1 * Bug #58: Added dependencies - java, postgresql, tomcat. Also, added
2 a strabon-init script that detects the postgis installation path
3 and sets up the template_postgis. Finally the script creates a db
4 called "endpoint" (assuming it does not already exist) that is used
5 for the strabon-endpoint command.
7 * Fixed a bug that would return no results when a variable that results
8 from a BIND clause appears in the FILTER or in the projection of a
9 query and is inside a spatial function.
10 (bug #78: http://bug.strabon.di.uoa.gr/ticket/78)
12 * Fixed the precision of the geometry literals in GeoJSON writer. Now,
13 this defaults to the precision model of JTS (equals to 16). Prior to
14 this it was fixed to 4.
16 * Now the GeoJSON writer is aware of the kind of typed literals (e.g.,
17 numeric, boolean, calendar, etc.) and prints the corresponding
18 values according to these types.
20 * Fixed a bug that would not return the correct result or would fail
21 when a spatial function involved a constant and a variable.
22 (bug #74: http://bug.strabon.di.uoa.gr/ticket/74)
24 * Fixed a bug that would not return the correct spatial datatype of a
25 projected geometry literal stored in the database.
26 (bug #71: http://bug.strabon.di.uoa.gr/ticket/71)
28 * Now, geometries expressed in CRS84 and a `geo:wktLiteral' datatype
29 are assigned the correct CRS, i.e., EPSG:4326 with a longitude
30 latitude axis order.
32 * Now, we report a parse error when a constant geometry given in a
33 SELECT or HAVING clause is not well-formed according to the WKT
34 specification.
35 (bug #69: http://bug.strabon.di.uoa.gr/ticket/69)
37 * Function `geof:convexHull' is now supported in a Having clause.
39 * Fixed older implementation of `strdf:distance' that would expect two
40 arguments instead of three when present in a HAVING clause.
42 * Fixed a bug that would cause a class cast exception for grounded
43 expressions with function nesting in the SELECT or HAVING clause.
45 * Fixed a bug in which `postgis:ST_Centroid' did not work in the SELECT
46 clause with input geometries from the database.
48 * Fixed a bug that `geof:getSRID' would return an integer instead of a
49 the URI corrresponding to the CRS that the input geometry was
50 expressed.
51 (bug #32: http://bug.strabon.di.uoa.gr/ticket/32)
53 * Fixed a bug that would raise an exception for queries involving two
54 UNION graph patterns and a projection to a predicate or a URI in
55 general.
56 (bug #53: http://bug.strabon.di.uoa.gr/ticket/53)
58 Wed Sep 17 20:14:12 2014 Pyravlos Team
60 * Version 3.2.10 released.
62 * The test suite of Strabon has now reached a mature level. It
63 contains tests for both stSPARQL and GeoSPARQL query languages and
64 most of the compliance tests covered in the specification of
65 GeoSPARQL (well, only those tests for the components that we have
66 chosen to implement).
68 * The endpoint now parses Accept headers with multiple values and uses
69 the first mimetype corresponding to a valid stSPARQLQueryResultFormat.
70 (bug #64: http://bug.strabon.di.uoa.gr/ticket/64)
72 * The endpoint now registers a handler for SIGTERM signals, so that if
73 it is run from the command-line (endpoint-exec), then the closing of
74 the connection will be ultimately called.
75 (bug #40: http://bug.strabon.di.uoa.gr/ticket/40)
77 * Strabon goes debian v1. the endpoint-exec jar is now given in a .deb
78 format. By dpkg-ing it, one can run a stand alone strabon endpoint
79 locally.
80 (bug #45 http://bug.strabon.di.uoa.gr/ticket/58)
82 * Fixed a bug in which Strabon hanged when a unary spatial construct
83 had a ternary spatial construct as argument.
84 (bug #45 http://bug.strabon.di.uoa.gr/ticket/45)
86 * Fixed a bug according to which spatial functions in ORDER BY were not
87 evaluated at all.
