1 * Bug #58, added script that is invoked my maven to also update the
2 version described in the deb/control file of the runtime and
3 endpoint-exec components.
5 * Related to bug #58, but it generally enhances Strabon; The runtime
6 component has also been debianized. Dependencies are added to
7 /usr/share/jdeb/lib/strabon-runtime. ClassPath and strabon script
8 have also been updated accordingly (strabon-cmd)
10 * Bug #58: Maven creates the debian package conditionally. Use
11 -Ddebian=true in the mvn package command.
13 * Bug #58: Added dependencies - java, postgresql, tomcat. Also, added
14 a strabon-init script that detects the postgis installation path
15 and sets up the template_postgis. Finally the script creates a db
16 called "endpoint" (assuming it does not already exist) that is used
17 for the strabon-endpoint command.
19 * Fixed an issue that returned null SRID when unmarshalling GML geometries if
20 the SRID did not follow one of the supported formats by GML-JTS. To fix that
21 we added a function that handles these cases by reading the userData variable
22 that JTS provides.
24 * Fixed a bug that would return no results when a variable that results
25 from a BIND clause appears in the FILTER or in the projection of a
26 query and is inside a spatial function.
27 (bug #78:
29 * Fixed the precision of the geometry literals in GeoJSON writer. Now,
30 this defaults to the precision model of JTS (equals to 16). Prior to
31 this it was fixed to 4.
33 * Now the GeoJSON writer is aware of the kind of typed literals (e.g.,
34 numeric, boolean, calendar, etc.) and prints the corresponding
35 values according to these types.
37 * Fixed a bug that would not return the correct result or would fail
38 when a spatial function involved a constant and a variable.
39 (bug #74:
41 * Fixed a bug that would not return the correct spatial datatype of a
42 projected geometry literal stored in the database.
43 (bug #71:
45 * Now, geometries expressed in CRS84 and a `geo:wktLiteral' datatype
46 are assigned the correct CRS, i.e., EPSG:4326 with a longitude
47 latitude axis order.
49 * Now, we report a parse error when a constant geometry given in a
50 SELECT or HAVING clause is not well-formed according to the WKT
51 specification.
52 (bug #69:
54 * Function `geof:convexHull' is now supported in a Having clause.
56 * Fixed older implementation of `strdf:distance' that would expect two
57 arguments instead of three when present in a HAVING clause.
59 * Fixed a bug that would cause a class cast exception for grounded
60 expressions with function nesting in the SELECT or HAVING clause.
62 * Fixed a bug in which `postgis:ST_Centroid' did not work in the SELECT
63 clause with input geometries from the database.
65 * Fixed a bug that `geof:getSRID' would return an integer instead of a
66 the URI corrresponding to the CRS that the input geometry was
67 expressed.
68 (bug #32:
70 * Fixed a bug that would raise an exception for queries involving two
71 UNION graph patterns and a projection to a predicate or a URI in
72 general.
73 (bug #53:
75 Wed Sep 17 20:14:12 2014 Pyravlos Team
77 * Version 3.2.10 released.
79 * The test suite of Strabon has now reached a mature level. It
80 contains tests for both stSPARQL and GeoSPARQL query languages and
81 most of the compliance tests covered in the specification of
82 GeoSPARQL (well, only those tests for the components that we have
83 chosen to implement).
85 * The endpoint now parses Accept headers with multiple values and uses
86 the first mimetype corresponding to a valid stSPARQLQueryResultFormat.
87 (bug #64:
89 * The endpoint now registers a handler for SIGTERM signals, so that if
90 it is run from the command-line (endpoint-exec), then the closing of
91 the connection will be ultimately called.
92 (bug #40:
94 * Strabon goes debian v1. the endpoint-exec jar is now given in a .deb
95 format. By dpkg-ing it, one can run a stand alone strabon endpoint
96 locally.
97 (bug #45
99 * Fixed a bug in which Strabon hanged when a unary spatial construct
100 had a ternary spatial construct as argument.
101 (bug #45
103 * Fixed a bug according to which spatial functions in ORDER BY were not
104 evaluated at all.
105 (bug #62:
107 * Fixed a bug according to which spatial boolean functions appearing
108 in the SELECT clause were raising a NULL pointer exception.
109 (bug #34:
111 * Fixed a bug in queries that contain variables that exist inside
112 spatial functions in select and do not exist in the where clause
113 made Strabon throw a NULL pointer exception.
114 (bug #51
116 * Various changes in the interface and behavior of Strabon Endpoint:
117 - Revised the logos and the sample queries.
118 - Results query limit is set to zero (unlimited).
