1 * Fixed the precision of the geometry literals in GeoJSON writer. Now,
2 this defaults to the precision model of JTS (equals to 16). Prior to
3 this it was fixed to 4.
5 * Now the GeoJSON writer is aware of the kind of typed literals (e.g.,
6 numeric, boolean, calendar, etc.) and prints the corresponding
7 values according to these types.
9 * Fixed a bug that would not return the correct result or would fail
10 when a spatial function involved a constant and a variable.
11 (bug #74:
13 * Fixed a bug that would not return the correct spatial datatype of a
14 projected geometry literal stored in the database.
15 (bug #71:
17 * Now, geometries expressed in CRS84 and a `geo:wktLiteral' datatype
18 are assigned the correct CRS, i.e., EPSG:4326 with a longitude
19 latitude axis order.
21 * Now, we report a parse error when a constant geometry given in a
22 SELECT or HAVING clause is not well-formed according to the WKT
23 specification.
24 (bug #69:
26 * Function `geof:convexHull' is now supported in a Having clause.
28 * Fixed older implementation of `strdf:distance' that would expect two
29 arguments instead of three when present in a HAVING clause.
31 * Fixed a bug that would cause a class cast exception for grounded
32 expressions with function nesting in the SELECT or HAVING clause.
34 * Fixed a bug in which `postgis:ST_Centroid' did not work in the SELECT
35 clause with input geometries from the database.
37 * Fixed a bug that `geof:getSRID' would return an integer instead of a
38 the URI corrresponding to the CRS that the input geometry was
39 expressed.
40 (bug #32:
42 * Fixed a bug that would raise an exception for queries involving two
43 UNION graph patterns and a projection to a predicate or a URI in
44 general.
45 (bug #53:
47 Wed Sep 17 20:14:12 2014 Pyravlos Team
49 * Version 3.2.10 released.
51 * The test suite of Strabon has now reached a mature level. It
52 contains tests for both stSPARQL and GeoSPARQL query languages and
53 most of the compliance tests covered in the specification of
54 GeoSPARQL (well, only those tests for the components that we have
55 chosen to implement).
57 * The endpoint now parses Accept headers with multiple values and uses
58 the first mimetype corresponding to a valid stSPARQLQueryResultFormat.
59 (bug #64:
61 * The endpoint now registers a handler for SIGTERM signals, so that if
62 it is run from the command-line (endpoint-exec), then the closing of
63 the connection will be ultimately called.
64 (bug #40:
66 * Strabon goes debian v1. the endpoint-exec jar is now given in a .deb
67 format. By dpkg-ing it, one can run a stand alone strabon endpoint
68 locally.
69 (bug #45
71 * Fixed a bug in which Strabon hanged when a unary spatial construct
72 had a ternary spatial construct as argument.
73 (bug #45
75 * Fixed a bug according to which spatial functions in ORDER BY were not
76 evaluated at all.
77 (bug #62:
79 * Fixed a bug according to which spatial boolean functions appearing
80 in the SELECT clause were raising a NULL pointer exception.
81 (bug #34:
83 * Fixed a bug in queries that contain variables that exist inside
84 spatial functions in select and do not exist in the where clause
85 made Strabon throw a NULL pointer exception.
86 (bug #51
88 * Various changes in the interface and behavior of Strabon Endpoint:
89 - Revised the logos and the sample queries.
90 - Results query limit is set to zero (unlimited).
91 - Users can now store RDF data that is present in a file on the
92 client side (the file is uploaded to the server).
93 - Credentials are now required for uploading files or executing
94 UPDATE queries, unless Strabon Endpoint runs locally (localhost).
95 - When viewing the results of queries in HTML, any URI is now an
96 active link to itself. Previously, that URI was being DESCRIBEd
97 and one was being transferred to a page viewing the result of the
98 DESCRIBE query.
99 - The DESCRIBE functionality can now be accessed through the menu bar.
101 * Fixed a bug where strdf:intersection function did not work as an
102 aggregate when used without 'GROUP BY'.
103 (bug #46
106 Sat Oct 19 23:37:23 2013 Pyravlos Team
108 * Version 3.2.9 released.
