1 * Fixed a bug where strdf:intersection function did not work as an
2 aggregate when used without 'GROUP BY'.

5 Sat Oct 19 23:37:23 2013 Pyravlos Team
7 * Version 3.2.9 released.
9 * Added support for the following google chart types: PieChart,
10 AreaChart and ColumnChart to strabon endpoint.
12 * Added Timemap as new results format in Strabon endpoint. This
13 option displays results in a map and a timeline on the same time,
14 using the Timemap js library (
15 The KMLWriter has been extended for that purpose, by transforming
16 dateTime values that are included in the result set into the respective
17 TimeStamp KML primitive (
18 In the "temporals" branch, the values of the strdf:period datatype
19 are converted into the respective KML TimeSpan primitive.
21 * Added extension function <> which is
22 mapped to the ST_Centroid(geometry) extension function of PostGIS.
23 See also: <>.
25 * Added extension function <> which is
26 mapped to the ST_MakeLine(geometry, geometry) extension function of
27 PostGIS. See also: <>.
29 * Added PostGIS vocabulary class.
31 * Added support of all SPARQL result types provided by Sesame (json,
32 xml, csv, tsv, binary). To get the respective writer, just prepend the
33 string "SPARQL/", e.g., "SPARQL/JSON". This is to ensure that we
34 support all SPARQL result formats of the SPARQL Protocol.
36 * Fixed a bug where a non-implemented extension function would make
37 Strabon throw a NULL pointer exception. Now we get away with it
38 through a warning.
40 * Strabon endpoint now publishes the URIs of the supported units of
41 measure for use in strdf:distance and geof:distance functions of
42 stSPARQL and GeoSPARQL, respectively. The URIs are those defined by
43 OGC Units of Measure 1.0 specification which may be found at
44 Strabon endpoint publishes
45 the URIs at http://localhost:8080/endpoint/Capabilities.
47 * Created new module with name 'vocab` and artifactId
48 'strabon-vocabulary` and moved there. Other
49 vocabularies have been added as well, such as Simple Features, and
52 * Strabon endpoint now publishes the URIs of the supported extension
53 functions for stSPARQL and GeoSPARQL. One should access them by
54 hitting the link http://localhost:8080/endpoint/Capabilities.
56 * Support for parsing EPSG URIs in geometry literals with datatype
57 geo:wktLiteral.
58 (bug #33:
60 * Endpoint Client now supports querying of Virtuoso and Parliament endpoints.
62 * Endpoint Client now supports store and update operations, but only
63 for Strabon Endpoints.
65 * GeoSPARQL functions sfCrosses, sfOverlaps, ehOverlaps do not use the
66 ST_Relate PostGIS function (bug #24:
68 * All Simple Features functions of GeoSPARQL do not use the ST_Relate
69 PostGIS function
71 * Added diffTime function. This function performs the difference
72 between two literals of xsd:time datatype and returns a literal of
73 the xsd:time datatype as well.
75 * Added a testsuite package in default branch. Full tester guide can be found
76 in README. Among other, most of GeoSPARQL compliance tests
77 (, pg. 53) have been
78 implemented.
80 * Changed the definition and implementation of strdf:distance function, by
81 adopting the definition of GeoSPARQL.
82 (bug #23:
84 * Changed the definition and implementation of strdf:buffer function, by
85 adopting the definition of GeoSPARQL.
86 (bug #35:
88 * Added geof:distance and geof:buffer functions, which have the same definition
89 with strdf:distance and strdf:buffer respectively.
90 (bug #32:
92 * Added a download button when performing describe and construct queries at the
93 endpoint.
94 (bug #38:
96 * Fixed a bug, where XMLWriter and TSVWriter did not return geometries with the
97 SRID.
98 (bug #47:
100 * Fixed a bug where the GeoSPARQL construct functions did not return the datatype
101 geo:wktLiteral datatype but strdf:WKT.
103 Tue Mar 26 13:28:26 2013 Pyravlos Team
105 * Version 3.2.8 released.
107 * Added support for handling (storing/querying) GeoSPARQL datatypes.
108 (bug #31:
110 * Fixed a bug in StoreOp that wouldn't close the connection, neither
111 rollback the transaction upon an exception. This had as a side effect
112 the abnormal termination of StoreOp (through for example the use of
113 Ctrl-C signal) which was leaving the database locked.
115 * Fixed bug where spatial aggregates (e.g., union) didn't work as
116 expected when the query didn't contain a `GROUP BY' clause.
