3 * Version 3.2.10 released.
5 * Altered default SRID to GeoSPARQL SRID: Geometries with wktLiteral
6 datatype in SPARQL queries were not interpreted in the correct CRS.
7 (bug #44
9 * Fixed a bug in queries that contain variables that exist inside
10 spatial functions in select and do not exist in the where clause
11 made Strabon throw a NULL pointer exception.
12 (bug #51
14 * Various changes in the interface and behavior of Strabon Endpoint:
15 - Revised the logos and the sample queries.
16 - Results query limit is set to zero (unlimited).
17 - Users can now store RDF data that is present in a file on the
18 client side (the file is uploaded to the server).
19 - Credentials are now required for uploading files or executing
20 UPDATE queries, unless Strabon Endpoint runs locally (localhost).
21 - When viewing the results of queries in HTML, any URI is now an
22 active link to itself. Previously, that URI was being DESCRIBEd
23 and one was being transferred to a page viewing the result of the
24 DESCRIBE query.
25 - The DESCRIBE functionality can now be accessed through the menu bar.
27 * Fixed a bug where strdf:intersection function did not work as an
28 aggregate when used without 'GROUP BY'.
29 (bug #46
32 Sat Oct 19 23:37:23 2013 Pyravlos Team
34 * Version 3.2.9 released.
36 * Added support for the following google chart types: PieChart,
37 AreaChart and ColumnChart to strabon endpoint.
39 * Added Timemap as new results format in Strabon endpoint. This
40 option displays results in a map and a timeline on the same time,
41 using the Timemap js library (
42 The KMLWriter has been extended for that purpose, by transforming
43 dateTime values that are included in the result set into the respective
44 TimeStamp KML primitive (
45 In the "temporals" branch, the values of the strdf:period datatype
46 are converted into the respective KML TimeSpan primitive.
48 * Added extension function <> which is
49 mapped to the ST_Centroid(geometry) extension function of PostGIS.
50 See also: <>.
52 * Added extension function <> which is
53 mapped to the ST_MakeLine(geometry, geometry) extension function of
54 PostGIS. See also: <>.
56 * Added PostGIS vocabulary class.
58 * Added support of all SPARQL result types provided by Sesame (json,
59 xml, csv, tsv, binary). To get the respective writer, just prepend the
60 string "SPARQL/", e.g., "SPARQL/JSON". This is to ensure that we
61 support all SPARQL result formats of the SPARQL Protocol.
63 * Fixed a bug where a non-implemented extension function would make
64 Strabon throw a NULL pointer exception. Now we get away with it
65 through a warning.
67 * Strabon endpoint now publishes the URIs of the supported units of
68 measure for use in strdf:distance and geof:distance functions of
69 stSPARQL and GeoSPARQL, respectively. The URIs are those defined by
70 OGC Units of Measure 1.0 specification which may be found at
71 Strabon endpoint publishes
72 the URIs at http://localhost:8080/endpoint/Capabilities.
74 * Created new module with name 'vocab` and artifactId
75 'strabon-vocabulary` and moved there. Other
76 vocabularies have been added as well, such as Simple Features, and
79 * Strabon endpoint now publishes the URIs of the supported extension
80 functions for stSPARQL and GeoSPARQL. One should access them by
81 hitting the link http://localhost:8080/endpoint/Capabilities.
83 * Support for parsing EPSG URIs in geometry literals with datatype
84 geo:wktLiteral.
85 (bug #33:
87 * Endpoint Client now supports querying of Virtuoso and Parliament endpoints.
89 * Endpoint Client now supports store and update operations, but only
90 for Strabon Endpoints.
92 * GeoSPARQL functions sfCrosses, sfOverlaps, ehOverlaps do not use the
93 ST_Relate PostGIS function (bug #24:
95 * All Simple Features functions of GeoSPARQL do not use the ST_Relate
96 PostGIS function
98 * Added diffTime function. This function performs the difference
99 between two literals of xsd:time datatype and returns a literal of
100 the xsd:time datatype as well.
102 * Added a testsuite package in default branch. Full tester guide can be found
103 in README. Among other, most of GeoSPARQL compliance tests
104 (, pg. 53) have been
105 implemented.
107 * Changed the definition and implementation of strdf:distance function, by
108 adopting the definition of GeoSPARQL.
109 (bug #23:
111 * Changed the definition and implementation of strdf:buffer function, by
112 adopting the definition of GeoSPARQL.
113 (bug #35:
115 * Added geof:distance and geof:buffer functions, which have the same definition
116 with strdf:distance and strdf:buffer respectively.
117 (bug #32:
119 * Added a download button when performing describe and construct queries at the
120 endpoint.
121 (bug #38:
123 * Fixed a bug, where XMLWriter and TSVWriter did not return geometries with the
124 SRID.
125 (bug #47:
127 * Fixed a bug where the GeoSPARQL construct functions did not return the datatype
128 geo:wktLiteral datatype but strdf:WKT.
