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