corrected package names (in strabon-cmd and runtime component). Capital
letters are not allowed in debian packaging and also the two
components must have different names since they are two different
packages. Finally, the debian repo has been updated with the latest

3 * Updated package names (since repositories cannot include capital
4 letters + runtime and endpoint-exec must have different names
6 * Version 3.3.1 released.
8 * Bug #58, added script that is invoked my maven to also update the
9 version described in the deb/control file of the runtime and
10 endpoint-exec components.
12 * Related to bug #58, but it generally enhances Strabon; The runtime
13 component has also been debianized. Dependencies are added to
14 /usr/share/jdeb/lib/strabon-runtime. ClassPath and strabon script
15 have also been updated accordingly (strabon-cmd)
17 * Bug #58: Maven creates the debian package conditionally. Use
18 -Ddebian=true in the mvn package command.
20 * Bug #58: Added dependencies - java, postgresql, tomcat. Also, added
21 a strabon-init script that detects the postgis installation path
22 and sets up the template_postgis. Finally the script creates a db
23 called "endpoint" (assuming it does not already exist) that is used
24 for the strabon-endpoint command.
26 * Fixed an issue that returned null SRID when unmarshalling GML geometries if
27 the SRID did not follow one of the supported formats by GML-JTS. To fix that
28 we added a function that handles these cases by reading the userData variable
29 that JTS provides.
31 * Fixed a bug that would return no results when a variable that results
32 from a BIND clause appears in the FILTER or in the projection of a
33 query and is inside a spatial function.
34 (bug #78:
36 * Fixed the precision of the geometry literals in GeoJSON writer. Now,
37 this defaults to the precision model of JTS (equals to 16). Prior to
38 this it was fixed to 4.
40 * Now the GeoJSON writer is aware of the kind of typed literals (e.g.,
41 numeric, boolean, calendar, etc.) and prints the corresponding
42 values according to these types.
44 * Fixed a bug that would not return the correct result or would fail
45 when a spatial function involved a constant and a variable.
46 (bug #74:
48 * Fixed a bug that would not return the correct spatial datatype of a
49 projected geometry literal stored in the database.
50 (bug #71:
52 * Now, geometries expressed in CRS84 and a `geo:wktLiteral' datatype
53 are assigned the correct CRS, i.e., EPSG:4326 with a longitude
54 latitude axis order.
56 * Now, we report a parse error when a constant geometry given in a
57 SELECT or HAVING clause is not well-formed according to the WKT
58 specification.
59 (bug #69:
61 * Function `geof:convexHull' is now supported in a Having clause.
63 * Fixed older implementation of `strdf:distance' that would expect two
64 arguments instead of three when present in a HAVING clause.
66 * Fixed a bug that would cause a class cast exception for grounded
67 expressions with function nesting in the SELECT or HAVING clause.
69 * Fixed a bug in which `postgis:ST_Centroid' did not work in the SELECT
70 clause with input geometries from the database.
72 * Fixed a bug that `geof:getSRID' would return an integer instead of a
73 the URI corrresponding to the CRS that the input geometry was
74 expressed.
75 (bug #32:
77 * Fixed a bug that would raise an exception for queries involving two
78 UNION graph patterns and a projection to a predicate or a URI in
79 general.
80 (bug #53:
82 Wed Sep 17 20:14:12 2014 Pyravlos Team
84 * Version 3.2.10 released.
86 * The test suite of Strabon has now reached a mature level. It
87 contains tests for both stSPARQL and GeoSPARQL query languages and
88 most of the compliance tests covered in the specification of
89 GeoSPARQL (well, only those tests for the components that we have
90 chosen to implement).
92 * The endpoint now parses Accept headers with multiple values and uses
93 the first mimetype corresponding to a valid stSPARQLQueryResultFormat.
94 (bug #64:
96 * The endpoint now registers a handler for SIGTERM signals, so that if
97 it is run from the command-line (endpoint-exec), then the closing of
98 the connection will be ultimately called.
99 (bug #40:
101 * Strabon goes debian v1. the endpoint-exec jar is now given in a .deb
102 format. By dpkg-ing it, one can run a stand alone strabon endpoint
103 locally.
104 (bug #45
106 * Fixed a bug in which Strabon hanged when a unary spatial construct
107 had a ternary spatial construct as argument.
108 (bug #45
110 * Fixed a bug according to which spatial functions in ORDER BY were not
111 evaluated at all.
112 (bug #62:
114 * Fixed a bug according to which spatial boolean functions appearing
115 in the SELECT clause were raising a NULL pointer exception.
116 (bug #34:
118 * Fixed a bug in queries that contain variables that exist inside
119 spatial functions in select and do not exist in the where clause
120 made Strabon throw a NULL pointer exception.
