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