117 (bug #22:
119 * Updated GeoSPARQL namespaces and fixed function names to comply with
120 the GeoSPARQL specification.
121 (bug #25:
123 Wed Jan 09 18:06:41 2013 Pyravlos Team
125 * Version 3.2.7 released.
127 * Add an extension function
128 <> for computing the
129 span (in milliseconds) between two timestamps.
131 * Added an <endpoint-exec> module. This module builds an executable jar file
132 with an embedded Apache Tomcat 7. To create and run the executable jar just
133 type:
134 $ mvn clean package
135 $ java -jar endpoint-exec/target/strabon-endpoint-executable-*.jar
137 * Modified strabon script and postgis/monetdb.StoreOP class to get an
138 option for storing a RDF file in a named graph. Moreover, the RDF
139 format of the input RDF file now is given as an option (still, if it
140 is missing, it is assumed that the input is in N-TRIPLES format). The
141 option for the format is -f and the option for the named graph is -g
142 (takes a URI as an argument).
144 * Modified the names of the stSPARQL extension functions that
145 utilize the minimum bounding boxes of the involved geometries.
147 Tue Dec 11 19:33:45 2012 Pyravlos Team
149 * Version 3.2.6 released.
151 * Modified the names of the stSPARQL extension functions to comply
152 with the OGC Simple Features Access standard.
154 Tue Dec 11 00:11:43 2012 Pyravlos Team
156 * Version 3.2.5 released.
158 * Added support for querying temporal information. This functionality
159 may be found in the `temporals' branch.
161 The datatypes <> and
162 <> are used to
163 represent periods and instants respectively.
165 The valid time time of triples is represented using quadtruples,
166 with the valid time annotation(instant or period) being the
167 fourth element of the quad. In the same way, temporal triple
168 patterns are used in queries to retrieve the valid time of
169 triples.
171 Some functions have been renamed (their URIs have changed) to
172 follow the names of the respective relations of Allen's
173 interval algebra and other functions have been added.
175 The following temporal functions are supported:
176 during, periodOverlaps, equalsPeriod, nequalsPeriod, adjacent,
177 before, after, overleft, overright, meets, starts, finishes,
178 period_intersect, period_union, preceding_period, and
179 succeeding_period.
181 * Changed behaviour of Strabon and Strabon Endpoint for connecting to
182 a spatially-enabled database. Only one instance of Strabon is allowed
183 at a time.
185 * Implemented a Java client for Strabon Endpoint. The client should be
186 used only with endpoint versions >=3.2.5. The implementation may be
187 found int the `endpoint-client' submodule of maven. Currently, only
188 querying of Strabon Endpoints is supported.
190 * Added support for requesting the capabilities of Strabon Endpoint
191 (fixes Bug #20 <>). See
192 changesets f840796400bf and ?<TBC>? for specific details and how you
193 can determine the capabilities of older endpoints (versions <= 3.2.4).
195 * Updated KML writer to include the projected variables of an stSPARQL
196 query in "ExtendedData" and "Data" tags. This is the proper way to
197 do it if we need to convert a KML to a ESRI shapefile and also include
198 such information as attributes for a feature. See related pages from
199 KML specification:
200 <>
201 <>
203 * Added user authentication for storing RDF data through Strabon
204 Endpoint. The credentials are specified in
205 WEB-INF/ file.
207 * Strabon Endpoints now limits the number of the results to a maximum
208 one. The maximum number is specified in the beans.xml file. This
209 corresponds to parameter "maxLimit". The endpoint script has also been
210 updated correspondingly; the limit can be given using the option "-l".
211 One can disable limiting of query results, by setting the "maxLimit"
212 parameter to 0. Addresses Bug #6
213 (<>).
215 * Added "Known Issues" section to README.
217 * Added -m (more memory) and -M (much more memory) options in strabon
218 script for out-of-memory exceptions.
220 * Fixed Bug #10 (<>). Now
221 KMLWriter handles more geometric types (other than polygons). See
222 changeset 9a3bfee64a39.
224 * Menu and navigation in Strabon Endpoint has changed to use jquery.
225 The menu is now populated using the queries placed inside the beans.xml.
227 * Added BrowseBean and browse.jsp for browsing the RDF data using the
228 Strabon Endpoint.