110 * Added support for the following google chart types: PieChart,
111 AreaChart and ColumnChart to strabon endpoint.
113 * Added Timemap as new results format in Strabon endpoint. This
114 option displays results in a map and a timeline on the same time,
115 using the Timemap js library (
116 The KMLWriter has been extended for that purpose, by transforming
117 dateTime values that are included in the result set into the respective
118 TimeStamp KML primitive (
119 In the "temporals" branch, the values of the strdf:period datatype
120 are converted into the respective KML TimeSpan primitive.
122 * Added extension function <> which is
123 mapped to the ST_Centroid(geometry) extension function of PostGIS.
124 See also: <>.
126 * Added extension function <> which is
127 mapped to the ST_MakeLine(geometry, geometry) extension function of
128 PostGIS. See also: <>.
130 * Added PostGIS vocabulary class.
132 * Added support of all SPARQL result types provided by Sesame (json,
133 xml, csv, tsv, binary). To get the respective writer, just prepend the
134 string "SPARQL/", e.g., "SPARQL/JSON". This is to ensure that we
135 support all SPARQL result formats of the SPARQL Protocol.
137 * Fixed a bug where a non-implemented extension function would make
138 Strabon throw a NULL pointer exception. Now we get away with it
139 through a warning.
141 * Strabon endpoint now publishes the URIs of the supported units of
142 measure for use in strdf:distance and geof:distance functions of
143 stSPARQL and GeoSPARQL, respectively. The URIs are those defined by
144 OGC Units of Measure 1.0 specification which may be found at
145 Strabon endpoint publishes
146 the URIs at http://localhost:8080/endpoint/Capabilities.
148 * Created new module with name 'vocab` and artifactId
149 'strabon-vocabulary` and moved there. Other
150 vocabularies have been added as well, such as Simple Features, and
151 GeoSPARQL.
153 * Strabon endpoint now publishes the URIs of the supported extension
154 functions for stSPARQL and GeoSPARQL. One should access them by
155 hitting the link http://localhost:8080/endpoint/Capabilities.
157 * Support for parsing EPSG URIs in geometry literals with datatype
158 geo:wktLiteral.
159 (bug #33:
161 * Endpoint Client now supports querying of Virtuoso and Parliament endpoints.
163 * Endpoint Client now supports store and update operations, but only
164 for Strabon Endpoints.
166 * GeoSPARQL functions sfCrosses, sfOverlaps, ehOverlaps do not use the
167 ST_Relate PostGIS function (bug #24:
169 * All Simple Features functions of GeoSPARQL do not use the ST_Relate
170 PostGIS function
172 * Added diffTime function. This function performs the difference
173 between two literals of xsd:time datatype and returns a literal of
174 the xsd:time datatype as well.
176 * Added a testsuite package in default branch. Full tester guide can be found
177 in README. Among other, most of GeoSPARQL compliance tests
178 (, pg. 53) have been
179 implemented.
181 * Changed the definition and implementation of strdf:distance function, by
182 adopting the definition of GeoSPARQL.
183 (bug #23:
185 * Changed the definition and implementation of strdf:buffer function, by
186 adopting the definition of GeoSPARQL.
187 (bug #35:
189 * Added geof:distance and geof:buffer functions, which have the same definition
190 with strdf:distance and strdf:buffer respectively.
191 (bug #32:
193 * Added a download button when performing describe and construct queries at the
194 endpoint.
195 (bug #38:
197 * Fixed a bug, where XMLWriter and TSVWriter did not return geometries with the
198 SRID.
199 (bug #47:
201 * Fixed a bug where the GeoSPARQL construct functions did not return the datatype
202 geo:wktLiteral datatype but strdf:WKT.
204 Tue Mar 26 13:28:26 2013 Pyravlos Team
206 * Version 3.2.8 released.
208 * Added support for handling (storing/querying) GeoSPARQL datatypes.
209 (bug #31:
211 * Fixed a bug in StoreOp that wouldn't close the connection, neither
212 rollback the transaction upon an exception. This had as a side effect
213 the abnormal termination of StoreOp (through for example the use of
214 Ctrl-C signal) which was leaving the database locked.
216 * Fixed bug where spatial aggregates (e.g., union) didn't work as
217 expected when the query didn't contain a `GROUP BY' clause.
