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