3 * Bug #73, modified appendBuffer function to take the srid into
4 consideration even if the argument is a constant (wktLiteral
5 or strdf literal)
7 * Update jar references on scripts used by the debian packaging.
8 Previously these references pointed only (incorrectly) to
9 SNAPSHOTs.
11 * Updated package names (since repositories cannot include capital
12 letters + runtime and endpoint-exec must have different names
14 * Version 3.3.1 released.
16 * Bug #58, added script that is invoked my maven to also update the
17 version described in the deb/control file of the runtime and
18 endpoint-exec components.
20 * Related to bug #58, but it generally enhances Strabon; The runtime
21 component has also been debianized. Dependencies are added to
22 /usr/share/jdeb/lib/strabon-runtime. ClassPath and strabon script
23 have also been updated accordingly (strabon-cmd)
25 * Bug #58: Maven creates the debian package conditionally. Use
26 -Ddebian=true in the mvn package command.
28 * Bug #58: Added dependencies - java, postgresql, tomcat. Also, added
29 a strabon-init script that detects the postgis installation path
30 and sets up the template_postgis. Finally the script creates a db
31 called "endpoint" (assuming it does not already exist) that is used
32 for the strabon-endpoint command.
34 * Fixed an issue that returned null SRID when unmarshalling GML geometries if
35 the SRID did not follow one of the supported formats by GML-JTS. To fix that
36 we added a function that handles these cases by reading the userData variable
37 that JTS provides.
39 * Fixed a bug that would return no results when a variable that results
40 from a BIND clause appears in the FILTER or in the projection of a
41 query and is inside a spatial function.
42 (bug #78: http://bug.strabon.di.uoa.gr/ticket/78)
44 * Fixed the precision of the geometry literals in GeoJSON writer. Now,
45 this defaults to the precision model of JTS (equals to 16). Prior to
46 this it was fixed to 4.
48 * Now the GeoJSON writer is aware of the kind of typed literals (e.g.,
49 numeric, boolean, calendar, etc.) and prints the corresponding
50 values according to these types.
52 * Fixed a bug that would not return the correct result or would fail
53 when a spatial function involved a constant and a variable.
54 (bug #74: http://bug.strabon.di.uoa.gr/ticket/74)
56 * Fixed a bug that would not return the correct spatial datatype of a
57 projected geometry literal stored in the database.
58 (bug #71: http://bug.strabon.di.uoa.gr/ticket/71)
60 * Now, geometries expressed in CRS84 and a `geo:wktLiteral' datatype
61 are assigned the correct CRS, i.e., EPSG:4326 with a longitude
62 latitude axis order.
64 * Now, we report a parse error when a constant geometry given in a
65 SELECT or HAVING clause is not well-formed according to the WKT
66 specification.
67 (bug #69: http://bug.strabon.di.uoa.gr/ticket/69)
69 * Function `geof:convexHull' is now supported in a Having clause.
71 * Fixed older implementation of `strdf:distance' that would expect two
72 arguments instead of three when present in a HAVING clause.
74 * Fixed a bug that would cause a class cast exception for grounded
75 expressions with function nesting in the SELECT or HAVING clause.
77 * Fixed a bug in which `postgis:ST_Centroid' did not work in the SELECT
78 clause with input geometries from the database.
80 * Fixed a bug that `geof:getSRID' would return an integer instead of a
81 the URI corrresponding to the CRS that the input geometry was
82 expressed.
83 (bug #32: http://bug.strabon.di.uoa.gr/ticket/32)
85 * Fixed a bug that would raise an exception for queries involving two
86 UNION graph patterns and a projection to a predicate or a URI in
87 general.
88 (bug #53: http://bug.strabon.di.uoa.gr/ticket/53)
90 Wed Sep 17 20:14:12 2014 Pyravlos Team
92 * Version 3.2.10 released.
94 * The test suite of Strabon has now reached a mature level. It
95 contains tests for both stSPARQL and GeoSPARQL query languages and
96 most of the compliance tests covered in the specification of
97 GeoSPARQL (well, only those tests for the components that we have
98 chosen to implement).
100 * The endpoint now parses Accept headers with multiple values and uses
101 the first mimetype corresponding to a valid stSPARQLQueryResultFormat.
