3 * Version 3.2.10 released.
5 * The test suite of Strabon has now reached a mature level. It
6 contains tests for both stSPARQL and GeoSPARQL query languages and
7 most of the compliance tests covered in the specification of
8 GeoSPARQL (well, only those tests for the components that we have
9 chosen to implement).
11 * The endpoint now parses Accept headers with multiple values and uses
12 the first mimetype corresponding to a valid stSPARQLQueryResultFormat.
13 (bug #64:
15 * The endpoint now registers a handler for SIGTERM signals, so that if
16 it is run from the command-line (endpoint-exec), then the closing of
17 the connection will be ultimately called.
18 (bug #40:
20 * Strabon goes debian v1. the endpoint-exec jar is now given in a .deb
21 format. By dpkg-ing it, one can run a stand alone strabon endpoint
22 locally.
23 (bug #45
25 * Fixed a bug in which Strabon hanged when a unary spatial construct
26 had a ternary spatial construct as argument.
27 (bug #45
29 * Fixed a bug according to which spatial functions in ORDER BY were not
30 evaluated at all.
31 (bug #62:
33 * Fixed a bug according to which spatial boolean functions appearing
34 in the SELECT clause were raising a NULL pointer exception.
35 (bug #34:
37 * Fixed a bug in queries that contain variables that exist inside
38 spatial functions in select and do not exist in the where clause
39 made Strabon throw a NULL pointer exception.
40 (bug #51
42 * Various changes in the interface and behavior of Strabon Endpoint:
43 - Revised the logos and the sample queries.
44 - Results query limit is set to zero (unlimited).
45 - Users can now store RDF data that is present in a file on the
46 client side (the file is uploaded to the server).
47 - Credentials are now required for uploading files or executing
48 UPDATE queries, unless Strabon Endpoint runs locally (localhost).
49 - When viewing the results of queries in HTML, any URI is now an
50 active link to itself. Previously, that URI was being DESCRIBEd
51 and one was being transferred to a page viewing the result of the
52 DESCRIBE query.
53 - The DESCRIBE functionality can now be accessed through the menu bar.
55 * Fixed a bug where strdf:intersection function did not work as an
56 aggregate when used without 'GROUP BY'.
57 (bug #46
60 Sat Oct 19 23:37:23 2013 Pyravlos Team
62 * Version 3.2.9 released.
64 * Added support for the following google chart types: PieChart,
65 AreaChart and ColumnChart to strabon endpoint.
67 * Added Timemap as new results format in Strabon endpoint. This
68 option displays results in a map and a timeline on the same time,
69 using the Timemap js library (
70 The KMLWriter has been extended for that purpose, by transforming
71 dateTime values that are included in the result set into the respective
72 TimeStamp KML primitive (
73 In the "temporals" branch, the values of the strdf:period datatype
74 are converted into the respective KML TimeSpan primitive.
76 * Added extension function <> which is
77 mapped to the ST_Centroid(geometry) extension function of PostGIS.
78 See also: <>.
80 * Added extension function <> which is
81 mapped to the ST_MakeLine(geometry, geometry) extension function of
82 PostGIS. See also: <>.
84 * Added PostGIS vocabulary class.
86 * Added support of all SPARQL result types provided by Sesame (json,
87 xml, csv, tsv, binary). To get the respective writer, just prepend the
88 string "SPARQL/", e.g., "SPARQL/JSON". This is to ensure that we
89 support all SPARQL result formats of the SPARQL Protocol.
91 * Fixed a bug where a non-implemented extension function would make
92 Strabon throw a NULL pointer exception. Now we get away with it
93 through a warning.
95 * Strabon endpoint now publishes the URIs of the supported units of
96 measure for use in strdf:distance and geof:distance functions of
97 stSPARQL and GeoSPARQL, respectively. The URIs are those defined by
98 OGC Units of Measure 1.0 specification which may be found at
99 Strabon endpoint publishes
100 the URIs at http://localhost:8080/endpoint/Capabilities.
102 * Created new module with name 'vocab` and artifactId
103 'strabon-vocabulary` and moved there. Other
104 vocabularies have been added as well, such as Simple Features, and
105 GeoSPARQL.
107 * Strabon endpoint now publishes the URIs of the supported extension
108 functions for stSPARQL and GeoSPARQL. One should access them by
109 hitting the link http://localhost:8080/endpoint/Capabilities.
111 * Support for parsing EPSG URIs in geometry literals with datatype
112 geo:wktLiteral.
113 (bug #33:
115 * Endpoint Client now supports querying of Virtuoso and Parliament endpoints.
117 * Endpoint Client now supports store and update operations, but only
118 for Strabon Endpoints.
120 * GeoSPARQL functions sfCrosses, sfOverlaps, ehOverlaps do not use the
121 ST_Relate PostGIS function (bug #24:
123 * All Simple Features functions of GeoSPARQL do not use the ST_Relate
124 PostGIS function
126 * Added diffTime function. This function performs the difference
127 between two literals of xsd:time datatype and returns a literal of
128 the xsd:time datatype as well.
130 * Added a testsuite package in default branch. Full tester guide can be found
131 in README. Among other, most of GeoSPARQL compliance tests
132 (, pg. 53) have been
133 implemented.
135 * Changed the definition and implementation of strdf:distance function, by
136 adopting the definition of GeoSPARQL.
137 (bug #23:
139 * Changed the definition and implementation of strdf:buffer function, by
140 adopting the definition of GeoSPARQL.
