3 * Version 3.2.10 released.
5 * Fixed a bug in which Strabon hanged when a unary spatial construct
6 had a ternary spatial construct as argument.
7 (bug #45 http://bug.strabon.di.uoa.gr/ticket/45
9 * Altered default SRID to GeoSPARQL SRID: Geometries with wktLiteral
10 datatype in SPARQL queries were not interpreted in the correct CRS.
11 (bug #44 http://bug.strabon.di.uoa.gr/ticket/44)
13 * Fixed a bug in queries that contain variables that exist inside
14 spatial functions in select and do not exist in the where clause
15 made Strabon throw a NULL pointer exception.
16 (bug #51 https://bug.strabon.di.uoa.gr/ticket/51)
18 * Various changes in the interface and behavior of Strabon Endpoint:
19 - Revised the logos and the sample queries.
20 - Results query limit is set to zero (unlimited).
21 - Users can now store RDF data that is present in a file on the
22 client side (the file is uploaded to the server).
23 - Credentials are now required for uploading files or executing
24 UPDATE queries, unless Strabon Endpoint runs locally (localhost).
25 - When viewing the results of queries in HTML, any URI is now an
26 active link to itself. Previously, that URI was being DESCRIBEd
27 and one was being transferred to a page viewing the result of the
28 DESCRIBE query.
29 - The DESCRIBE functionality can now be accessed through the menu bar.
31 * Fixed a bug where strdf:intersection function did not work as an
32 aggregate when used without 'GROUP BY'.

36 Sat Oct 19 23:37:23 2013 Pyravlos Team
38 * Version 3.2.9 released.
40 * Added support for the following google chart types: PieChart,
41 AreaChart and ColumnChart to strabon endpoint.
43 * Added Timemap as new results format in Strabon endpoint. This
44 option displays results in a map and a timeline on the same time,
45 using the Timemap js library (http://code.google.com/p/timemap/).
46 The KMLWriter has been extended for that purpose, by transforming
47 dateTime values that are included in the result set into the respective
48 TimeStamp KML primitive (https://developers.google.com/kml/documentation/time).
49 In the "temporals" branch, the values of the strdf:period datatype
50 are converted into the respective KML TimeSpan primitive.
52 * Added extension function <http://postgis.net/ST_Centroid> which is
53 mapped to the ST_Centroid(geometry) extension function of PostGIS.
54 See also: <http://postgis.org/docs/ST_Centroid.html>.
56 * Added extension function <http://postgis.net/ST_MakeLine> which is
57 mapped to the ST_MakeLine(geometry, geometry) extension function of
58 PostGIS. See also: <http://postgis.org/docs/ST_MakeLine.html>.
60 * Added PostGIS vocabulary class.
62 * Added support of all SPARQL result types provided by Sesame (json,
63 xml, csv, tsv, binary). To get the respective writer, just prepend the
64 string "SPARQL/", e.g., "SPARQL/JSON". This is to ensure that we
65 support all SPARQL result formats of the SPARQL Protocol.
67 * Fixed a bug where a non-implemented extension function would make
68 Strabon throw a NULL pointer exception. Now we get away with it
69 through a warning.
71 * Strabon endpoint now publishes the URIs of the supported units of
72 measure for use in strdf:distance and geof:distance functions of
73 stSPARQL and GeoSPARQL, respectively. The URIs are those defined by
74 OGC Units of Measure 1.0 specification which may be found at
75 http://www.opengis.net/def/uom/OGC/1.0/. Strabon endpoint publishes
76 the URIs at http://localhost:8080/endpoint/Capabilities.
78 * Created new module with name 'vocab` and artifactId
79 'strabon-vocabulary` and moved GeoConstants.java there. Other
80 vocabularies have been added as well, such as Simple Features, and
81 GeoSPARQL.
83 * Strabon endpoint now publishes the URIs of the supported extension
84 functions for stSPARQL and GeoSPARQL. One should access them by
85 hitting the link http://localhost:8080/endpoint/Capabilities.
