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 a bug that would return no results when a variable that results
20 from a BIND clause appears in the FILTER or in the projection of a
21 query and is inside a spatial function.
22 (bug #78:
24 * Fixed the precision of the geometry literals in GeoJSON writer. Now,
25 this defaults to the precision model of JTS (equals to 16). Prior to
26 this it was fixed to 4.
28 * Now the GeoJSON writer is aware of the kind of typed literals (e.g.,
29 numeric, boolean, calendar, etc.) and prints the corresponding
30 values according to these types.
32 * Fixed a bug that would not return the correct result or would fail
33 when a spatial function involved a constant and a variable.
34 (bug #74:
36 * Fixed a bug that would not return the correct spatial datatype of a
37 projected geometry literal stored in the database.
38 (bug #71:
40 * Now, geometries expressed in CRS84 and a `geo:wktLiteral' datatype
41 are assigned the correct CRS, i.e., EPSG:4326 with a longitude
42 latitude axis order.
44 * Now, we report a parse error when a constant geometry given in a
45 SELECT or HAVING clause is not well-formed according to the WKT
46 specification.
47 (bug #69:
49 * Function `geof:convexHull' is now supported in a Having clause.
51 * Fixed older implementation of `strdf:distance' that would expect two
52 arguments instead of three when present in a HAVING clause.
54 * Fixed a bug that would cause a class cast exception for grounded
55 expressions with function nesting in the SELECT or HAVING clause.
57 * Fixed a bug in which `postgis:ST_Centroid' did not work in the SELECT
58 clause with input geometries from the database.
60 * Fixed a bug that `geof:getSRID' would return an integer instead of a
61 the URI corrresponding to the CRS that the input geometry was
62 expressed.
63 (bug #32:
65 * Fixed a bug that would raise an exception for queries involving two
66 UNION graph patterns and a projection to a predicate or a URI in
67 general.
68 (bug #53:
70 Wed Sep 17 20:14:12 2014 Pyravlos Team
72 * Version 3.2.10 released.
74 * The test suite of Strabon has now reached a mature level. It
75 contains tests for both stSPARQL and GeoSPARQL query languages and
76 most of the compliance tests covered in the specification of
77 GeoSPARQL (well, only those tests for the components that we have
78 chosen to implement).
80 * The endpoint now parses Accept headers with multiple values and uses
81 the first mimetype corresponding to a valid stSPARQLQueryResultFormat.
82 (bug #64:
84 * The endpoint now registers a handler for SIGTERM signals, so that if
85 it is run from the command-line (endpoint-exec), then the closing of
86 the connection will be ultimately called.
87 (bug #40:
89 * Strabon goes debian v1. the endpoint-exec jar is now given in a .deb
90 format. By dpkg-ing it, one can run a stand alone strabon endpoint
91 locally.
92 (bug #45
94 * Fixed a bug in which Strabon hanged when a unary spatial construct
95 had a ternary spatial construct as argument.
96 (bug #45
98 * Fixed a bug according to which spatial functions in ORDER BY were not
99 evaluated at all.
100 (bug #62:
102 * Fixed a bug according to which spatial boolean functions appearing
103 in the SELECT clause were raising a NULL pointer exception.
104 (bug #34:
106 * Fixed a bug in queries that contain variables that exist inside
107 spatial functions in select and do not exist in the where clause
108 made Strabon throw a NULL pointer exception.
109 (bug #51
111 * Various changes in the interface and behavior of Strabon Endpoint:
112 - Revised the logos and the sample queries.
113 - Results query limit is set to zero (unlimited).
114 - Users can now store RDF data that is present in a file on the
115 client side (the file is uploaded to the server).
116 - Credentials are now required for uploading files or executing
117 UPDATE queries, unless Strabon Endpoint runs locally (localhost).
118 - When viewing the results of queries in HTML, any URI is now an
119 active link to itself. Previously, that URI was being DESCRIBEd
120 and one was being transferred to a page viewing the result of the
121 DESCRIBE query.
122 - The DESCRIBE functionality can now be accessed through the menu bar.
124 * Fixed a bug where strdf:intersection function did not work as an
125 aggregate when used without 'GROUP BY'.
126 (bug #46
129 Sat Oct 19 23:37:23 2013 Pyravlos Team
131 * Version 3.2.9 released.
