3 * Added support for posing ASK queries.
5 Wed Oct 04 11:55:13 2017 +0300
7 * Bug #82 fixed : Added capability to Endpoint for the user to supply
8 and store his unique Google Maps API Key. The context path of the
9 endpoint is not restricted when a Key is provided. Users that do not
10 supply a key can still run the application as before.
12 Wed Mar 11 21:02:48 2015 Pyravlos Team
14 * Bug #73, modified appendBuffer function to take the srid into
15 consideration even if the argument is a constant (wktLiteral
16 or strdf literal)
18 * Update jar references on scripts used by the debian packaging.
19 Previously these references pointed only (incorrectly) to
22 * Updated package names (since repositories cannot include capital
23 letters + runtime and endpoint-exec must have different names
25 * Version 3.3.1 released.
27 * Bug #58, added script that is invoked my maven to also update the
28 version described in the deb/control file of the runtime and
29 endpoint-exec components.
31 * Related to bug #58, but it generally enhances Strabon; The runtime
32 component has also been debianized. Dependencies are added to
33 /usr/share/jdeb/lib/strabon-runtime. ClassPath and strabon script
34 have also been updated accordingly (strabon-cmd)
36 * Bug #58: Maven creates the debian package conditionally. Use
37 -Ddebian=true in the mvn package command.
39 * Bug #58: Added dependencies - java, postgresql, tomcat. Also, added
40 a strabon-init script that detects the postgis installation path
41 and sets up the template_postgis. Finally the script creates a db
42 called "endpoint" (assuming it does not already exist) that is used
43 for the strabon-endpoint command.
45 * Fixed an issue that returned null SRID when unmarshalling GML geometries if
46 the SRID did not follow one of the supported formats by GML-JTS. To fix that
47 we added a function that handles these cases by reading the userData variable
48 that JTS provides.
50 * Fixed a bug that would return no results when a variable that results
51 from a BIND clause appears in the FILTER or in the projection of a
52 query and is inside a spatial function.
53 (bug #78:
55 * Fixed the precision of the geometry literals in GeoJSON writer. Now,
56 this defaults to the precision model of JTS (equals to 16). Prior to
57 this it was fixed to 4.
59 * Now the GeoJSON writer is aware of the kind of typed literals (e.g.,
60 numeric, boolean, calendar, etc.) and prints the corresponding
61 values according to these types.
63 * Fixed a bug that would not return the correct result or would fail
64 when a spatial function involved a constant and a variable.
65 (bug #74:
67 * Fixed a bug that would not return the correct spatial datatype of a
68 projected geometry literal stored in the database.
69 (bug #71:
71 * Now, geometries expressed in CRS84 and a `geo:wktLiteral' datatype
72 are assigned the correct CRS, i.e., EPSG:4326 with a longitude
73 latitude axis order.
75 * Now, we report a parse error when a constant geometry given in a
76 SELECT or HAVING clause is not well-formed according to the WKT
77 specification.
78 (bug #69:
80 * Function `geof:convexHull' is now supported in a Having clause.
82 * Fixed older implementation of `strdf:distance' that would expect two
83 arguments instead of three when present in a HAVING clause.
85 * Fixed a bug that would cause a class cast exception for grounded
86 expressions with function nesting in the SELECT or HAVING clause.
88 * Fixed a bug in which `postgis:ST_Centroid' did not work in the SELECT
89 clause with input geometries from the database.
91 * Fixed a bug that `geof:getSRID' would return an integer instead of a
92 the URI corrresponding to the CRS that the input geometry was
93 expressed.
94 (bug #32:
96 * Fixed a bug that would raise an exception for queries involving two
97 UNION graph patterns and a projection to a predicate or a URI in
98 general.
99 (bug #53:
101 Wed Sep 17 20:14:12 2014 Pyravlos Team
103 * Version 3.2.10 released.
105 * The test suite of Strabon has now reached a mature level. It
106 contains tests for both stSPARQL and GeoSPARQL query languages and
107 most of the compliance tests covered in the specification of
108 GeoSPARQL (well, only those tests for the components that we have
109 chosen to implement).
111 * The endpoint now parses Accept headers with multiple values and uses
112 the first mimetype corresponding to a valid stSPARQLQueryResultFormat.
113 (bug #64:
115 * The endpoint now registers a handler for SIGTERM signals, so that if
116 it is run from the command-line (endpoint-exec), then the closing of
117 the connection will be ultimately called.
118 (bug #40:
120 * Strabon goes debian v1. the endpoint-exec jar is now given in a .deb
121 format. By dpkg-ing it, one can run a stand alone strabon endpoint
122 locally.
123 (bug #45
125 * Fixed a bug in which Strabon hanged when a unary spatial construct
126 had a ternary spatial construct as argument.
127 (bug #45
129 * Fixed a bug according to which spatial functions in ORDER BY were not
130 evaluated at all.