121 (bug #51
123 * Various changes in the interface and behavior of Strabon Endpoint:
124 - Revised the logos and the sample queries.
125 - Results query limit is set to zero (unlimited).
126 - Users can now store RDF data that is present in a file on the
127 client side (the file is uploaded to the server).
128 - Credentials are now required for uploading files or executing
129 UPDATE queries, unless Strabon Endpoint runs locally (localhost).
130 - When viewing the results of queries in HTML, any URI is now an
131 active link to itself. Previously, that URI was being DESCRIBEd
132 and one was being transferred to a page viewing the result of the
133 DESCRIBE query.
134 - The DESCRIBE functionality can now be accessed through the menu bar.
136 * Fixed a bug where strdf:intersection function did not work as an
137 aggregate when used without 'GROUP BY'.
138 (bug #46
141 Sat Oct 19 23:37:23 2013 Pyravlos Team
143 * Version 3.2.9 released.
145 * Added support for the following google chart types: PieChart,
146 AreaChart and ColumnChart to strabon endpoint.
148 * Added Timemap as new results format in Strabon endpoint. This
149 option displays results in a map and a timeline on the same time,
150 using the Timemap js library (
151 The KMLWriter has been extended for that purpose, by transforming
152 dateTime values that are included in the result set into the respective
153 TimeStamp KML primitive (
154 In the "temporals" branch, the values of the strdf:period datatype
155 are converted into the respective KML TimeSpan primitive.
157 * Added extension function <> which is
158 mapped to the ST_Centroid(geometry) extension function of PostGIS.
159 See also: <>.
161 * Added extension function <> which is
162 mapped to the ST_MakeLine(geometry, geometry) extension function of
163 PostGIS. See also: <>.
165 * Added PostGIS vocabulary class.
167 * Added support of all SPARQL result types provided by Sesame (json,
168 xml, csv, tsv, binary). To get the respective writer, just prepend the
169 string "SPARQL/", e.g., "SPARQL/JSON". This is to ensure that we
170 support all SPARQL result formats of the SPARQL Protocol.
172 * Fixed a bug where a non-implemented extension function would make
173 Strabon throw a NULL pointer exception. Now we get away with it
174 through a warning.
176 * Strabon endpoint now publishes the URIs of the supported units of
177 measure for use in strdf:distance and geof:distance functions of
178 stSPARQL and GeoSPARQL, respectively. The URIs are those defined by
179 OGC Units of Measure 1.0 specification which may be found at
180 Strabon endpoint publishes
181 the URIs at http://localhost:8080/endpoint/Capabilities.
183 * Created new module with name 'vocab` and artifactId
184 'strabon-vocabulary` and moved there. Other
185 vocabularies have been added as well, such as Simple Features, and
186 GeoSPARQL.
188 * Strabon endpoint now publishes the URIs of the supported extension
189 functions for stSPARQL and GeoSPARQL. One should access them by
190 hitting the link http://localhost:8080/endpoint/Capabilities.
192 * Support for parsing EPSG URIs in geometry literals with datatype
193 geo:wktLiteral.
194 (bug #33:
196 * Endpoint Client now supports querying of Virtuoso and Parliament endpoints.
198 * Endpoint Client now supports store and update operations, but only
199 for Strabon Endpoints.
201 * GeoSPARQL functions sfCrosses, sfOverlaps, ehOverlaps do not use the
202 ST_Relate PostGIS function (bug #24:
204 * All Simple Features functions of GeoSPARQL do not use the ST_Relate
205 PostGIS function
207 * Added diffTime function. This function performs the difference
208 between two literals of xsd:time datatype and returns a literal of
209 the xsd:time datatype as well.
211 * Added a testsuite package in default branch. Full tester guide can be found
212 in README. Among other, most of GeoSPARQL compliance tests
213 (, pg. 53) have been
214 implemented.
216 * Changed the definition and implementation of strdf:distance function, by
217 adopting the definition of GeoSPARQL.
218 (bug #23:
220 * Changed the definition and implementation of strdf:buffer function, by
221 adopting the definition of GeoSPARQL.
222 (bug #35:
224 * Added geof:distance and geof:buffer functions, which have the same definition
225 with strdf:distance and strdf:buffer respectively.
226 (bug #32:
228 * Added a download button when performing describe and construct queries at the
229 endpoint.
230 (bug #38:
232 * Fixed a bug, where XMLWriter and TSVWriter did not return geometries with the
233 SRID.
234 (bug #47:
236 * Fixed a bug where the GeoSPARQL construct functions did not return the datatype
237 geo:wktLiteral datatype but strdf:WKT.
239 Tue Mar 26 13:28:26 2013 Pyravlos Team
241 * Version 3.2.8 released.