102 (bug #64: http://bug.strabon.di.uoa.gr/ticket/64)
104 * The endpoint now registers a handler for SIGTERM signals, so that if
105 it is run from the command-line (endpoint-exec), then the closing of
106 the connection will be ultimately called.
107 (bug #40: http://bug.strabon.di.uoa.gr/ticket/40)
109 * Strabon goes debian v1. the endpoint-exec jar is now given in a .deb
110 format. By dpkg-ing it, one can run a stand alone strabon endpoint
111 locally.
112 (bug #45 http://bug.strabon.di.uoa.gr/ticket/58)
114 * Fixed a bug in which Strabon hanged when a unary spatial construct
115 had a ternary spatial construct as argument.
116 (bug #45 http://bug.strabon.di.uoa.gr/ticket/45)
118 * Fixed a bug according to which spatial functions in ORDER BY were not
119 evaluated at all.
120 (bug #62: http://bug.strabon.di.uoa.gr/ticket/62)
122 * Fixed a bug according to which spatial boolean functions appearing
123 in the SELECT clause were raising a NULL pointer exception.
124 (bug #34: http://bug.strabon.di.uoa.gr/ticket/34)
126 * Fixed a bug in queries that contain variables that exist inside
127 spatial functions in select and do not exist in the where clause
128 made Strabon throw a NULL pointer exception.
129 (bug #51 https://bug.strabon.di.uoa.gr/ticket/51)
131 * Various changes in the interface and behavior of Strabon Endpoint:
132 - Revised the logos and the sample queries.
133 - Results query limit is set to zero (unlimited).
134 - Users can now store RDF data that is present in a file on the
135 client side (the file is uploaded to the server).
136 - Credentials are now required for uploading files or executing
137 UPDATE queries, unless Strabon Endpoint runs locally (localhost).
138 - When viewing the results of queries in HTML, any URI is now an
139 active link to itself. Previously, that URI was being DESCRIBEd
140 and one was being transferred to a page viewing the result of the
141 DESCRIBE query.
142 - The DESCRIBE functionality can now be accessed through the menu bar.
144 * Fixed a bug where strdf:intersection function did not work as an
145 aggregate when used without 'GROUP BY'.
146 (bug #46 https://bug.strabon.di.uoa.gr/ticket/46)
149 Sat Oct 19 23:37:23 2013 Pyravlos Team
151 * Version 3.2.9 released.
153 * Added support for the following google chart types: PieChart,
154 AreaChart and ColumnChart to strabon endpoint.
156 * Added Timemap as new results format in Strabon endpoint. This
157 option displays results in a map and a timeline on the same time,
158 using the Timemap js library (http://code.google.com/p/timemap/).
159 The KMLWriter has been extended for that purpose, by transforming
160 dateTime values that are included in the result set into the respective
161 TimeStamp KML primitive (https://developers.google.com/kml/documentation/time).
162 In the "temporals" branch, the values of the strdf:period datatype
163 are converted into the respective KML TimeSpan primitive.
165 * Added extension function <http://postgis.net/ST_Centroid> which is
166 mapped to the ST_Centroid(geometry) extension function of PostGIS.
167 See also: <http://postgis.org/docs/ST_Centroid.html>.
169 * Added extension function <http://postgis.net/ST_MakeLine> which is
170 mapped to the ST_MakeLine(geometry, geometry) extension function of
171 PostGIS. See also: <http://postgis.org/docs/ST_MakeLine.html>.
173 * Added PostGIS vocabulary class.
175 * Added support of all SPARQL result types provided by Sesame (json,
176 xml, csv, tsv, binary). To get the respective writer, just prepend the
177 string "SPARQL/", e.g., "SPARQL/JSON". This is to ensure that we
178 support all SPARQL result formats of the SPARQL Protocol.
180 * Fixed a bug where a non-implemented extension function would make
181 Strabon throw a NULL pointer exception. Now we get away with it
182 through a warning.