133 * Added support for the following google chart types: PieChart,
134 AreaChart and ColumnChart to strabon endpoint.
136 * Added Timemap as new results format in Strabon endpoint. This
137 option displays results in a map and a timeline on the same time,
138 using the Timemap js library (
139 The KMLWriter has been extended for that purpose, by transforming
140 dateTime values that are included in the result set into the respective
141 TimeStamp KML primitive (
142 In the "temporals" branch, the values of the strdf:period datatype
143 are converted into the respective KML TimeSpan primitive.
145 * Added extension function <> which is
146 mapped to the ST_Centroid(geometry) extension function of PostGIS.
147 See also: <>.
149 * Added extension function <> which is
150 mapped to the ST_MakeLine(geometry, geometry) extension function of
151 PostGIS. See also: <>.
153 * Added PostGIS vocabulary class.
155 * Added support of all SPARQL result types provided by Sesame (json,
156 xml, csv, tsv, binary). To get the respective writer, just prepend the
157 string "SPARQL/", e.g., "SPARQL/JSON". This is to ensure that we
158 support all SPARQL result formats of the SPARQL Protocol.
160 * Fixed a bug where a non-implemented extension function would make
161 Strabon throw a NULL pointer exception. Now we get away with it
162 through a warning.
164 * Strabon endpoint now publishes the URIs of the supported units of
165 measure for use in strdf:distance and geof:distance functions of
166 stSPARQL and GeoSPARQL, respectively. The URIs are those defined by
167 OGC Units of Measure 1.0 specification which may be found at
168 Strabon endpoint publishes
169 the URIs at http://localhost:8080/endpoint/Capabilities.
171 * Created new module with name 'vocab` and artifactId
172 'strabon-vocabulary` and moved there. Other
173 vocabularies have been added as well, such as Simple Features, and
174 GeoSPARQL.
176 * Strabon endpoint now publishes the URIs of the supported extension
177 functions for stSPARQL and GeoSPARQL. One should access them by
178 hitting the link http://localhost:8080/endpoint/Capabilities.
180 * Support for parsing EPSG URIs in geometry literals with datatype
181 geo:wktLiteral.
182 (bug #33:
184 * Endpoint Client now supports querying of Virtuoso and Parliament endpoints.
186 * Endpoint Client now supports store and update operations, but only
187 for Strabon Endpoints.
189 * GeoSPARQL functions sfCrosses, sfOverlaps, ehOverlaps do not use the
190 ST_Relate PostGIS function (bug #24:
192 * All Simple Features functions of GeoSPARQL do not use the ST_Relate
193 PostGIS function
195 * Added diffTime function. This function performs the difference
196 between two literals of xsd:time datatype and returns a literal of
197 the xsd:time datatype as well.
199 * Added a testsuite package in default branch. Full tester guide can be found
200 in README. Among other, most of GeoSPARQL compliance tests
201 (, pg. 53) have been
202 implemented.
204 * Changed the definition and implementation of strdf:distance function, by
205 adopting the definition of GeoSPARQL.
206 (bug #23:
208 * Changed the definition and implementation of strdf:buffer function, by
209 adopting the definition of GeoSPARQL.
210 (bug #35:
212 * Added geof:distance and geof:buffer functions, which have the same definition
213 with strdf:distance and strdf:buffer respectively.
214 (bug #32:
216 * Added a download button when performing describe and construct queries at the
217 endpoint.
218 (bug #38:
220 * Fixed a bug, where XMLWriter and TSVWriter did not return geometries with the
221 SRID.
222 (bug #47:
224 * Fixed a bug where the GeoSPARQL construct functions did not return the datatype
225 geo:wktLiteral datatype but strdf:WKT.
227 Tue Mar 26 13:28:26 2013 Pyravlos Team
229 * Version 3.2.8 released.
231 * Added support for handling (storing/querying) GeoSPARQL datatypes.
232 (bug #31:
234 * Fixed a bug in StoreOp that wouldn't close the connection, neither
235 rollback the transaction upon an exception. This had as a side effect
236 the abnormal termination of StoreOp (through for example the use of
237 Ctrl-C signal) which was leaving the database locked.
239 * Fixed bug where spatial aggregates (e.g., union) didn't work as
240 expected when the query didn't contain a `GROUP BY' clause.
