charnik@1368 1 * Fixed a bug that would raise an exception for queries involving two
charnik@1368 2 UNION graph patterns and a projection to a predicate or a URI in
charnik@1368 3 general.

charnik@1334 7
charnik@1334 8 * Version 3.2.10 released.
charnik@1334 9
charnik@1360 10 * The test suite of Strabon has now reached a mature level. It
charnik@1360 11 contains tests for both stSPARQL and GeoSPARQL query languages and
charnik@1360 12 most of the compliance tests covered in the specification of
charnik@1360 13 GeoSPARQL (well, only those tests for the components that we have
charnik@1360 14 chosen to implement).
charnik@1360 15
charnik@1360 16 * The endpoint now parses Accept headers with multiple values and uses
charnik@1360 17 the first mimetype corresponding to a valid stSPARQLQueryResultFormat.
charnik@1360 18 (bug #64:
charnik@1360 19
charnik@1360 20 * The endpoint now registers a handler for SIGTERM signals, so that if
charnik@1360 21 it is run from the command-line (endpoint-exec), then the closing of
charnik@1360 22 the connection will be ultimately called.
charnik@1360 23 (bug #40:
charnik@1360 24
johnvl@1355 25 * Strabon goes debian v1. the endpoint-exec jar is now given in a .deb
johnvl@1355 26 format. By dpkg-ing it, one can run a stand alone strabon endpoint
johnvl@1355 27 locally.
johnvl@1355 28 (bug #45
johnvl@1355 29
johnvl@1351 30 * Fixed a bug in which Strabon hanged when a unary spatial construct
johnvl@1351 31 had a ternary spatial construct as argument.
charnik@1360 32 (bug #45
johnvl@1351 33
charnik@1360 34 * Fixed a bug according to which spatial functions in ORDER BY were not
charnik@1360 35 evaluated at all.
charnik@1360 36 (bug #62:
charnik@1360 37
charnik@1360 38 * Fixed a bug according to which spatial boolean functions appearing
charnik@1360 39 in the SELECT clause were raising a NULL pointer exception.
charnik@1360 40 (bug #34:
mkarpat@1349 41
sgian@1340 42 * Fixed a bug in queries that contain variables that exist inside
sgian@1340 43 spatial functions in select and do not exist in the where clause
sgian@1340 44 made Strabon throw a NULL pointer exception.
sgian@1340 45 (bug #51
sgian@1340 46
charnik@1334 47 * Various changes in the interface and behavior of Strabon Endpoint:
charnik@1334 48 - Revised the logos and the sample queries.
charnik@1334 49 - Results query limit is set to zero (unlimited).
charnik@1334 50 - Users can now store RDF data that is present in a file on the
charnik@1334 51 client side (the file is uploaded to the server).
charnik@1334 52 - Credentials are now required for uploading files or executing
charnik@1334 53 UPDATE queries, unless Strabon Endpoint runs locally (localhost).
charnik@1334 54 - When viewing the results of queries in HTML, any URI is now an
charnik@1334 55 active link to itself. Previously, that URI was being DESCRIBEd
charnik@1334 56 and one was being transferred to a page viewing the result of the
charnik@1334 57 DESCRIBE query.
charnik@1334 58 - The DESCRIBE functionality can now be accessed through the menu bar.
charnik@1334 59
sgian@1329 60 * Fixed a bug where strdf:intersection function did not work as an
charnik@1360 61 aggregate when used without 'GROUP BY'.

charnik@932 66
charnik@932 67 * Version 3.2.9 released.
charnik@932 68
Konstantina@1235 69 * Added support for the following google chart types: PieChart,
Konstantina@1235 70 AreaChart and ColumnChart to strabon endpoint.