184 * Strabon endpoint now publishes the URIs of the supported units of
185 measure for use in strdf:distance and geof:distance functions of
186 stSPARQL and GeoSPARQL, respectively. The URIs are those defined by
187 OGC Units of Measure 1.0 specification which may be found at
188 http://www.opengis.net/def/uom/OGC/1.0/. Strabon endpoint publishes
189 the URIs at http://localhost:8080/endpoint/Capabilities.
191 * Created new module with name 'vocab` and artifactId
192 'strabon-vocabulary` and moved GeoConstants.java there. Other
193 vocabularies have been added as well, such as Simple Features, and
194 GeoSPARQL.
196 * Strabon endpoint now publishes the URIs of the supported extension
197 functions for stSPARQL and GeoSPARQL. One should access them by
198 hitting the link http://localhost:8080/endpoint/Capabilities.
200 * Support for parsing EPSG URIs in geometry literals with datatype
201 geo:wktLiteral.
202 (bug #33: http://bug.strabon.di.uoa.gr/ticket/33)
204 * Endpoint Client now supports querying of Virtuoso and Parliament endpoints.
206 * Endpoint Client now supports store and update operations, but only
207 for Strabon Endpoints.
209 * GeoSPARQL functions sfCrosses, sfOverlaps, ehOverlaps do not use the
210 ST_Relate PostGIS function (bug #24: http://bug.strabon.di.uoa.gr/ticket/24)
212 * All Simple Features functions of GeoSPARQL do not use the ST_Relate
213 PostGIS function
215 * Added diffTime function. This function performs the difference
216 between two literals of xsd:time datatype and returns a literal of
217 the xsd:time datatype as well.
219 * Added a testsuite package in default branch. Full tester guide can be found
220 in README. Among other, most of GeoSPARQL compliance tests
221 (https://portal.opengeospatial.org/files/?artifact_id=47664, pg. 53) have been
222 implemented.
224 * Changed the definition and implementation of strdf:distance function, by
225 adopting the definition of GeoSPARQL.
226 (bug #23: http://bug.strabon.di.uoa.gr/ticket/23)
228 * Changed the definition and implementation of strdf:buffer function, by
229 adopting the definition of GeoSPARQL.
230 (bug #35: http://bug.strabon.di.uoa.gr/ticket/35)
232 * Added geof:distance and geof:buffer functions, which have the same definition
233 with strdf:distance and strdf:buffer respectively.
234 (bug #32: http://bug.strabon.di.uoa.gr/ticket/32)
236 * Added a download button when performing describe and construct queries at the
237 endpoint.
238 (bug #38: http://bug.strabon.di.uoa.gr/ticket/38)
240 * Fixed a bug, where XMLWriter and TSVWriter did not return geometries with the
241 SRID.
242 (bug #47: http://bug.strabon.di.uoa.gr/ticket/47)
244 * Fixed a bug where the GeoSPARQL construct functions did not return the datatype
245 geo:wktLiteral datatype but strdf:WKT.
247 Tue Mar 26 13:28:26 2013 Pyravlos Team
249 * Version 3.2.8 released.
251 * Added support for handling (storing/querying) GeoSPARQL datatypes.
252 (bug #31: http://bug.strabon.di.uoa.gr/ticket/31)
254 * Fixed a bug in StoreOp that wouldn't close the connection, neither
255 rollback the transaction upon an exception. This had as a side effect
256 the abnormal termination of StoreOp (through for example the use of
257 Ctrl-C signal) which was leaving the database locked.
259 * Fixed bug where spatial aggregates (e.g., union) didn't work as
260 expected when the query didn't contain a `GROUP BY' clause.
261 (bug #22: http://bug.strabon.di.uoa.gr/ticket/22)
263 * Updated GeoSPARQL namespaces and fixed function names to comply with
264 the GeoSPARQL specification.
265 (bug #25: http://bug.strabon.di.uoa.gr/ticket/25)
267 Wed Jan 09 18:06:41 2013 Pyravlos Team
269 * Version 3.2.7 released.
271 * Add an extension function
272 <http://strdf.di.uoa.gr/extensions/ontology#diffDateTime> for computing the
273 span (in milliseconds) between two timestamps.