88 (bug #62: http://bug.strabon.di.uoa.gr/ticket/62)
90 * Fixed a bug according to which spatial boolean functions appearing
91 in the SELECT clause were raising a NULL pointer exception.
92 (bug #34: http://bug.strabon.di.uoa.gr/ticket/34)
94 * Fixed a bug in queries that contain variables that exist inside
95 spatial functions in select and do not exist in the where clause
96 made Strabon throw a NULL pointer exception.
97 (bug #51 https://bug.strabon.di.uoa.gr/ticket/51)
99 * Various changes in the interface and behavior of Strabon Endpoint:
100 - Revised the logos and the sample queries.
101 - Results query limit is set to zero (unlimited).
102 - Users can now store RDF data that is present in a file on the
103 client side (the file is uploaded to the server).
104 - Credentials are now required for uploading files or executing
105 UPDATE queries, unless Strabon Endpoint runs locally (localhost).
106 - When viewing the results of queries in HTML, any URI is now an
107 active link to itself. Previously, that URI was being DESCRIBEd
108 and one was being transferred to a page viewing the result of the
109 DESCRIBE query.
110 - The DESCRIBE functionality can now be accessed through the menu bar.
112 * Fixed a bug where strdf:intersection function did not work as an
113 aggregate when used without 'GROUP BY'.
114 (bug #46 https://bug.strabon.di.uoa.gr/ticket/46)
117 Sat Oct 19 23:37:23 2013 Pyravlos Team
119 * Version 3.2.9 released.
121 * Added support for the following google chart types: PieChart,
122 AreaChart and ColumnChart to strabon endpoint.
124 * Added Timemap as new results format in Strabon endpoint. This
125 option displays results in a map and a timeline on the same time,
126 using the Timemap js library (http://code.google.com/p/timemap/).
127 The KMLWriter has been extended for that purpose, by transforming
128 dateTime values that are included in the result set into the respective
129 TimeStamp KML primitive (https://developers.google.com/kml/documentation/time).
130 In the "temporals" branch, the values of the strdf:period datatype
131 are converted into the respective KML TimeSpan primitive.
133 * Added extension function <http://postgis.net/ST_Centroid> which is
134 mapped to the ST_Centroid(geometry) extension function of PostGIS.
135 See also: <http://postgis.org/docs/ST_Centroid.html>.
137 * Added extension function <http://postgis.net/ST_MakeLine> which is
138 mapped to the ST_MakeLine(geometry, geometry) extension function of
139 PostGIS. See also: <http://postgis.org/docs/ST_MakeLine.html>.
141 * Added PostGIS vocabulary class.
143 * Added support of all SPARQL result types provided by Sesame (json,
144 xml, csv, tsv, binary). To get the respective writer, just prepend the
145 string "SPARQL/", e.g., "SPARQL/JSON". This is to ensure that we
146 support all SPARQL result formats of the SPARQL Protocol.
148 * Fixed a bug where a non-implemented extension function would make
149 Strabon throw a NULL pointer exception. Now we get away with it
150 through a warning.
152 * Strabon endpoint now publishes the URIs of the supported units of
153 measure for use in strdf:distance and geof:distance functions of
154 stSPARQL and GeoSPARQL, respectively. The URIs are those defined by
155 OGC Units of Measure 1.0 specification which may be found at
156 http://www.opengis.net/def/uom/OGC/1.0/. Strabon endpoint publishes
157 the URIs at http://localhost:8080/endpoint/Capabilities.
159 * Created new module with name 'vocab` and artifactId
160 'strabon-vocabulary` and moved GeoConstants.java there. Other
161 vocabularies have been added as well, such as Simple Features, and
162 GeoSPARQL.
164 * Strabon endpoint now publishes the URIs of the supported extension
165 functions for stSPARQL and GeoSPARQL. One should access them by
166 hitting the link http://localhost:8080/endpoint/Capabilities.