Konstantina@1235 71
Konstantina@1265 72 * Added Timemap as new results format in Strabon endpoint. This
Konstantina@1265 73 option displays results in a map and a timeline on the same time,
Konstantina@1265 74 using the Timemap js library (
Konstantina@1265 75 The KMLWriter has been extended for that purpose, by transforming
Konstantina@1265 76 dateTime values that are included in the result set into the respective
Konstantina@1265 77 TimeStamp KML primitive (
Konstantina@1265 78 In the "temporals" branch, the values of the strdf:period datatype
Konstantina@1265 79 are converted into the respective KML TimeSpan primitive.
Konstantina@1265 80
charnik@1117 81 * Added extension function <> which is
charnik@1117 82 mapped to the ST_Centroid(geometry) extension function of PostGIS.
charnik@1117 83 See also: <>.
charnik@1117 84
charnik@1115 85 * Added extension function <> which is
charnik@1115 86 mapped to the ST_MakeLine(geometry, geometry) extension function of
charnik@1115 87 PostGIS. See also: <>.
charnik@1115 88
charnik@1115 89 * Added PostGIS vocabulary class.
charnik@1115 90
charnik@1012 91 * Added support of all SPARQL result types provided by Sesame (json,
charnik@1012 92 xml, csv, tsv, binary). To get the respective writer, just prepend the
charnik@1012 93 string "SPARQL/", e.g., "SPARQL/JSON". This is to ensure that we
charnik@1012 94 support all SPARQL result formats of the SPARQL Protocol.
charnik@1012 95
charnik@990 96 * Fixed a bug where a non-implemented extension function would make
charnik@990 97 Strabon throw a NULL pointer exception. Now we get away with it
charnik@990 98 through a warning.
charnik@990 99
charnik@990 100 * Strabon endpoint now publishes the URIs of the supported units of
charnik@990 101 measure for use in strdf:distance and geof:distance functions of
charnik@990 102 stSPARQL and GeoSPARQL, respectively. The URIs are those defined by
charnik@990 103 OGC Units of Measure 1.0 specification which may be found at
charnik@990 104 Strabon endpoint publishes
charnik@990 105 the URIs at http://localhost:8080/endpoint/Capabilities.
charnik@990 106
charnik@1004 107 * Created new module with name 'vocab` and artifactId
charnik@1004 108 'strabon-vocabulary` and moved there. Other
charnik@1004 109 vocabularies have been added as well, such as Simple Features, and
charnik@1004 110 GeoSPARQL.
charnik@966 111
charnik@964 112 * Strabon endpoint now publishes the URIs of the supported extension
charnik@964 113 functions for stSPARQL and GeoSPARQL. One should access them by
charnik@964 114 hitting the link http://localhost:8080/endpoint/Capabilities.
charnik@964 115
charnik@932 116 * Support for parsing EPSG URIs in geometry literals with datatype
charnik@932 117 geo:wktLiteral.
charnik@932 118 (bug #33:
charnik@932 119
kallirroi@1273 120 * Endpoint Client now supports querying of Virtuoso and Parliament endpoints.
kallirroi@1273 121
kallirroi@1273 122 * Endpoint Client now supports store and update operations, but only
kallirroi@1273 123 for Strabon Endpoints.
kallirroi@1273 124
kallirroi@1143 125 * GeoSPARQL functions sfCrosses, sfOverlaps, ehOverlaps do not use the
kallirroi@1143 126 ST_Relate PostGIS function (bug #24:
kallirroi@1143 127
kallirroi@1143 128 * All Simple Features functions of GeoSPARQL do not use the ST_Relate
kallirroi@1143 129 PostGIS function
psmeros@1176 130
Konstantina@1174 131 * Added diffTime function. This function performs the difference
Konstantina@1174 132 between two literals of xsd:time datatype and returns a literal of
Konstantina@1174 133 the xsd:time datatype as well.
psmeros@1175 134
psmeros@1175 135 * Added a testsuite package in default branch. Full tester guide can be found
psmeros@1175 136 in README. Among other, most of GeoSPARQL compliance tests
psmeros@1175 137 (, pg. 53) have been
psmeros@1175 138 implemented.