131 (bug #62:
133 * Fixed a bug according to which spatial boolean functions appearing
134 in the SELECT clause were raising a NULL pointer exception.
135 (bug #34:
137 * Fixed a bug in queries that contain variables that exist inside
138 spatial functions in select and do not exist in the where clause
139 made Strabon throw a NULL pointer exception.
140 (bug #51
142 * Various changes in the interface and behavior of Strabon Endpoint:
143 - Revised the logos and the sample queries.
144 - Results query limit is set to zero (unlimited).
145 - Users can now store RDF data that is present in a file on the
146 client side (the file is uploaded to the server).
147 - Credentials are now required for uploading files or executing
148 UPDATE queries, unless Strabon Endpoint runs locally (localhost).
149 - When viewing the results of queries in HTML, any URI is now an
150 active link to itself. Previously, that URI was being DESCRIBEd
151 and one was being transferred to a page viewing the result of the
152 DESCRIBE query.
153 - The DESCRIBE functionality can now be accessed through the menu bar.
155 * Fixed a bug where strdf:intersection function did not work as an
156 aggregate when used without 'GROUP BY'.
157 (bug #46
160 Sat Oct 19 23:37:23 2013 Pyravlos Team
162 * Version 3.2.9 released.
164 * Added support for the following google chart types: PieChart,
165 AreaChart and ColumnChart to strabon endpoint.
167 * Added Timemap as new results format in Strabon endpoint. This
168 option displays results in a map and a timeline on the same time,
169 using the Timemap js library (
170 The KMLWriter has been extended for that purpose, by transforming
171 dateTime values that are included in the result set into the respective
172 TimeStamp KML primitive (
173 In the "temporals" branch, the values of the strdf:period datatype
174 are converted into the respective KML TimeSpan primitive.
176 * Added extension function <> which is
177 mapped to the ST_Centroid(geometry) extension function of PostGIS.
178 See also: <>.
180 * Added extension function <> which is
181 mapped to the ST_MakeLine(geometry, geometry) extension function of
182 PostGIS. See also: <>.
184 * Added PostGIS vocabulary class.
186 * Added support of all SPARQL result types provided by Sesame (json,
187 xml, csv, tsv, binary). To get the respective writer, just prepend the
188 string "SPARQL/", e.g., "SPARQL/JSON". This is to ensure that we
189 support all SPARQL result formats of the SPARQL Protocol.
191 * Fixed a bug where a non-implemented extension function would make
192 Strabon throw a NULL pointer exception. Now we get away with it
193 through a warning.
195 * Strabon endpoint now publishes the URIs of the supported units of
196 measure for use in strdf:distance and geof:distance functions of
197 stSPARQL and GeoSPARQL, respectively. The URIs are those defined by
198 OGC Units of Measure 1.0 specification which may be found at
199 Strabon endpoint publishes
200 the URIs at http://localhost:8080/endpoint/Capabilities.
202 * Created new module with name 'vocab` and artifactId
203 'strabon-vocabulary` and moved there. Other
204 vocabularies have been added as well, such as Simple Features, and
205 GeoSPARQL.
207 * Strabon endpoint now publishes the URIs of the supported extension
208 functions for stSPARQL and GeoSPARQL. One should access them by
209 hitting the link http://localhost:8080/endpoint/Capabilities.
211 * Support for parsing EPSG URIs in geometry literals with datatype
212 geo:wktLiteral.
213 (bug #33:
215 * Endpoint Client now supports querying of Virtuoso and Parliament endpoints.
217 * Endpoint Client now supports store and update operations, but only
218 for Strabon Endpoints.
220 * GeoSPARQL functions sfCrosses, sfOverlaps, ehOverlaps do not use the
221 ST_Relate PostGIS function (bug #24:
223 * All Simple Features functions of GeoSPARQL do not use the ST_Relate
224 PostGIS function
226 * Added diffTime function. This function performs the difference
227 between two literals of xsd:time datatype and returns a literal of
228 the xsd:time datatype as well.
230 * Added a testsuite package in default branch. Full tester guide can be found
231 in README. Among other, most of GeoSPARQL compliance tests
232 (, pg. 53) have been
233 implemented.
235 * Changed the definition and implementation of strdf:distance function, by
236 adopting the definition of GeoSPARQL.
237 (bug #23:
239 * Changed the definition and implementation of strdf:buffer function, by
240 adopting the definition of GeoSPARQL.
241 (bug #35:
243 * Added geof:distance and geof:buffer functions, which have the same definition
244 with strdf:distance and strdf:buffer respectively.
245 (bug #32:
247 * Added a download button when performing describe and construct queries at the
248 endpoint.
249 (bug #38:
251 * Fixed a bug, where XMLWriter and TSVWriter did not return geometries with the
252 SRID.
253 (bug #47:
255 * Fixed a bug where the GeoSPARQL construct functions did not return the datatype
256 geo:wktLiteral datatype but strdf:WKT.