119 - Users can now store RDF data that is present in a file on the
120 client side (the file is uploaded to the server).
121 - Credentials are now required for uploading files or executing
122 UPDATE queries, unless Strabon Endpoint runs locally (localhost).
123 - When viewing the results of queries in HTML, any URI is now an
124 active link to itself. Previously, that URI was being DESCRIBEd
125 and one was being transferred to a page viewing the result of the
126 DESCRIBE query.
127 - The DESCRIBE functionality can now be accessed through the menu bar.
129 * Fixed a bug where strdf:intersection function did not work as an
130 aggregate when used without 'GROUP BY'.
131 (bug #46
134 Sat Oct 19 23:37:23 2013 Pyravlos Team
136 * Version 3.2.9 released.
138 * Added support for the following google chart types: PieChart,
139 AreaChart and ColumnChart to strabon endpoint.
141 * Added Timemap as new results format in Strabon endpoint. This
142 option displays results in a map and a timeline on the same time,
143 using the Timemap js library (
144 The KMLWriter has been extended for that purpose, by transforming
145 dateTime values that are included in the result set into the respective
146 TimeStamp KML primitive (
147 In the "temporals" branch, the values of the strdf:period datatype
148 are converted into the respective KML TimeSpan primitive.
150 * Added extension function <> which is
151 mapped to the ST_Centroid(geometry) extension function of PostGIS.
152 See also: <>.
154 * Added extension function <> which is
155 mapped to the ST_MakeLine(geometry, geometry) extension function of
156 PostGIS. See also: <>.
158 * Added PostGIS vocabulary class.
160 * Added support of all SPARQL result types provided by Sesame (json,
161 xml, csv, tsv, binary). To get the respective writer, just prepend the
162 string "SPARQL/", e.g., "SPARQL/JSON". This is to ensure that we
163 support all SPARQL result formats of the SPARQL Protocol.
165 * Fixed a bug where a non-implemented extension function would make
166 Strabon throw a NULL pointer exception. Now we get away with it
167 through a warning.
169 * Strabon endpoint now publishes the URIs of the supported units of
170 measure for use in strdf:distance and geof:distance functions of
171 stSPARQL and GeoSPARQL, respectively. The URIs are those defined by
172 OGC Units of Measure 1.0 specification which may be found at
173 Strabon endpoint publishes
174 the URIs at http://localhost:8080/endpoint/Capabilities.
176 * Created new module with name 'vocab` and artifactId
177 'strabon-vocabulary` and moved there. Other
178 vocabularies have been added as well, such as Simple Features, and
179 GeoSPARQL.
181 * Strabon endpoint now publishes the URIs of the supported extension
182 functions for stSPARQL and GeoSPARQL. One should access them by
183 hitting the link http://localhost:8080/endpoint/Capabilities.
185 * Support for parsing EPSG URIs in geometry literals with datatype
186 geo:wktLiteral.
187 (bug #33:
189 * Endpoint Client now supports querying of Virtuoso and Parliament endpoints.
191 * Endpoint Client now supports store and update operations, but only
192 for Strabon Endpoints.
194 * GeoSPARQL functions sfCrosses, sfOverlaps, ehOverlaps do not use the
195 ST_Relate PostGIS function (bug #24:
197 * All Simple Features functions of GeoSPARQL do not use the ST_Relate
198 PostGIS function
200 * Added diffTime function. This function performs the difference
201 between two literals of xsd:time datatype and returns a literal of
202 the xsd:time datatype as well.
204 * Added a testsuite package in default branch. Full tester guide can be found
205 in README. Among other, most of GeoSPARQL compliance tests
206 (, pg. 53) have been
207 implemented.
209 * Changed the definition and implementation of strdf:distance function, by
210 adopting the definition of GeoSPARQL.
211 (bug #23:
213 * Changed the definition and implementation of strdf:buffer function, by
214 adopting the definition of GeoSPARQL.
215 (bug #35:
217 * Added geof:distance and geof:buffer functions, which have the same definition
218 with strdf:distance and strdf:buffer respectively.
219 (bug #32:
221 * Added a download button when performing describe and construct queries at the
222 endpoint.
223 (bug #38:
225 * Fixed a bug, where XMLWriter and TSVWriter did not return geometries with the
226 SRID.
227 (bug #47:
229 * Fixed a bug where the GeoSPARQL construct functions did not return the datatype
230 geo:wktLiteral datatype but strdf:WKT.
232 Tue Mar 26 13:28:26 2013 Pyravlos Team
234 * Version 3.2.8 released.
236 * Added support for handling (storing/querying) GeoSPARQL datatypes.