168 * Support for parsing EPSG URIs in geometry literals with datatype
169 geo:wktLiteral.
170 (bug #33: http://bug.strabon.di.uoa.gr/ticket/33)
172 * Endpoint Client now supports querying of Virtuoso and Parliament endpoints.
174 * Endpoint Client now supports store and update operations, but only
175 for Strabon Endpoints.
177 * GeoSPARQL functions sfCrosses, sfOverlaps, ehOverlaps do not use the
178 ST_Relate PostGIS function (bug #24: http://bug.strabon.di.uoa.gr/ticket/24)
180 * All Simple Features functions of GeoSPARQL do not use the ST_Relate
181 PostGIS function
183 * Added diffTime function. This function performs the difference
184 between two literals of xsd:time datatype and returns a literal of
185 the xsd:time datatype as well.
187 * Added a testsuite package in default branch. Full tester guide can be found
188 in README. Among other, most of GeoSPARQL compliance tests
189 (https://portal.opengeospatial.org/files/?artifact_id=47664, pg. 53) have been
190 implemented.
192 * Changed the definition and implementation of strdf:distance function, by
193 adopting the definition of GeoSPARQL.
194 (bug #23: http://bug.strabon.di.uoa.gr/ticket/23)
196 * Changed the definition and implementation of strdf:buffer function, by
197 adopting the definition of GeoSPARQL.
198 (bug #35: http://bug.strabon.di.uoa.gr/ticket/35)
200 * Added geof:distance and geof:buffer functions, which have the same definition
201 with strdf:distance and strdf:buffer respectively.
202 (bug #32: http://bug.strabon.di.uoa.gr/ticket/32)
204 * Added a download button when performing describe and construct queries at the
205 endpoint.
206 (bug #38: http://bug.strabon.di.uoa.gr/ticket/38)
208 * Fixed a bug, where XMLWriter and TSVWriter did not return geometries with the
209 SRID.
210 (bug #47: http://bug.strabon.di.uoa.gr/ticket/47)
212 * Fixed a bug where the GeoSPARQL construct functions did not return the datatype
213 geo:wktLiteral datatype but strdf:WKT.
215 Tue Mar 26 13:28:26 2013 Pyravlos Team
217 * Version 3.2.8 released.
219 * Added support for handling (storing/querying) GeoSPARQL datatypes.
220 (bug #31: http://bug.strabon.di.uoa.gr/ticket/31)
222 * Fixed a bug in StoreOp that wouldn't close the connection, neither
223 rollback the transaction upon an exception. This had as a side effect
224 the abnormal termination of StoreOp (through for example the use of
225 Ctrl-C signal) which was leaving the database locked.
227 * Fixed bug where spatial aggregates (e.g., union) didn't work as
228 expected when the query didn't contain a `GROUP BY' clause.
229 (bug #22: http://bug.strabon.di.uoa.gr/ticket/22)
231 * Updated GeoSPARQL namespaces and fixed function names to comply with
232 the GeoSPARQL specification.
233 (bug #25: http://bug.strabon.di.uoa.gr/ticket/25)
235 Wed Jan 09 18:06:41 2013 Pyravlos Team
237 * Version 3.2.7 released.
239 * Add an extension function
240 <http://strdf.di.uoa.gr/extensions/ontology#diffDateTime> for computing the
241 span (in milliseconds) between two timestamps.
243 * Added an <endpoint-exec> module. This module builds an executable jar file
244 with an embedded Apache Tomcat 7. To create and run the executable jar just
245 type:
246 $ mvn clean package
247 $ java -jar endpoint-exec/target/strabon-endpoint-executable-*.jar
249 * Modified strabon script and postgis/monetdb.StoreOP class to get an
250 option for storing a RDF file in a named graph. Moreover, the RDF
251 format of the input RDF file now is given as an option (still, if it
252 is missing, it is assumed that the input is in N-TRIPLES format). The
253 option for the format is -f and the option for the named graph is -g
254 (takes a URI as an argument).