218 (bug #22:
220 * Updated GeoSPARQL namespaces and fixed function names to comply with
221 the GeoSPARQL specification.
222 (bug #25:
224 Wed Jan 09 18:06:41 2013 Pyravlos Team
226 * Version 3.2.7 released.
228 * Add an extension function
229 <> for computing the
230 span (in milliseconds) between two timestamps.
232 * Added an <endpoint-exec> module. This module builds an executable jar file
233 with an embedded Apache Tomcat 7. To create and run the executable jar just
234 type:
235 $ mvn clean package
236 $ java -jar endpoint-exec/target/strabon-endpoint-executable-*.jar
238 * Modified strabon script and postgis/monetdb.StoreOP class to get an
239 option for storing a RDF file in a named graph. Moreover, the RDF
240 format of the input RDF file now is given as an option (still, if it
241 is missing, it is assumed that the input is in N-TRIPLES format). The
242 option for the format is -f and the option for the named graph is -g
243 (takes a URI as an argument).
245 * Modified the names of the stSPARQL extension functions that
246 utilize the minimum bounding boxes of the involved geometries.
248 Tue Dec 11 19:33:45 2012 Pyravlos Team
250 * Version 3.2.6 released.
252 * Modified the names of the stSPARQL extension functions to comply
253 with the OGC Simple Features Access standard.
255 Tue Dec 11 00:11:43 2012 Pyravlos Team
257 * Version 3.2.5 released.
259 * Added support for querying temporal information. This functionality
260 may be found in the `temporals' branch.
262 The datatypes <> and
263 <> are used to
264 represent periods and instants respectively.
266 The valid time time of triples is represented using quadtruples,
267 with the valid time annotation(instant or period) being the
268 fourth element of the quad. In the same way, temporal triple
269 patterns are used in queries to retrieve the valid time of
270 triples.
272 Some functions have been renamed (their URIs have changed) to
273 follow the names of the respective relations of Allen's
274 interval algebra and other functions have been added.
276 The following temporal functions are supported:
277 during, periodOverlaps, equalsPeriod, nequalsPeriod, adjacent,
278 before, after, overleft, overright, meets, starts, finishes,
279 period_intersect, period_union, preceding_period, and
280 succeeding_period.
282 * Changed behaviour of Strabon and Strabon Endpoint for connecting to
283 a spatially-enabled database. Only one instance of Strabon is allowed
284 at a time.
286 * Implemented a Java client for Strabon Endpoint. The client should be
287 used only with endpoint versions >=3.2.5. The implementation may be
288 found int the `endpoint-client' submodule of maven. Currently, only
289 querying of Strabon Endpoints is supported.
291 * Added support for requesting the capabilities of Strabon Endpoint
292 (fixes Bug #20 <>). See
293 changesets f840796400bf and ?<TBC>? for specific details and how you
294 can determine the capabilities of older endpoints (versions <= 3.2.4).
296 * Updated KML writer to include the projected variables of an stSPARQL
297 query in "ExtendedData" and "Data" tags. This is the proper way to
298 do it if we need to convert a KML to a ESRI shapefile and also include
299 such information as attributes for a feature. See related pages from
300 KML specification:
301 <>
302 <>
304 * Added user authentication for storing RDF data through Strabon
305 Endpoint. The credentials are specified in
306 WEB-INF/ file.
308 * Strabon Endpoints now limits the number of the results to a maximum
309 one. The maximum number is specified in the beans.xml file. This
310 corresponds to parameter "maxLimit". The endpoint script has also been
311 updated correspondingly; the limit can be given using the option "-l".
312 One can disable limiting of query results, by setting the "maxLimit"
313 parameter to 0. Addresses Bug #6
314 (<>).
316 * Added "Known Issues" section to README.
318 * Added -m (more memory) and -M (much more memory) options in strabon
319 script for out-of-memory exceptions.
321 * Fixed Bug #10 (<>). Now
322 KMLWriter handles more geometric types (other than polygons). See
323 changeset 9a3bfee64a39.
325 * Menu and navigation in Strabon Endpoint has changed to use jquery.
326 The menu is now populated using the queries placed inside the beans.xml.
328 * Added BrowseBean and browse.jsp for browsing the RDF data using the
329 Strabon Endpoint.