258 Tue Mar 26 13:28:26 2013 Pyravlos Team
260 * Version 3.2.8 released.
262 * Added support for handling (storing/querying) GeoSPARQL datatypes.
263 (bug #31:
265 * Fixed a bug in StoreOp that wouldn't close the connection, neither
266 rollback the transaction upon an exception. This had as a side effect
267 the abnormal termination of StoreOp (through for example the use of
268 Ctrl-C signal) which was leaving the database locked.
270 * Fixed bug where spatial aggregates (e.g., union) didn't work as
271 expected when the query didn't contain a `GROUP BY' clause.
272 (bug #22:
274 * Updated GeoSPARQL namespaces and fixed function names to comply with
275 the GeoSPARQL specification.
276 (bug #25:
278 Wed Jan 09 18:06:41 2013 Pyravlos Team
280 * Version 3.2.7 released.
282 * Add an extension function
283 <> for computing the
284 span (in milliseconds) between two timestamps.
286 * Added an <endpoint-exec> module. This module builds an executable jar file
287 with an embedded Apache Tomcat 7. To create and run the executable jar just
288 type:
289 $ mvn clean package
290 $ java -jar endpoint-exec/target/strabon-endpoint-executable-*.jar
292 * Modified strabon script and postgis/monetdb.StoreOP class to get an
293 option for storing a RDF file in a named graph. Moreover, the RDF
294 format of the input RDF file now is given as an option (still, if it
295 is missing, it is assumed that the input is in N-TRIPLES format). The
296 option for the format is -f and the option for the named graph is -g
297 (takes a URI as an argument).
299 * Modified the names of the stSPARQL extension functions that
300 utilize the minimum bounding boxes of the involved geometries.
302 Tue Dec 11 19:33:45 2012 Pyravlos Team
304 * Version 3.2.6 released.
306 * Modified the names of the stSPARQL extension functions to comply
307 with the OGC Simple Features Access standard.
309 Tue Dec 11 00:11:43 2012 Pyravlos Team
311 * Version 3.2.5 released.
313 * Added support for querying temporal information. This functionality
314 may be found in the `temporals' branch.
316 The datatypes <> and
317 <> are used to
318 represent periods and instants respectively.
320 The valid time time of triples is represented using quadtruples,
321 with the valid time annotation(instant or period) being the
322 fourth element of the quad. In the same way, temporal triple
323 patterns are used in queries to retrieve the valid time of
324 triples.
326 Some functions have been renamed (their URIs have changed) to
327 follow the names of the respective relations of Allen's
328 interval algebra and other functions have been added.
330 The following temporal functions are supported:
331 during, periodOverlaps, equalsPeriod, nequalsPeriod, adjacent,
332 before, after, overleft, overright, meets, starts, finishes,
333 period_intersect, period_union, preceding_period, and
334 succeeding_period.
336 * Changed behaviour of Strabon and Strabon Endpoint for connecting to
337 a spatially-enabled database. Only one instance of Strabon is allowed
338 at a time.
340 * Implemented a Java client for Strabon Endpoint. The client should be
341 used only with endpoint versions >=3.2.5. The implementation may be
342 found int the `endpoint-client' submodule of maven. Currently, only
343 querying of Strabon Endpoints is supported.
345 * Added support for requesting the capabilities of Strabon Endpoint
346 (fixes Bug #20 <>). See
347 changesets f840796400bf and ?<TBC>? for specific details and how you
348 can determine the capabilities of older endpoints (versions <= 3.2.4).
350 * Updated KML writer to include the projected variables of an stSPARQL
351 query in "ExtendedData" and "Data" tags. This is the proper way to
352 do it if we need to convert a KML to a ESRI shapefile and also include
353 such information as attributes for a feature. See related pages from
354 KML specification:
355 <>
356 <>
358 * Added user authentication for storing RDF data through Strabon
359 Endpoint. The credentials are specified in
360 WEB-INF/ file.
362 * Strabon Endpoints now limits the number of the results to a maximum
363 one. The maximum number is specified in the beans.xml file. This
364 corresponds to parameter "maxLimit". The endpoint script has also been
365 updated correspondingly; the limit can be given using the option "-l".
366 One can disable limiting of query results, by setting the "maxLimit"
367 parameter to 0. Addresses Bug #6
368 (<>).
370 * Added "Known Issues" section to README.
372 * Added -m (more memory) and -M (much more memory) options in strabon
373 script for out-of-memory exceptions.
375 * Fixed Bug #10 (<>). Now
376 KMLWriter handles more geometric types (other than polygons). See
377 changeset 9a3bfee64a39.
379 * Menu and navigation in Strabon Endpoint has changed to use jquery.
380 The menu is now populated using the queries placed inside the beans.xml.
382 * Added BrowseBean and browse.jsp for browsing the RDF data using the
383 Strabon Endpoint.