275 * Added an <endpoint-exec> module. This module builds an executable jar file
276 with an embedded Apache Tomcat 7. To create and run the executable jar just
277 type:
278 $ mvn clean package
279 $ java -jar endpoint-exec/target/strabon-endpoint-executable-*.jar
281 * Modified strabon script and postgis/monetdb.StoreOP class to get an
282 option for storing a RDF file in a named graph. Moreover, the RDF
283 format of the input RDF file now is given as an option (still, if it
284 is missing, it is assumed that the input is in N-TRIPLES format). The
285 option for the format is -f and the option for the named graph is -g
286 (takes a URI as an argument).
288 * Modified the names of the stSPARQL extension functions that
289 utilize the minimum bounding boxes of the involved geometries.
291 Tue Dec 11 19:33:45 2012 Pyravlos Team
293 * Version 3.2.6 released.
295 * Modified the names of the stSPARQL extension functions to comply
296 with the OGC Simple Features Access standard.
298 Tue Dec 11 00:11:43 2012 Pyravlos Team
300 * Version 3.2.5 released.
302 * Added support for querying temporal information. This functionality
303 may be found in the `temporals' branch.
305 The datatypes <http://strdf.di.uoa.gr/ontology#period> and
306 <http://www.w3.org/2001/XMLSchema#dateTime> are used to
307 represent periods and instants respectively.
309 The valid time time of triples is represented using quadtruples,
310 with the valid time annotation(instant or period) being the
311 fourth element of the quad. In the same way, temporal triple
312 patterns are used in queries to retrieve the valid time of
313 triples.
315 Some functions have been renamed (their URIs have changed) to
316 follow the names of the respective relations of Allen's
317 interval algebra and other functions have been added.
319 The following temporal functions are supported:
320 during, periodOverlaps, equalsPeriod, nequalsPeriod, adjacent,
321 before, after, overleft, overright, meets, starts, finishes,
322 period_intersect, period_union, preceding_period, and
323 succeeding_period.
325 * Changed behaviour of Strabon and Strabon Endpoint for connecting to
326 a spatially-enabled database. Only one instance of Strabon is allowed
327 at a time.
329 * Implemented a Java client for Strabon Endpoint. The client should be
330 used only with endpoint versions >=3.2.5. The implementation may be
331 found int the `endpoint-client' submodule of maven. Currently, only
332 querying of Strabon Endpoints is supported.
334 * Added support for requesting the capabilities of Strabon Endpoint
335 (fixes Bug #20 <http://bug.strabon.di.uoa.gr/ticket/20>). See
336 changesets f840796400bf and ?<TBC>? for specific details and how you
337 can determine the capabilities of older endpoints (versions <= 3.2.4).
339 * Updated KML writer to include the projected variables of an stSPARQL
340 query in "ExtendedData" and "Data" tags. This is the proper way to
341 do it if we need to convert a KML to a ESRI shapefile and also include
342 such information as attributes for a feature. See related pages from
343 KML specification:
344 <https://developers.google.com/kml/documentation/kmlreference#extendeddata>
345 <https://developers.google.com/kml/documentation/extendeddata>
347 * Added user authentication for storing RDF data through Strabon
348 Endpoint. The credentials are specified in
349 WEB-INF/credentials.properties file.
351 * Strabon Endpoints now limits the number of the results to a maximum
352 one. The maximum number is specified in the beans.xml file. This
353 corresponds to parameter "maxLimit". The endpoint script has also been
354 updated correspondingly; the limit can be given using the option "-l".
355 One can disable limiting of query results, by setting the "maxLimit"
356 parameter to 0. Addresses Bug #6
357 (<http://bug.strabon.di.uoa.gr/ticket/6>).
359 * Added "Known Issues" section to README.
361 * Added -m (more memory) and -M (much more memory) options in strabon
362 script for out-of-memory exceptions.
364 * Fixed Bug #10 (<http://bug.strabon.di.uoa.gr/ticket/10>). Now
365 KMLWriter handles more geometric types (other than polygons). See
366 changeset 9a3bfee64a39.
368 * Menu and navigation in Strabon Endpoint has changed to use jquery.
369 The menu is now populated using the queries placed inside the beans.xml.
371 * Added BrowseBean and browse.jsp for browsing the RDF data using the
372 Strabon Endpoint.