kallirroi@1143 139
sgian@1267 140 * Changed the definition and implementation of strdf:distance function, by
sgian@1267 141 adopting the definition of GeoSPARQL.
sgian@1267 142 (bug #23:
sgian@1267 143
sgian@1268 144 * Changed the definition and implementation of strdf:buffer function, by
sgian@1268 145 adopting the definition of GeoSPARQL.
sgian@1268 146 (bug #35:
sgian@1268 147
sgian@1269 148 * Added geof:distance and geof:buffer functions, which have the same definition
sgian@1269 149 with strdf:distance and strdf:buffer respectively.
sgian@1276 150 (bug #32:
sgian@1269 151
sgian@1270 152 * Added a download button when performing describe and construct queries at the
sgian@1270 153 endpoint.
sgian@1270 154 (bug #38:
sgian@1270 155
sgian@1270 156 * Fixed a bug, where XMLWriter and TSVWriter did not return geometries with the
sgian@1270 157 SRID.
sgian@1270 158 (bug #47:
sgian@1270 159
sgian@1266 160 * Fixed a bug where the GeoSPARQL construct functions did not return the datatype
sgian@1266 161 geo:wktLiteral datatype but strdf:WKT.

charnik@645 164
charnik@853 165 * Version 3.2.8 released.
charnik@853 166
charnik@926 167 * Added support for handling (storing/querying) GeoSPARQL datatypes.
charnik@926 168 (bug #31:
charnik@926 169
charnik@926 170 * Fixed a bug in StoreOp that wouldn't close the connection, neither
charnik@926 171 rollback the transaction upon an exception. This had as a side effect
charnik@926 172 the abnormal termination of StoreOp (through for example the use of
charnik@926 173 Ctrl-C signal) which was leaving the database locked.
charnik@926 174
charnik@926 175 * Fixed bug where spatial aggregates (e.g., union) didn't work as
charnik@926 176 expected when the query didn't contain a `GROUP BY' clause.
charnik@926 177 (bug #22:
charnik@926 178
charnik@926 179 * Updated GeoSPARQL namespaces and fixed function names to comply with
charnik@926 180 the GeoSPARQL specification.

charnik@853 184
kkyzir@801 185 * Version 3.2.7 released.
kkyzir@801 186
ggarbis@854 187 * Add an extension function
ggarbis@854 188 <> for computing the
ggarbis@854 189 span (in milliseconds) between two timestamps.
ggarbis@854 190
ggarbis@854 191 * Added an <endpoint-exec> module. This module builds an executable jar file
ggarbis@854 192 with an embedded Apache Tomcat 7. To create and run the executable jar just
ggarbis@854 193 type:
ggarbis@854 194 $ mvn clean package
ggarbis@854 195 $ java -jar endpoint-exec/target/strabon-endpoint-executable-*.jar
charnik@853 196
charnik@810 197 * Modified strabon script and postgis/monetdb.StoreOP class to get an
charnik@810 198 option for storing a RDF file in a named graph. Moreover, the RDF
charnik@810 199 format of the input RDF file now is given as an option (still, if it
charnik@810 200 is missing, it is assumed that the input is in N-TRIPLES format). The
charnik@810 201 option for the format is -f and the option for the named graph is -g
charnik@810 202 (takes a URI as an argument).
charnik@810 203
kkyzir@801 204 * Modified the names of the stSPARQL extension functions that
kkyzir@801 205 utilize the minimum bounding boxes of the involved geometries.
kkyzir@801 206

charnik@811 208
kkyzir@800 209 * Version 3.2.6 released.
kkyzir@800 210
kkyzir@800 211 * Modified the names of the stSPARQL extension functions to comply
kkyzir@801 212 with the OGC Simple Features Access standard.

charnik@811 215
charnik@645 216 * Version 3.2.5 released.
charnik@645 217
charnik@811 218 * Added support for querying temporal information. This functionality
Konstantina@848 219 may be found in the `temporals' branch.