241 (bug #22:
243 * Updated GeoSPARQL namespaces and fixed function names to comply with
244 the GeoSPARQL specification.
245 (bug #25:
247 Wed Jan 09 18:06:41 2013 Pyravlos Team
249 * Version 3.2.7 released.
251 * Add an extension function
252 <> for computing the
253 span (in milliseconds) between two timestamps.
255 * Added an <endpoint-exec> module. This module builds an executable jar file
256 with an embedded Apache Tomcat 7. To create and run the executable jar just
257 type:
258 $ mvn clean package
259 $ java -jar endpoint-exec/target/strabon-endpoint-executable-*.jar
261 * Modified strabon script and postgis/monetdb.StoreOP class to get an
262 option for storing a RDF file in a named graph. Moreover, the RDF
263 format of the input RDF file now is given as an option (still, if it
264 is missing, it is assumed that the input is in N-TRIPLES format). The
265 option for the format is -f and the option for the named graph is -g
266 (takes a URI as an argument).
268 * Modified the names of the stSPARQL extension functions that
269 utilize the minimum bounding boxes of the involved geometries.
271 Tue Dec 11 19:33:45 2012 Pyravlos Team
273 * Version 3.2.6 released.
275 * Modified the names of the stSPARQL extension functions to comply
276 with the OGC Simple Features Access standard.
278 Tue Dec 11 00:11:43 2012 Pyravlos Team
280 * Version 3.2.5 released.
282 * Added support for querying temporal information. This functionality
283 may be found in the `temporals' branch.
285 The datatypes <> and
286 <> are used to
287 represent periods and instants respectively.
289 The valid time time of triples is represented using quadtruples,
290 with the valid time annotation(instant or period) being the
291 fourth element of the quad. In the same way, temporal triple
292 patterns are used in queries to retrieve the valid time of
293 triples.
295 Some functions have been renamed (their URIs have changed) to
296 follow the names of the respective relations of Allen's
297 interval algebra and other functions have been added.
299 The following temporal functions are supported:
300 during, periodOverlaps, equalsPeriod, nequalsPeriod, adjacent,
301 before, after, overleft, overright, meets, starts, finishes,
302 period_intersect, period_union, preceding_period, and
303 succeeding_period.
305 * Changed behaviour of Strabon and Strabon Endpoint for connecting to
306 a spatially-enabled database. Only one instance of Strabon is allowed
307 at a time.
309 * Implemented a Java client for Strabon Endpoint. The client should be
310 used only with endpoint versions >=3.2.5. The implementation may be
311 found int the `endpoint-client' submodule of maven. Currently, only
312 querying of Strabon Endpoints is supported.
314 * Added support for requesting the capabilities of Strabon Endpoint
315 (fixes Bug #20 <>). See
316 changesets f840796400bf and ?<TBC>? for specific details and how you
317 can determine the capabilities of older endpoints (versions <= 3.2.4).
319 * Updated KML writer to include the projected variables of an stSPARQL
320 query in "ExtendedData" and "Data" tags. This is the proper way to
321 do it if we need to convert a KML to a ESRI shapefile and also include
322 such information as attributes for a feature. See related pages from
323 KML specification:
324 <>
325 <>
327 * Added user authentication for storing RDF data through Strabon
328 Endpoint. The credentials are specified in
329 WEB-INF/ file.
331 * Strabon Endpoints now limits the number of the results to a maximum
332 one. The maximum number is specified in the beans.xml file. This
333 corresponds to parameter "maxLimit". The endpoint script has also been
334 updated correspondingly; the limit can be given using the option "-l".
335 One can disable limiting of query results, by setting the "maxLimit"
336 parameter to 0. Addresses Bug #6
337 (<>).
339 * Added "Known Issues" section to README.
341 * Added -m (more memory) and -M (much more memory) options in strabon
342 script for out-of-memory exceptions.
344 * Fixed Bug #10 (<>). Now
345 KMLWriter handles more geometric types (other than polygons). See
346 changeset 9a3bfee64a39.
348 * Menu and navigation in Strabon Endpoint has changed to use jquery.
349 The menu is now populated using the queries placed inside the beans.xml.
351 * Added BrowseBean and browse.jsp for browsing the RDF data using the
352 Strabon Endpoint.
