3 * Version 3.2.10 released.
5 * Various changes in the interface and behavior of Strabon Endpoint:
6 - Revised the logos and the sample queries.
7 - Results query limit is set to zero (unlimited).
8 - Users can now store RDF data that is present in a file on the
9 client side (the file is uploaded to the server).
10 - Credentials are now required for uploading files or executing
11 UPDATE queries, unless Strabon Endpoint runs locally (localhost).
12 - When viewing the results of queries in HTML, any URI is now an
13 active link to itself. Previously, that URI was being DESCRIBEd
14 and one was being transferred to a page viewing the result of the
15 DESCRIBE query.
16 - The DESCRIBE functionality can now be accessed through the menu bar.
18 * Fixed a bug where strdf:intersection function did not work as an
19 aggregate when used without 'GROUP BY'.

22 Sat Oct 19 23:37:23 2013 Pyravlos Team
24 * Version 3.2.9 released.
26 * Added support for the following google chart types: PieChart,
27 AreaChart and ColumnChart to strabon endpoint.
29 * Added Timemap as new results format in Strabon endpoint. This
30 option displays results in a map and a timeline on the same time,
31 using the Timemap js library (
32 The KMLWriter has been extended for that purpose, by transforming
33 dateTime values that are included in the result set into the respective
34 TimeStamp KML primitive (
35 In the "temporals" branch, the values of the strdf:period datatype
36 are converted into the respective KML TimeSpan primitive.
38 * Added extension function <> which is
39 mapped to the ST_Centroid(geometry) extension function of PostGIS.
40 See also: <>.
42 * Added extension function <> which is
43 mapped to the ST_MakeLine(geometry, geometry) extension function of
44 PostGIS. See also: <>.
46 * Added PostGIS vocabulary class.
48 * Added support of all SPARQL result types provided by Sesame (json,
49 xml, csv, tsv, binary). To get the respective writer, just prepend the
50 string "SPARQL/", e.g., "SPARQL/JSON". This is to ensure that we
51 support all SPARQL result formats of the SPARQL Protocol.
53 * Fixed a bug where a non-implemented extension function would make
54 Strabon throw a NULL pointer exception. Now we get away with it
55 through a warning.
57 * Strabon endpoint now publishes the URIs of the supported units of
58 measure for use in strdf:distance and geof:distance functions of
59 stSPARQL and GeoSPARQL, respectively. The URIs are those defined by
60 OGC Units of Measure 1.0 specification which may be found at
61 Strabon endpoint publishes
62 the URIs at http://localhost:8080/endpoint/Capabilities.
64 * Created new module with name 'vocab` and artifactId
65 'strabon-vocabulary` and moved there. Other
66 vocabularies have been added as well, such as Simple Features, and
69 * Strabon endpoint now publishes the URIs of the supported extension
70 functions for stSPARQL and GeoSPARQL. One should access them by
71 hitting the link http://localhost:8080/endpoint/Capabilities.
73 * Support for parsing EPSG URIs in geometry literals with datatype
74 geo:wktLiteral.
75 (bug #33:
77 * Endpoint Client now supports querying of Virtuoso and Parliament endpoints.
79 * Endpoint Client now supports store and update operations, but only
80 for Strabon Endpoints.
82 * GeoSPARQL functions sfCrosses, sfOverlaps, ehOverlaps do not use the
83 ST_Relate PostGIS function (bug #24:
85 * All Simple Features functions of GeoSPARQL do not use the ST_Relate
86 PostGIS function
88 * Added diffTime function. This function performs the difference
89 between two literals of xsd:time datatype and returns a literal of
90 the xsd:time datatype as well.
92 * Added a testsuite package in default branch. Full tester guide can be found
93 in README. Among other, most of GeoSPARQL compliance tests
94 (, pg. 53) have been
95 implemented.
97 * Changed the definition and implementation of strdf:distance function, by
98 adopting the definition of GeoSPARQL.
99 (bug #23:
101 * Changed the definition and implementation of strdf:buffer function, by
102 adopting the definition of GeoSPARQL.
103 (bug #35:
105 * Added geof:distance and geof:buffer functions, which have the same definition
106 with strdf:distance and strdf:buffer respectively.
107 (bug #32:
109 * Added a download button when performing describe and construct queries at the
110 endpoint.
111 (bug #38:
113 * Fixed a bug, where XMLWriter and TSVWriter did not return geometries with the
114 SRID.
115 (bug #47:
117 * Fixed a bug where the GeoSPARQL construct functions did not return the datatype
118 geo:wktLiteral datatype but strdf:WKT.
120 Tue Mar 26 13:28:26 2013 Pyravlos Team
122 * Version 3.2.8 released.