243 * Added support for handling (storing/querying) GeoSPARQL datatypes.
244 (bug #31:
246 * Fixed a bug in StoreOp that wouldn't close the connection, neither
247 rollback the transaction upon an exception. This had as a side effect
248 the abnormal termination of StoreOp (through for example the use of
249 Ctrl-C signal) which was leaving the database locked.
251 * Fixed bug where spatial aggregates (e.g., union) didn't work as
252 expected when the query didn't contain a `GROUP BY' clause.
253 (bug #22:
255 * Updated GeoSPARQL namespaces and fixed function names to comply with
256 the GeoSPARQL specification.
257 (bug #25:
259 Wed Jan 09 18:06:41 2013 Pyravlos Team
261 * Version 3.2.7 released.
263 * Add an extension function
264 <> for computing the
265 span (in milliseconds) between two timestamps.
267 * Added an <endpoint-exec> module. This module builds an executable jar file
268 with an embedded Apache Tomcat 7. To create and run the executable jar just
269 type:
270 $ mvn clean package
271 $ java -jar endpoint-exec/target/strabon-endpoint-executable-*.jar
273 * Modified strabon script and postgis/monetdb.StoreOP class to get an
274 option for storing a RDF file in a named graph. Moreover, the RDF
275 format of the input RDF file now is given as an option (still, if it
276 is missing, it is assumed that the input is in N-TRIPLES format). The
277 option for the format is -f and the option for the named graph is -g
278 (takes a URI as an argument).
280 * Modified the names of the stSPARQL extension functions that
281 utilize the minimum bounding boxes of the involved geometries.
283 Tue Dec 11 19:33:45 2012 Pyravlos Team
285 * Version 3.2.6 released.
287 * Modified the names of the stSPARQL extension functions to comply
288 with the OGC Simple Features Access standard.
290 Tue Dec 11 00:11:43 2012 Pyravlos Team
292 * Version 3.2.5 released.
294 * Added support for querying temporal information. This functionality
295 may be found in the `temporals' branch.
297 The datatypes <> and
298 <> are used to
299 represent periods and instants respectively.
301 The valid time time of triples is represented using quadtruples,
302 with the valid time annotation(instant or period) being the
303 fourth element of the quad. In the same way, temporal triple
304 patterns are used in queries to retrieve the valid time of
305 triples.
307 Some functions have been renamed (their URIs have changed) to
308 follow the names of the respective relations of Allen's
309 interval algebra and other functions have been added.
311 The following temporal functions are supported:
312 during, periodOverlaps, equalsPeriod, nequalsPeriod, adjacent,
313 before, after, overleft, overright, meets, starts, finishes,
314 period_intersect, period_union, preceding_period, and
315 succeeding_period.
317 * Changed behaviour of Strabon and Strabon Endpoint for connecting to
318 a spatially-enabled database. Only one instance of Strabon is allowed
319 at a time.
321 * Implemented a Java client for Strabon Endpoint. The client should be
322 used only with endpoint versions >=3.2.5. The implementation may be
323 found int the `endpoint-client' submodule of maven. Currently, only
324 querying of Strabon Endpoints is supported.
326 * Added support for requesting the capabilities of Strabon Endpoint
327 (fixes Bug #20 <>). See
328 changesets f840796400bf and ?<TBC>? for specific details and how you
329 can determine the capabilities of older endpoints (versions <= 3.2.4).
331 * Updated KML writer to include the projected variables of an stSPARQL
332 query in "ExtendedData" and "Data" tags. This is the proper way to
333 do it if we need to convert a KML to a ESRI shapefile and also include
334 such information as attributes for a feature. See related pages from
335 KML specification:
336 <>
337 <>
339 * Added user authentication for storing RDF data through Strabon
340 Endpoint. The credentials are specified in
341 WEB-INF/ file.
343 * Strabon Endpoints now limits the number of the results to a maximum
344 one. The maximum number is specified in the beans.xml file. This
345 corresponds to parameter "maxLimit". The endpoint script has also been
346 updated correspondingly; the limit can be given using the option "-l".
347 One can disable limiting of query results, by setting the "maxLimit"
348 parameter to 0. Addresses Bug #6
349 (<>).
351 * Added "Known Issues" section to README.
353 * Added -m (more memory) and -M (much more memory) options in strabon
354 script for out-of-memory exceptions.
356 * Fixed Bug #10 (<>). Now
357 KMLWriter handles more geometric types (other than polygons). See
358 changeset 9a3bfee64a39.
360 * Menu and navigation in Strabon Endpoint has changed to use jquery.
361 The menu is now populated using the queries placed inside the beans.xml.
363 * Added BrowseBean and browse.jsp for browsing the RDF data using the
364 Strabon Endpoint.
