2 * Version 3.2.10 released.
4 * The test suite of Strabon has now reached a mature level. It
5 contains tests for both stSPARQL and GeoSPARQL query languages and
6 most of the compliance tests covered in the specification of
7 GeoSPARQL (well, only those tests for the components that we have
8 chosen to implement).
10 * The endpoint now parses Accept headers with multiple values and uses
11 the first mimetype corresponding to a valid stSPARQLQueryResultFormat.
12 (bug #64:
14 * The endpoint now registers a handler for SIGTERM signals, so that if
15 it is run from the command-line (endpoint-exec), then the closing of
16 the connection will be ultimately called.
17 (bug #40:
19 * Strabon goes debian v1. the endpoint-exec jar is now given in a .deb
20 format. By dpkg-ing it, one can run a stand alone strabon endpoint
21 locally.
22 (bug #45
24 * Fixed a bug in which Strabon hanged when a unary spatial construct
25 had a ternary spatial construct as argument.
26 (bug #45
28 * Fixed a bug according to which spatial functions in ORDER BY were not
29 evaluated at all.
30 (bug #62:
32 * Fixed a bug according to which spatial boolean functions appearing
33 in the SELECT clause were raising a NULL pointer exception.
34 (bug #34:
36 * Fixed a bug in queries that contain variables that exist inside
37 spatial functions in select and do not exist in the where clause
38 made Strabon throw a NULL pointer exception.
39 (bug #51
41 * Various changes in the interface and behavior of Strabon Endpoint:
42 - Revised the logos and the sample queries.
43 - Results query limit is set to zero (unlimited).
44 - Users can now store RDF data that is present in a file on the
45 client side (the file is uploaded to the server).
46 - Credentials are now required for uploading files or executing
47 UPDATE queries, unless Strabon Endpoint runs locally (localhost).
48 - When viewing the results of queries in HTML, any URI is now an
49 active link to itself. Previously, that URI was being DESCRIBEd
50 and one was being transferred to a page viewing the result of the
51 DESCRIBE query.
52 - The DESCRIBE functionality can now be accessed through the menu bar.
54 * Fixed a bug where strdf:intersection function did not work as an
55 aggregate when used without 'GROUP BY'.
56 (bug #46
59 Sat Oct 19 23:37:23 2013 Pyravlos Team
61 * Version 3.2.9 released.
63 * Added support for the following google chart types: PieChart,
64 AreaChart and ColumnChart to strabon endpoint.
66 * Added Timemap as new results format in Strabon endpoint. This
67 option displays results in a map and a timeline on the same time,
68 using the Timemap js library (
69 The KMLWriter has been extended for that purpose, by transforming
70 dateTime values that are included in the result set into the respective
71 TimeStamp KML primitive (
72 In the "temporals" branch, the values of the strdf:period datatype
73 are converted into the respective KML TimeSpan primitive.
75 * Added extension function <> which is
76 mapped to the ST_Centroid(geometry) extension function of PostGIS.
77 See also: <>.
79 * Added extension function <> which is
80 mapped to the ST_MakeLine(geometry, geometry) extension function of
81 PostGIS. See also: <>.
83 * Added PostGIS vocabulary class.
85 * Added support of all SPARQL result types provided by Sesame (json,
86 xml, csv, tsv, binary). To get the respective writer, just prepend the
87 string "SPARQL/", e.g., "SPARQL/JSON". This is to ensure that we
88 support all SPARQL result formats of the SPARQL Protocol.
90 * Fixed a bug where a non-implemented extension function would make
91 Strabon throw a NULL pointer exception. Now we get away with it
92 through a warning.
94 * Strabon endpoint now publishes the URIs of the supported units of
95 measure for use in strdf:distance and geof:distance functions of
96 stSPARQL and GeoSPARQL, respectively. The URIs are those defined by
97 OGC Units of Measure 1.0 specification which may be found at
98 Strabon endpoint publishes
99 the URIs at http://localhost:8080/endpoint/Capabilities.
101 * Created new module with name 'vocab` and artifactId
102 'strabon-vocabulary` and moved there. Other
103 vocabularies have been added as well, such as Simple Features, and
104 GeoSPARQL.
106 * Strabon endpoint now publishes the URIs of the supported extension
107 functions for stSPARQL and GeoSPARQL. One should access them by
108 hitting the link http://localhost:8080/endpoint/Capabilities.
110 * Support for parsing EPSG URIs in geometry literals with datatype
111 geo:wktLiteral.
112 (bug #33:
114 * Endpoint Client now supports querying of Virtuoso and Parliament endpoints.
116 * Endpoint Client now supports store and update operations, but only
117 for Strabon Endpoints.
119 * GeoSPARQL functions sfCrosses, sfOverlaps, ehOverlaps do not use the
120 ST_Relate PostGIS function (bug #24:
122 * All Simple Features functions of GeoSPARQL do not use the ST_Relate
123 PostGIS function
125 * Added diffTime function. This function performs the difference
126 between two literals of xsd:time datatype and returns a literal of
127 the xsd:time datatype as well.
129 * Added a testsuite package in default branch. Full tester guide can be found
130 in README. Among other, most of GeoSPARQL compliance tests
131 (, pg. 53) have been
132 implemented.
134 * Changed the definition and implementation of strdf:distance function, by
135 adopting the definition of GeoSPARQL.
136 (bug #23:
138 * Changed the definition and implementation of strdf:buffer function, by
139 adopting the definition of GeoSPARQL.