87 * Support for parsing EPSG URIs in geometry literals with datatype
88 geo:wktLiteral.
89 (bug #33: http://bug.strabon.di.uoa.gr/ticket/33)
91 * Endpoint Client now supports querying of Virtuoso and Parliament endpoints.
93 * Endpoint Client now supports store and update operations, but only
94 for Strabon Endpoints.
96 * GeoSPARQL functions sfCrosses, sfOverlaps, ehOverlaps do not use the
97 ST_Relate PostGIS function (bug #24: http://bug.strabon.di.uoa.gr/ticket/24)
99 * All Simple Features functions of GeoSPARQL do not use the ST_Relate
100 PostGIS function
102 * Added diffTime function. This function performs the difference
103 between two literals of xsd:time datatype and returns a literal of
104 the xsd:time datatype as well.
106 * Added a testsuite package in default branch. Full tester guide can be found
107 in README. Among other, most of GeoSPARQL compliance tests
108 (https://portal.opengeospatial.org/files/?artifact_id=47664, pg. 53) have been
109 implemented.
111 * Changed the definition and implementation of strdf:distance function, by
112 adopting the definition of GeoSPARQL.
113 (bug #23: http://bug.strabon.di.uoa.gr/ticket/23)
115 * Changed the definition and implementation of strdf:buffer function, by
116 adopting the definition of GeoSPARQL.
117 (bug #35: http://bug.strabon.di.uoa.gr/ticket/35)
119 * Added geof:distance and geof:buffer functions, which have the same definition
120 with strdf:distance and strdf:buffer respectively.
121 (bug #32: http://bug.strabon.di.uoa.gr/ticket/32)
123 * Added a download button when performing describe and construct queries at the
124 endpoint.
125 (bug #38: http://bug.strabon.di.uoa.gr/ticket/38)
127 * Fixed a bug, where XMLWriter and TSVWriter did not return geometries with the
128 SRID.
129 (bug #47: http://bug.strabon.di.uoa.gr/ticket/47)
131 * Fixed a bug where the GeoSPARQL construct functions did not return the datatype
132 geo:wktLiteral datatype but strdf:WKT.
134 Tue Mar 26 13:28:26 2013 Pyravlos Team
136 * Version 3.2.8 released.
138 * Added support for handling (storing/querying) GeoSPARQL datatypes.
139 (bug #31: http://bug.strabon.di.uoa.gr/ticket/31)
141 * Fixed a bug in StoreOp that wouldn't close the connection, neither
142 rollback the transaction upon an exception. This had as a side effect
143 the abnormal termination of StoreOp (through for example the use of
144 Ctrl-C signal) which was leaving the database locked.
146 * Fixed bug where spatial aggregates (e.g., union) didn't work as
147 expected when the query didn't contain a `GROUP BY' clause.
148 (bug #22: http://bug.strabon.di.uoa.gr/ticket/22)
150 * Updated GeoSPARQL namespaces and fixed function names to comply with
151 the GeoSPARQL specification.
152 (bug #25: http://bug.strabon.di.uoa.gr/ticket/25)
154 Wed Jan 09 18:06:41 2013 Pyravlos Team
156 * Version 3.2.7 released.
158 * Add an extension function
159 <http://strdf.di.uoa.gr/extensions/ontology#diffDateTime> for computing the
160 span (in milliseconds) between two timestamps.
162 * Added an <endpoint-exec> module. This module builds an executable jar file
163 with an embedded Apache Tomcat 7. To create and run the executable jar just
164 type:
165 $ mvn clean package
166 $ java -jar endpoint-exec/target/strabon-endpoint-executable-*.jar
168 * Modified strabon script and postgis/monetdb.StoreOP class to get an
169 option for storing a RDF file in a named graph. Moreover, the RDF
170 format of the input RDF file now is given as an option (still, if it
171 is missing, it is assumed that the input is in N-TRIPLES format). The
172 option for the format is -f and the option for the named graph is -g
173 (takes a URI as an argument).
