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