141 (bug #35:
143 * Added geof:distance and geof:buffer functions, which have the same definition
144 with strdf:distance and strdf:buffer respectively.
145 (bug #32:
147 * Added a download button when performing describe and construct queries at the
148 endpoint.
149 (bug #38:
151 * Fixed a bug, where XMLWriter and TSVWriter did not return geometries with the
152 SRID.
153 (bug #47:
155 * Fixed a bug where the GeoSPARQL construct functions did not return the datatype
156 geo:wktLiteral datatype but strdf:WKT.
158 Tue Mar 26 13:28:26 2013 Pyravlos Team
160 * Version 3.2.8 released.
162 * Added support for handling (storing/querying) GeoSPARQL datatypes.
163 (bug #31:
165 * Fixed a bug in StoreOp that wouldn't close the connection, neither
166 rollback the transaction upon an exception. This had as a side effect
167 the abnormal termination of StoreOp (through for example the use of
168 Ctrl-C signal) which was leaving the database locked.
170 * Fixed bug where spatial aggregates (e.g., union) didn't work as
171 expected when the query didn't contain a `GROUP BY' clause.
172 (bug #22:
174 * Updated GeoSPARQL namespaces and fixed function names to comply with
175 the GeoSPARQL specification.
176 (bug #25:
178 Wed Jan 09 18:06:41 2013 Pyravlos Team
180 * Version 3.2.7 released.
182 * Add an extension function
183 <> for computing the
184 span (in milliseconds) between two timestamps.
186 * Added an <endpoint-exec> module. This module builds an executable jar file
187 with an embedded Apache Tomcat 7. To create and run the executable jar just
188 type:
189 $ mvn clean package
190 $ java -jar endpoint-exec/target/strabon-endpoint-executable-*.jar
192 * Modified strabon script and postgis/monetdb.StoreOP class to get an
193 option for storing a RDF file in a named graph. Moreover, the RDF
194 format of the input RDF file now is given as an option (still, if it
195 is missing, it is assumed that the input is in N-TRIPLES format). The
196 option for the format is -f and the option for the named graph is -g
197 (takes a URI as an argument).
199 * Modified the names of the stSPARQL extension functions that
200 utilize the minimum bounding boxes of the involved geometries.
202 Tue Dec 11 19:33:45 2012 Pyravlos Team
204 * Version 3.2.6 released.
206 * Modified the names of the stSPARQL extension functions to comply
207 with the OGC Simple Features Access standard.
209 Tue Dec 11 00:11:43 2012 Pyravlos Team
211 * Version 3.2.5 released.
213 * Added support for querying temporal information. This functionality
214 may be found in the `temporals' branch.
216 The datatypes <> and
217 <> are used to
218 represent periods and instants respectively.
220 The valid time time of triples is represented using quadtruples,
221 with the valid time annotation(instant or period) being the
222 fourth element of the quad. In the same way, temporal triple
223 patterns are used in queries to retrieve the valid time of
224 triples.
226 Some functions have been renamed (their URIs have changed) to
227 follow the names of the respective relations of Allen's
228 interval algebra and other functions have been added.
230 The following temporal functions are supported:
231 during, periodOverlaps, equalsPeriod, nequalsPeriod, adjacent,
232 before, after, overleft, overright, meets, starts, finishes,
233 period_intersect, period_union, preceding_period, and
234 succeeding_period.
236 * Changed behaviour of Strabon and Strabon Endpoint for connecting to
237 a spatially-enabled database. Only one instance of Strabon is allowed
238 at a time.
240 * Implemented a Java client for Strabon Endpoint. The client should be
241 used only with endpoint versions >=3.2.5. The implementation may be
242 found int the `endpoint-client' submodule of maven. Currently, only
243 querying of Strabon Endpoints is supported.
245 * Added support for requesting the capabilities of Strabon Endpoint
246 (fixes Bug #20 <>). See
247 changesets f840796400bf and ?<TBC>? for specific details and how you
248 can determine the capabilities of older endpoints (versions <= 3.2.4).
250 * Updated KML writer to include the projected variables of an stSPARQL
251 query in "ExtendedData" and "Data" tags. This is the proper way to
252 do it if we need to convert a KML to a ESRI shapefile and also include
253 such information as attributes for a feature. See related pages from
254 KML specification:
255 <>
256 <>
258 * Added user authentication for storing RDF data through Strabon
259 Endpoint. The credentials are specified in
260 WEB-INF/ file.
262 * Strabon Endpoints now limits the number of the results to a maximum
263 one. The maximum number is specified in the beans.xml file. This
264 corresponds to parameter "maxLimit". The endpoint script has also been
265 updated correspondingly; the limit can be given using the option "-l".
266 One can disable limiting of query results, by setting the "maxLimit"
267 parameter to 0. Addresses Bug #6
268 (<>).
270 * Added "Known Issues" section to README.
272 * Added -m (more memory) and -M (much more memory) options in strabon
273 script for out-of-memory exceptions.
275 * Fixed Bug #10 (<>). Now
276 KMLWriter handles more geometric types (other than polygons). See
277 changeset 9a3bfee64a39.
279 * Menu and navigation in Strabon Endpoint has changed to use jquery.
280 The menu is now populated using the queries placed inside the beans.xml.
282 * Added BrowseBean and browse.jsp for browsing the RDF data using the
283 Strabon Endpoint.