130 Tue Mar 26 13:28:26 2013 Pyravlos Team
132 * Version 3.2.8 released.
134 * Added support for handling (storing/querying) GeoSPARQL datatypes.
135 (bug #31:
137 * Fixed a bug in StoreOp that wouldn't close the connection, neither
138 rollback the transaction upon an exception. This had as a side effect
139 the abnormal termination of StoreOp (through for example the use of
140 Ctrl-C signal) which was leaving the database locked.
142 * Fixed bug where spatial aggregates (e.g., union) didn't work as
143 expected when the query didn't contain a `GROUP BY' clause.
144 (bug #22:
146 * Updated GeoSPARQL namespaces and fixed function names to comply with
147 the GeoSPARQL specification.
148 (bug #25:
150 Wed Jan 09 18:06:41 2013 Pyravlos Team
152 * Version 3.2.7 released.
154 * Add an extension function
155 <> for computing the
156 span (in milliseconds) between two timestamps.
158 * Added an <endpoint-exec> module. This module builds an executable jar file
159 with an embedded Apache Tomcat 7. To create and run the executable jar just
160 type:
161 $ mvn clean package
162 $ java -jar endpoint-exec/target/strabon-endpoint-executable-*.jar
164 * Modified strabon script and postgis/monetdb.StoreOP class to get an
165 option for storing a RDF file in a named graph. Moreover, the RDF
166 format of the input RDF file now is given as an option (still, if it
167 is missing, it is assumed that the input is in N-TRIPLES format). The
168 option for the format is -f and the option for the named graph is -g
169 (takes a URI as an argument).
171 * Modified the names of the stSPARQL extension functions that
172 utilize the minimum bounding boxes of the involved geometries.
174 Tue Dec 11 19:33:45 2012 Pyravlos Team
176 * Version 3.2.6 released.
178 * Modified the names of the stSPARQL extension functions to comply
179 with the OGC Simple Features Access standard.
181 Tue Dec 11 00:11:43 2012 Pyravlos Team
183 * Version 3.2.5 released.
185 * Added support for querying temporal information. This functionality
186 may be found in the `temporals' branch.
188 The datatypes <> and
189 <> are used to
190 represent periods and instants respectively.
192 The valid time time of triples is represented using quadtruples,
193 with the valid time annotation(instant or period) being the
194 fourth element of the quad. In the same way, temporal triple
195 patterns are used in queries to retrieve the valid time of
196 triples.
198 Some functions have been renamed (their URIs have changed) to
199 follow the names of the respective relations of Allen's
200 interval algebra and other functions have been added.
202 The following temporal functions are supported:
203 during, periodOverlaps, equalsPeriod, nequalsPeriod, adjacent,
204 before, after, overleft, overright, meets, starts, finishes,
205 period_intersect, period_union, preceding_period, and
206 succeeding_period.
208 * Changed behaviour of Strabon and Strabon Endpoint for connecting to
209 a spatially-enabled database. Only one instance of Strabon is allowed
210 at a time.
212 * Implemented a Java client for Strabon Endpoint. The client should be
213 used only with endpoint versions >=3.2.5. The implementation may be
214 found int the `endpoint-client' submodule of maven. Currently, only
215 querying of Strabon Endpoints is supported.
217 * Added support for requesting the capabilities of Strabon Endpoint
218 (fixes Bug #20 <>). See
219 changesets f840796400bf and ?<TBC>? for specific details and how you
220 can determine the capabilities of older endpoints (versions <= 3.2.4).
222 * Updated KML writer to include the projected variables of an stSPARQL
223 query in "ExtendedData" and "Data" tags. This is the proper way to
224 do it if we need to convert a KML to a ESRI shapefile and also include
225 such information as attributes for a feature. See related pages from
226 KML specification:
227 <>
228 <>
230 * Added user authentication for storing RDF data through Strabon
231 Endpoint. The credentials are specified in
232 WEB-INF/ file.
234 * Strabon Endpoints now limits the number of the results to a maximum
235 one. The maximum number is specified in the beans.xml file. This
236 corresponds to parameter "maxLimit". The endpoint script has also been
237 updated correspondingly; the limit can be given using the option "-l".
238 One can disable limiting of query results, by setting the "maxLimit"
239 parameter to 0. Addresses Bug #6
240 (<>).
242 * Added "Known Issues" section to README.
244 * Added -m (more memory) and -M (much more memory) options in strabon
245 script for out-of-memory exceptions.
247 * Fixed Bug #10 (<>). Now
248 KMLWriter handles more geometric types (other than polygons). See
249 changeset 9a3bfee64a39.
251 * Menu and navigation in Strabon Endpoint has changed to use jquery.
252 The menu is now populated using the queries placed inside the beans.xml.
254 * Added BrowseBean and browse.jsp for browsing the RDF data using the
255 Strabon Endpoint.
