properly construct stRDF WKT literals (CRS URI should not be placed into <> characters); greek characters in the endpoint-client where not encoded appropriately when run from the console (Unit Testin); endpoint-client was encoding the query based on the return value of "Charset.defaultCharset()". We change excplicitly to UTF-8

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