140 (bug #35:
142 * Added geof:distance and geof:buffer functions, which have the same definition
143 with strdf:distance and strdf:buffer respectively.
144 (bug #32:
146 * Added a download button when performing describe and construct queries at the
147 endpoint.
148 (bug #38:
150 * Fixed a bug, where XMLWriter and TSVWriter did not return geometries with the
151 SRID.
152 (bug #47:
154 * Fixed a bug where the GeoSPARQL construct functions did not return the datatype
155 geo:wktLiteral datatype but strdf:WKT.
157 Tue Mar 26 13:28:26 2013 Pyravlos Team
159 * Version 3.2.8 released.
161 * Added support for handling (storing/querying) GeoSPARQL datatypes.
162 (bug #31:
164 * Fixed a bug in StoreOp that wouldn't close the connection, neither
165 rollback the transaction upon an exception. This had as a side effect
166 the abnormal termination of StoreOp (through for example the use of
167 Ctrl-C signal) which was leaving the database locked.
169 * Fixed bug where spatial aggregates (e.g., union) didn't work as
170 expected when the query didn't contain a `GROUP BY' clause.
171 (bug #22:
173 * Updated GeoSPARQL namespaces and fixed function names to comply with
174 the GeoSPARQL specification.
175 (bug #25:
177 Wed Jan 09 18:06:41 2013 Pyravlos Team
179 * Version 3.2.7 released.
181 * Add an extension function
182 <> for computing the
183 span (in milliseconds) between two timestamps.
185 * Added an <endpoint-exec> module. This module builds an executable jar file
186 with an embedded Apache Tomcat 7. To create and run the executable jar just
187 type:
188 $ mvn clean package
189 $ java -jar endpoint-exec/target/strabon-endpoint-executable-*.jar
191 * Modified strabon script and postgis/monetdb.StoreOP class to get an
192 option for storing a RDF file in a named graph. Moreover, the RDF
193 format of the input RDF file now is given as an option (still, if it
194 is missing, it is assumed that the input is in N-TRIPLES format). The
195 option for the format is -f and the option for the named graph is -g
196 (takes a URI as an argument).
198 * Modified the names of the stSPARQL extension functions that
199 utilize the minimum bounding boxes of the involved geometries.
201 Tue Dec 11 19:33:45 2012 Pyravlos Team
203 * Version 3.2.6 released.
205 * Modified the names of the stSPARQL extension functions to comply
206 with the OGC Simple Features Access standard.
208 Tue Dec 11 00:11:43 2012 Pyravlos Team
210 * Version 3.2.5 released.
212 * Added support for querying temporal information. This functionality
213 may be found in the `temporals' branch.
215 The datatypes <> and
216 <> are used to
217 represent periods and instants respectively.
219 The valid time time of triples is represented using quadtruples,
220 with the valid time annotation(instant or period) being the
221 fourth element of the quad. In the same way, temporal triple
222 patterns are used in queries to retrieve the valid time of
223 triples.
225 Some functions have been renamed (their URIs have changed) to
226 follow the names of the respective relations of Allen's
227 interval algebra and other functions have been added.
229 The following temporal functions are supported:
230 during, periodOverlaps, equalsPeriod, nequalsPeriod, adjacent,
231 before, after, overleft, overright, meets, starts, finishes,
232 period_intersect, period_union, preceding_period, and
233 succeeding_period.
235 * Changed behaviour of Strabon and Strabon Endpoint for connecting to
236 a spatially-enabled database. Only one instance of Strabon is allowed
237 at a time.
239 * Implemented a Java client for Strabon Endpoint. The client should be
240 used only with endpoint versions >=3.2.5. The implementation may be
241 found int the `endpoint-client' submodule of maven. Currently, only
242 querying of Strabon Endpoints is supported.
244 * Added support for requesting the capabilities of Strabon Endpoint
245 (fixes Bug #20 <>). See
246 changesets f840796400bf and ?<TBC>? for specific details and how you
247 can determine the capabilities of older endpoints (versions <= 3.2.4).
249 * Updated KML writer to include the projected variables of an stSPARQL
250 query in "ExtendedData" and "Data" tags. This is the proper way to
251 do it if we need to convert a KML to a ESRI shapefile and also include
252 such information as attributes for a feature. See related pages from
253 KML specification:
254 <>
255 <>
257 * Added user authentication for storing RDF data through Strabon
258 Endpoint. The credentials are specified in
259 WEB-INF/ file.
261 * Strabon Endpoints now limits the number of the results to a maximum
262 one. The maximum number is specified in the beans.xml file. This
263 corresponds to parameter "maxLimit". The endpoint script has also been
264 updated correspondingly; the limit can be given using the option "-l".
265 One can disable limiting of query results, by setting the "maxLimit"
266 parameter to 0. Addresses Bug #6
267 (<>).
269 * Added "Known Issues" section to README.
271 * Added -m (more memory) and -M (much more memory) options in strabon
272 script for out-of-memory exceptions.
274 * Fixed Bug #10 (<>). Now
275 KMLWriter handles more geometric types (other than polygons). See
276 changeset 9a3bfee64a39.
278 * Menu and navigation in Strabon Endpoint has changed to use jquery.
279 The menu is now populated using the queries placed inside the beans.xml.
281 * Added BrowseBean and browse.jsp for browsing the RDF data using the
282 Strabon Endpoint.