Konstantina@848 220
charnik@849 221 The datatypes <> and
charnik@849 222 <> are used to
charnik@849 223 represent periods and instants respectively.
Konstantina@848 224
charnik@849 225 The valid time time of triples is represented using quadtruples,
charnik@849 226 with the valid time annotation(instant or period) being the
charnik@849 227 fourth element of the quad. In the same way, temporal triple
charnik@849 228 patterns are used in queries to retrieve the valid time of
charnik@849 229 triples.
Konstantina@848 230
charnik@849 231 Some functions have been renamed (their URIs have changed) to
charnik@849 232 follow the names of the respective relations of Allen's
charnik@849 233 interval algebra and other functions have been added.
Konstantina@848 234
Konstantina@848 235 The following temporal functions are supported:
charnik@849 236 during, periodOverlaps, equalsPeriod, nequalsPeriod, adjacent,
charnik@849 237 before, after, overleft, overright, meets, starts, finishes,
charnik@849 238 period_intersect, period_union, preceding_period, and
charnik@849 239 succeeding_period.
Konstantina@848 240
charnik@759 241 * Changed behaviour of Strabon and Strabon Endpoint for connecting to
charnik@759 242 a spatially-enabled database. Only one instance of Strabon is allowed
charnik@759 243 at a time.
charnik@759 244
charnik@688 245 * Implemented a Java client for Strabon Endpoint. The client should be
charnik@688 246 used only with endpoint versions >=3.2.5. The implementation may be
charnik@688 247 found int the `endpoint-client' submodule of maven. Currently, only
charnik@688 248 querying of Strabon Endpoints is supported.
charnik@688 249
charnik@662 250 * Added support for requesting the capabilities of Strabon Endpoint
charnik@662 251 (fixes Bug #20 <>). See
charnik@662 252 changesets f840796400bf and ?<TBC>? for specific details and how you
charnik@662 253 can determine the capabilities of older endpoints (versions <= 3.2.4).
charnik@662 254
charnik@658 255 * Updated KML writer to include the projected variables of an stSPARQL
charnik@658 256 query in "ExtendedData" and "Data" tags. This is the proper way to
charnik@658 257 do it if we need to convert a KML to a ESRI shapefile and also include
charnik@658 258 such information as attributes for a feature. See related pages from
charnik@658 259 KML specification:
charnik@658 260 <>
charnik@658 261 <>
charnik@658 262
charnik@645 263 * Added user authentication for storing RDF data through Strabon
charnik@662 264 Endpoint. The credentials are specified in
charnik@662 265 WEB-INF/ file.
charnik@645 266
charnik@645 267 * Strabon Endpoints now limits the number of the results to a maximum
charnik@645 268 one. The maximum number is specified in the beans.xml file. This
charnik@645 269 corresponds to parameter "maxLimit". The endpoint script has also been
charnik@645 270 updated correspondingly; the limit can be given using the option "-l".
charnik@645 271 One can disable limiting of query results, by setting the "maxLimit"
charnik@645 272 parameter to 0. Addresses Bug #6
charnik@645 273 (<>).
charnik@645 274
charnik@645 275 * Added "Known Issues" section to README.
charnik@645 276
charnik@645 277 * Added -m (more memory) and -M (much more memory) options in strabon
charnik@645 278 script for out-of-memory exceptions.
charnik@645 279
charnik@849 280 * Fixed Bug #10 (<>). Now
charnik@849 281 KMLWriter handles more geometric types (other than polygons). See
charnik@849 282 changeset 9a3bfee64a39.
charnik@645 283
charnik@645 284 * Menu and navigation in Strabon Endpoint has changed to use jquery.
charnik@645 285 The menu is now populated using the queries placed inside the beans.xml.
charnik@645 286
charnik@645 287 * Added BrowseBean and browse.jsp for browsing the RDF data using the
charnik@645 288 Strabon Endpoint.