237 (bug #31:
239 * Fixed a bug in StoreOp that wouldn't close the connection, neither
240 rollback the transaction upon an exception. This had as a side effect
241 the abnormal termination of StoreOp (through for example the use of
242 Ctrl-C signal) which was leaving the database locked.
244 * Fixed bug where spatial aggregates (e.g., union) didn't work as
245 expected when the query didn't contain a `GROUP BY' clause.
246 (bug #22:
248 * Updated GeoSPARQL namespaces and fixed function names to comply with
249 the GeoSPARQL specification.
250 (bug #25:
252 Wed Jan 09 18:06:41 2013 Pyravlos Team
254 * Version 3.2.7 released.
256 * Add an extension function
257 <> for computing the
258 span (in milliseconds) between two timestamps.
260 * Added an <endpoint-exec> module. This module builds an executable jar file
261 with an embedded Apache Tomcat 7. To create and run the executable jar just
262 type:
263 $ mvn clean package
264 $ java -jar endpoint-exec/target/strabon-endpoint-executable-*.jar
266 * Modified strabon script and postgis/monetdb.StoreOP class to get an
267 option for storing a RDF file in a named graph. Moreover, the RDF
268 format of the input RDF file now is given as an option (still, if it
269 is missing, it is assumed that the input is in N-TRIPLES format). The
270 option for the format is -f and the option for the named graph is -g
271 (takes a URI as an argument).
273 * Modified the names of the stSPARQL extension functions that
274 utilize the minimum bounding boxes of the involved geometries.
276 Tue Dec 11 19:33:45 2012 Pyravlos Team
278 * Version 3.2.6 released.
280 * Modified the names of the stSPARQL extension functions to comply
281 with the OGC Simple Features Access standard.
283 Tue Dec 11 00:11:43 2012 Pyravlos Team
285 * Version 3.2.5 released.
287 * Added support for querying temporal information. This functionality
288 may be found in the `temporals' branch.
290 The datatypes <> and
291 <> are used to
292 represent periods and instants respectively.
294 The valid time time of triples is represented using quadtruples,
295 with the valid time annotation(instant or period) being the
296 fourth element of the quad. In the same way, temporal triple
297 patterns are used in queries to retrieve the valid time of
298 triples.
300 Some functions have been renamed (their URIs have changed) to
301 follow the names of the respective relations of Allen's
302 interval algebra and other functions have been added.
304 The following temporal functions are supported:
305 during, periodOverlaps, equalsPeriod, nequalsPeriod, adjacent,
306 before, after, overleft, overright, meets, starts, finishes,
307 period_intersect, period_union, preceding_period, and
308 succeeding_period.
310 * Changed behaviour of Strabon and Strabon Endpoint for connecting to
311 a spatially-enabled database. Only one instance of Strabon is allowed
312 at a time.
314 * Implemented a Java client for Strabon Endpoint. The client should be
315 used only with endpoint versions >=3.2.5. The implementation may be
316 found int the `endpoint-client' submodule of maven. Currently, only
317 querying of Strabon Endpoints is supported.
319 * Added support for requesting the capabilities of Strabon Endpoint
320 (fixes Bug #20 <>). See
321 changesets f840796400bf and ?<TBC>? for specific details and how you
322 can determine the capabilities of older endpoints (versions <= 3.2.4).
324 * Updated KML writer to include the projected variables of an stSPARQL
325 query in "ExtendedData" and "Data" tags. This is the proper way to
326 do it if we need to convert a KML to a ESRI shapefile and also include
327 such information as attributes for a feature. See related pages from
328 KML specification:
329 <>
330 <>
332 * Added user authentication for storing RDF data through Strabon
333 Endpoint. The credentials are specified in
334 WEB-INF/ file.
336 * Strabon Endpoints now limits the number of the results to a maximum
337 one. The maximum number is specified in the beans.xml file. This
338 corresponds to parameter "maxLimit". The endpoint script has also been
339 updated correspondingly; the limit can be given using the option "-l".
340 One can disable limiting of query results, by setting the "maxLimit"
341 parameter to 0. Addresses Bug #6
342 (<>).
344 * Added "Known Issues" section to README.
346 * Added -m (more memory) and -M (much more memory) options in strabon
347 script for out-of-memory exceptions.
349 * Fixed Bug #10 (<>). Now
350 KMLWriter handles more geometric types (other than polygons). See
351 changeset 9a3bfee64a39.
353 * Menu and navigation in Strabon Endpoint has changed to use jquery.
354 The menu is now populated using the queries placed inside the beans.xml.
356 * Added BrowseBean and browse.jsp for browsing the RDF data using the
357 Strabon Endpoint.