124 * Added support for handling (storing/querying) GeoSPARQL datatypes.
125 (bug #31:
127 * Fixed a bug in StoreOp that wouldn't close the connection, neither
128 rollback the transaction upon an exception. This had as a side effect
129 the abnormal termination of StoreOp (through for example the use of
130 Ctrl-C signal) which was leaving the database locked.
132 * Fixed bug where spatial aggregates (e.g., union) didn't work as
133 expected when the query didn't contain a `GROUP BY' clause.
134 (bug #22:
136 * Updated GeoSPARQL namespaces and fixed function names to comply with
137 the GeoSPARQL specification.
138 (bug #25:
140 Wed Jan 09 18:06:41 2013 Pyravlos Team
142 * Version 3.2.7 released.
144 * Add an extension function
145 <> for computing the
146 span (in milliseconds) between two timestamps.
148 * Added an <endpoint-exec> module. This module builds an executable jar file
149 with an embedded Apache Tomcat 7. To create and run the executable jar just
150 type:
151 $ mvn clean package
152 $ java -jar endpoint-exec/target/strabon-endpoint-executable-*.jar
154 * Modified strabon script and postgis/monetdb.StoreOP class to get an
155 option for storing a RDF file in a named graph. Moreover, the RDF
156 format of the input RDF file now is given as an option (still, if it
157 is missing, it is assumed that the input is in N-TRIPLES format). The
158 option for the format is -f and the option for the named graph is -g
159 (takes a URI as an argument).
161 * Modified the names of the stSPARQL extension functions that
162 utilize the minimum bounding boxes of the involved geometries.
164 Tue Dec 11 19:33:45 2012 Pyravlos Team
166 * Version 3.2.6 released.
168 * Modified the names of the stSPARQL extension functions to comply
169 with the OGC Simple Features Access standard.
171 Tue Dec 11 00:11:43 2012 Pyravlos Team
173 * Version 3.2.5 released.
175 * Added support for querying temporal information. This functionality
176 may be found in the `temporals' branch.
178 The datatypes <> and
179 <> are used to
180 represent periods and instants respectively.
182 The valid time time of triples is represented using quadtruples,
183 with the valid time annotation(instant or period) being the
184 fourth element of the quad. In the same way, temporal triple
185 patterns are used in queries to retrieve the valid time of
186 triples.
188 Some functions have been renamed (their URIs have changed) to
189 follow the names of the respective relations of Allen's
190 interval algebra and other functions have been added.
192 The following temporal functions are supported:
193 during, periodOverlaps, equalsPeriod, nequalsPeriod, adjacent,
194 before, after, overleft, overright, meets, starts, finishes,
195 period_intersect, period_union, preceding_period, and
196 succeeding_period.
198 * Changed behaviour of Strabon and Strabon Endpoint for connecting to
199 a spatially-enabled database. Only one instance of Strabon is allowed
200 at a time.
202 * Implemented a Java client for Strabon Endpoint. The client should be
203 used only with endpoint versions >=3.2.5. The implementation may be
204 found int the `endpoint-client' submodule of maven. Currently, only
205 querying of Strabon Endpoints is supported.
207 * Added support for requesting the capabilities of Strabon Endpoint
208 (fixes Bug #20 <>). See
209 changesets f840796400bf and ?<TBC>? for specific details and how you
210 can determine the capabilities of older endpoints (versions <= 3.2.4).
212 * Updated KML writer to include the projected variables of an stSPARQL
213 query in "ExtendedData" and "Data" tags. This is the proper way to
214 do it if we need to convert a KML to a ESRI shapefile and also include
215 such information as attributes for a feature. See related pages from
216 KML specification:
217 <>
218 <>
220 * Added user authentication for storing RDF data through Strabon
221 Endpoint. The credentials are specified in
222 WEB-INF/ file.
224 * Strabon Endpoints now limits the number of the results to a maximum
225 one. The maximum number is specified in the beans.xml file. This
226 corresponds to parameter "maxLimit". The endpoint script has also been
227 updated correspondingly; the limit can be given using the option "-l".
228 One can disable limiting of query results, by setting the "maxLimit"
229 parameter to 0. Addresses Bug #6
230 (<>).
232 * Added "Known Issues" section to README.
234 * Added -m (more memory) and -M (much more memory) options in strabon
235 script for out-of-memory exceptions.
237 * Fixed Bug #10 (<>). Now
238 KMLWriter handles more geometric types (other than polygons). See
239 changeset 9a3bfee64a39.
241 * Menu and navigation in Strabon Endpoint has changed to use jquery.
242 The menu is now populated using the queries placed inside the beans.xml.
244 * Added BrowseBean and browse.jsp for browsing the RDF data using the
245 Strabon Endpoint.
