temporal constants "NOW" and "UC" (Until Changed)
Konstantina@1142 404 are supported.
Konstantina@1142 405
Konstantina@1142 406 *The vocabulary of the valid time dimension of stSPARQL can
Konstantina@1142 407 be found at the TemporalConstants class of the evaluation
Konstantina@1142 408 module.
Konstantina@1142 409
charnik@759 410 * Changed behaviour of Strabon and Strabon Endpoint for connecting to
charnik@759 411 a spatially-enabled database. Only one instance of Strabon is allowed
charnik@759 412 at a time.
charnik@759 413
charnik@688 414 * Implemented a Java client for Strabon Endpoint. The client should be
charnik@688 415 used only with endpoint versions >=3.2.5. The implementation may be
charnik@688 416 found int the `endpoint-client' submodule of maven. Currently, only
charnik@688 417 querying of Strabon Endpoints is supported.
charnik@688 418
charnik@662 419 * Added support for requesting the capabilities of Strabon Endpoint
charnik@662 420 (fixes Bug #20 <http://bug.strabon.di.uoa.gr/ticket/20>). See
charnik@662 421 changesets f840796400bf and ?<TBC>? for specific details and how you
charnik@662 422 can determine the capabilities of older endpoints (versions <= 3.2.4).
charnik@662 423
charnik@658 424 * Updated KML writer to include the projected variables of an stSPARQL
charnik@658 425 query in "ExtendedData" and "Data" tags. This is the proper way to
charnik@658 426 do it if we need to convert a KML to a ESRI shapefile and also include
charnik@658 427 such information as attributes for a feature. See related pages from
charnik@658 428 KML specification:
charnik@658 429 <https://developers.google.com/kml/documentation/kmlreference#extendeddata>
charnik@658 430 <https://developers.google.com/kml/documentation/extendeddata>
charnik@658 431
charnik@645 432 * Added user authentication for storing RDF data through Strabon
charnik@662 433 Endpoint. The credentials are specified in
charnik@662 434 WEB-INF/credentials.properties file.
charnik@645 435
charnik@645 436 * Strabon Endpoints now limits the number of the results to a maximum
charnik@645 437 one. The maximum number is specified in the beans.xml file. This
charnik@645 438 corresponds to parameter "maxLimit". The endpoint script has also been
charnik@645 439 updated correspondingly; the limit can be given using the option "-l".
charnik@645 440 One can disable limiting of query results, by setting the "maxLimit"
charnik@645 441 parameter to 0. Addresses Bug #6
charnik@645 442 (<http://bug.strabon.di.uoa.gr/ticket/6>).
charnik@645 443
charnik@645 444 * Added "Known Issues" section to README.
charnik@645 445
charnik@645 446 * Added -m (more memory) and -M (much more memory) options in strabon
charnik@645 447 script for out-of-memory exceptions.
charnik@645 448
charnik@849 449 * Fixed Bug #10 (<http://bug.strabon.di.uoa.gr/ticket/10>). Now
charnik@849 450 KMLWriter handles more geometric types (other than polygons). See
charnik@849 451 changeset 9a3bfee64a39.
charnik@645 452
charnik@645 453 * Menu and navigation in Strabon Endpoint has changed to use jquery.
charnik@645 454 The menu is now populated using the queries placed inside the beans.xml.
charnik@645 455
charnik@645 456 * Added BrowseBean and browse.jsp for browsing the RDF data using the
charnik@645 457 Strabon Endpoint.