256 * Modified the names of the stSPARQL extension functions that
257 utilize the minimum bounding boxes of the involved geometries.
259 Tue Dec 11 19:33:45 2012 Pyravlos Team
261 * Version 3.2.6 released.
263 * Modified the names of the stSPARQL extension functions to comply
264 with the OGC Simple Features Access standard.
266 Tue Dec 11 00:11:43 2012 Pyravlos Team
268 * Version 3.2.5 released.
270 * Added support for querying temporal information. This functionality
271 may be found in the `temporals' branch.
273 The datatypes <http://strdf.di.uoa.gr/ontology#period> and
274 <http://www.w3.org/2001/XMLSchema#dateTime> are used to
275 represent periods and instants respectively.
277 The valid time time of triples is represented using quadtruples,
278 with the valid time annotation(instant or period) being the
279 fourth element of the quad. In the same way, temporal triple
280 patterns are used in queries to retrieve the valid time of
281 triples.
283 Some functions have been renamed (their URIs have changed) to
284 follow the names of the respective relations of Allen's
285 interval algebra and other functions have been added.
287 The following temporal functions are supported:
288 during, periodOverlaps, equalsPeriod, nequalsPeriod, adjacent,
289 before, after, overleft, overright, meets, starts, finishes,
290 period_intersect, period_union, preceding_period, and
291 succeeding_period.
293 * Changed behaviour of Strabon and Strabon Endpoint for connecting to
294 a spatially-enabled database. Only one instance of Strabon is allowed
295 at a time.
297 * Implemented a Java client for Strabon Endpoint. The client should be
298 used only with endpoint versions >=3.2.5. The implementation may be
299 found int the `endpoint-client' submodule of maven. Currently, only
300 querying of Strabon Endpoints is supported.
302 * Added support for requesting the capabilities of Strabon Endpoint
303 (fixes Bug #20 <http://bug.strabon.di.uoa.gr/ticket/20>). See
304 changesets f840796400bf and ?<TBC>? for specific details and how you
305 can determine the capabilities of older endpoints (versions <= 3.2.4).
307 * Updated KML writer to include the projected variables of an stSPARQL
308 query in "ExtendedData" and "Data" tags. This is the proper way to
309 do it if we need to convert a KML to a ESRI shapefile and also include
310 such information as attributes for a feature. See related pages from
311 KML specification:
312 <https://developers.google.com/kml/documentation/kmlreference#extendeddata>
313 <https://developers.google.com/kml/documentation/extendeddata>
315 * Added user authentication for storing RDF data through Strabon
316 Endpoint. The credentials are specified in
317 WEB-INF/credentials.properties file.
319 * Strabon Endpoints now limits the number of the results to a maximum
320 one. The maximum number is specified in the beans.xml file. This
321 corresponds to parameter "maxLimit". The endpoint script has also been
322 updated correspondingly; the limit can be given using the option "-l".
323 One can disable limiting of query results, by setting the "maxLimit"
324 parameter to 0. Addresses Bug #6
325 (<http://bug.strabon.di.uoa.gr/ticket/6>).
327 * Added "Known Issues" section to README.
329 * Added -m (more memory) and -M (much more memory) options in strabon
330 script for out-of-memory exceptions.
332 * Fixed Bug #10 (<http://bug.strabon.di.uoa.gr/ticket/10>). Now
333 KMLWriter handles more geometric types (other than polygons). See
334 changeset 9a3bfee64a39.
336 * Menu and navigation in Strabon Endpoint has changed to use jquery.
337 The menu is now populated using the queries placed inside the beans.xml.
339 * Added BrowseBean and browse.jsp for browsing the RDF data using the
340 Strabon Endpoint.
