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