175 * Modified the names of the stSPARQL extension functions that
176 utilize the minimum bounding boxes of the involved geometries.
178 Tue Dec 11 19:33:45 2012 Pyravlos Team
180 * Version 3.2.6 released.
182 * Modified the names of the stSPARQL extension functions to comply
183 with the OGC Simple Features Access standard.
185 Tue Dec 11 00:11:43 2012 Pyravlos Team
187 * Version 3.2.5 released.
189 * Added support for querying temporal information. This functionality
190 may be found in the `temporals' branch.
192 The datatypes <http://strdf.di.uoa.gr/ontology#period> and
193 <http://www.w3.org/2001/XMLSchema#dateTime> are used to
194 represent periods and instants respectively.
196 The valid time time of triples is represented using quadtruples,
197 with the valid time annotation(instant or period) being the
198 fourth element of the quad. In the same way, temporal triple
199 patterns are used in queries to retrieve the valid time of
200 triples.
202 Some functions have been renamed (their URIs have changed) to
203 follow the names of the respective relations of Allen's
204 interval algebra and other functions have been added.
206 The following temporal functions are supported:
207 during, periodOverlaps, equalsPeriod, nequalsPeriod, adjacent,
208 before, after, overleft, overright, meets, starts, finishes,
209 period_intersect, period_union, preceding_period, and
210 succeeding_period.
212 * Changed behaviour of Strabon and Strabon Endpoint for connecting to
213 a spatially-enabled database. Only one instance of Strabon is allowed
214 at a time.
216 * Implemented a Java client for Strabon Endpoint. The client should be
217 used only with endpoint versions >=3.2.5. The implementation may be
218 found int the `endpoint-client' submodule of maven. Currently, only
219 querying of Strabon Endpoints is supported.
221 * Added support for requesting the capabilities of Strabon Endpoint
222 (fixes Bug #20 <http://bug.strabon.di.uoa.gr/ticket/20>). See
223 changesets f840796400bf and ?<TBC>? for specific details and how you
224 can determine the capabilities of older endpoints (versions <= 3.2.4).
226 * Updated KML writer to include the projected variables of an stSPARQL
227 query in "ExtendedData" and "Data" tags. This is the proper way to
228 do it if we need to convert a KML to a ESRI shapefile and also include
229 such information as attributes for a feature. See related pages from
230 KML specification:
231 <https://developers.google.com/kml/documentation/kmlreference#extendeddata>
232 <https://developers.google.com/kml/documentation/extendeddata>
234 * Added user authentication for storing RDF data through Strabon
235 Endpoint. The credentials are specified in
236 WEB-INF/credentials.properties file.
238 * Strabon Endpoints now limits the number of the results to a maximum
239 one. The maximum number is specified in the beans.xml file. This
240 corresponds to parameter "maxLimit". The endpoint script has also been
241 updated correspondingly; the limit can be given using the option "-l".
242 One can disable limiting of query results, by setting the "maxLimit"
243 parameter to 0. Addresses Bug #6
244 (<http://bug.strabon.di.uoa.gr/ticket/6>).
246 * Added "Known Issues" section to README.
248 * Added -m (more memory) and -M (much more memory) options in strabon
249 script for out-of-memory exceptions.
251 * Fixed Bug #10 (<http://bug.strabon.di.uoa.gr/ticket/10>). Now
252 KMLWriter handles more geometric types (other than polygons). See
253 changeset 9a3bfee64a39.
255 * Menu and navigation in Strabon Endpoint has changed to use jquery.
256 The menu is now populated using the queries placed inside the beans.xml.
258 * Added BrowseBean and browse.jsp for browsing the RDF data using the
259 Strabon Endpoint.
