3 * Version 3.2.9 released.
5 * Added support for the following google chart types: PieChart,
6 AreaChart and ColumnChart to strabon endpoint.
8 * Added Timemap as new results format in Strabon endpoint. This
9 option displays results in a map and a timeline on the same time,
10 using the Timemap js library (
11 The KMLWriter has been extended for that purpose, by transforming
12 dateTime values that are included in the result set into the respective
13 TimeStamp KML primitive (
14 In the "temporals" branch, the values of the strdf:period datatype
15 are converted into the respective KML TimeSpan primitive.
17 * Added extension function <> which is
18 mapped to the ST_Centroid(geometry) extension function of PostGIS.
19 See also: <>.
21 * Added extension function <> which is
22 mapped to the ST_MakeLine(geometry, geometry) extension function of
23 PostGIS. See also: <>.
25 * Added PostGIS vocabulary class.
27 * Added support of all SPARQL result types provided by Sesame (json,
28 xml, csv, tsv, binary). To get the respective writer, just prepend the
29 string "SPARQL/", e.g., "SPARQL/JSON". This is to ensure that we
30 support all SPARQL result formats of the SPARQL Protocol.
32 * Fixed a bug where a non-implemented extension function would make
33 Strabon throw a NULL pointer exception. Now we get away with it
34 through a warning.
36 * Strabon endpoint now publishes the URIs of the supported units of
37 measure for use in strdf:distance and geof:distance functions of
38 stSPARQL and GeoSPARQL, respectively. The URIs are those defined by
39 OGC Units of Measure 1.0 specification which may be found at
40 Strabon endpoint publishes
41 the URIs at http://localhost:8080/endpoint/Capabilities.
43 * Created new module with name 'vocab` and artifactId
44 'strabon-vocabulary` and moved there. Other
45 vocabularies have been added as well, such as Simple Features, and
48 * Strabon endpoint now publishes the URIs of the supported extension
49 functions for stSPARQL and GeoSPARQL. One should access them by
50 hitting the link http://localhost:8080/endpoint/Capabilities.
52 * Support for parsing EPSG URIs in geometry literals with datatype
53 geo:wktLiteral.
54 (bug #33:
56 * GeoSPARQL functions sfCrosses, sfOverlaps, ehOverlaps do not use the
57 ST_Relate PostGIS function (bug #24:
59 * All Simple Features functions of GeoSPARQL do not use the ST_Relate
60 PostGIS function
62 * Added diffTime function. This function performs the difference
63 between two literals of xsd:time datatype and returns a literal of
64 the xsd:time datatype as well.
66 * Added a testsuite package in default branch. Full tester guide can be found
67 in README. Among other, most of GeoSPARQL compliance tests
68 (, pg. 53) have been
69 implemented.
71 * Fixed a bug where the GeoSPARQL construct functions did not return the datatype
72 geo:wktLiteral datatype but strdf:WKT.
74 Tue Mar 26 13:28:26 2013 Pyravlos Team
76 * Version 3.2.8 released.
78 * Added support for handling (storing/querying) GeoSPARQL datatypes.
79 (bug #31:
81 * Fixed a bug in StoreOp that wouldn't close the connection, neither
82 rollback the transaction upon an exception. This had as a side effect
83 the abnormal termination of StoreOp (through for example the use of
84 Ctrl-C signal) which was leaving the database locked.
86 * Fixed bug where spatial aggregates (e.g., union) didn't work as
87 expected when the query didn't contain a `GROUP BY' clause.
88 (bug #22:
90 * Updated GeoSPARQL namespaces and fixed function names to comply with
91 the GeoSPARQL specification.
92 (bug #25:
94 Wed Jan 09 18:06:41 2013 Pyravlos Team
96 * Version 3.2.7 released.
98 * Add an extension function
99 <> for computing the
100 span (in milliseconds) between two timestamps.
102 * Added an <endpoint-exec> module. This module builds an executable jar file
103 with an embedded Apache Tomcat 7. To create and run the executable jar just
104 type:
105 $ mvn clean package
106 $ java -jar endpoint-exec/target/strabon-endpoint-executable-*.jar
108 * Modified strabon script and postgis/monetdb.StoreOP class to get an
109 option for storing a RDF file in a named graph. Moreover, the RDF
110 format of the input RDF file now is given as an option (still, if it
111 is missing, it is assumed that the input is in N-TRIPLES format). The
112 option for the format is -f and the option for the named graph is -g
113 (takes a URI as an argument).
115 * Modified the names of the stSPARQL extension functions that
116 utilize the minimum bounding boxes of the involved geometries.
118 Tue Dec 11 19:33:45 2012 Pyravlos Team
120 * Version 3.2.6 released.
122 * Modified the names of the stSPARQL extension functions to comply
123 with the OGC Simple Features Access standard.
125 Tue Dec 11 00:11:43 2012 Pyravlos Team
127 * Version 3.2.5 released.
129 * Added support for querying temporal information. This functionality
130 may be found in the `temporals' branch.
132 The datatypes <> and
133 <> are used to
134 represent periods and instants respectively.
136 The valid time time of triples is represented using quadtruples,
137 with the valid time annotation(instant or period) being the
138 fourth element of the quad. In the same way, temporal triple
139 patterns are used in queries to retrieve the valid time of
140 triples.
142 Some functions have been renamed (their URIs have changed) to
143 follow the names of the respective relations of Allen's
144 interval algebra and other functions have been added.
146 The following temporal functions are supported:
147 during, periodOverlaps, equalsPeriod, nequalsPeriod, adjacent,
148 before, after, overleft, overright, meets, starts, finishes,
149 period_intersect, period_union, preceding_period, and
150 succeeding_period.
152 * Changed behaviour of Strabon and Strabon Endpoint for connecting to
153 a spatially-enabled database. Only one instance of Strabon is allowed
154 at a time.
156 * Implemented a Java client for Strabon Endpoint. The client should be
157 used only with endpoint versions >=3.2.5. The implementation may be
158 found int the `endpoint-client' submodule of maven. Currently, only
159 querying of Strabon Endpoints is supported.
161 * Added support for requesting the capabilities of Strabon Endpoint
162 (fixes Bug #20 <>). See
163 changesets f840796400bf and ?<TBC>? for specific details and how you
164 can determine the capabilities of older endpoints (versions <= 3.2.4).
166 * Updated KML writer to include the projected variables of an stSPARQL
167 query in "ExtendedData" and "Data" tags. This is the proper way to
168 do it if we need to convert a KML to a ESRI shapefile and also include
169 such information as attributes for a feature. See related pages from
170 KML specification:
171 <>
172 <>
174 * Added user authentication for storing RDF data through Strabon
175 Endpoint. The credentials are specified in
176 WEB-INF/ file.
178 * Strabon Endpoints now limits the number of the results to a maximum
179 one. The maximum number is specified in the beans.xml file. This
180 corresponds to parameter "maxLimit". The endpoint script has also been
181 updated correspondingly; the limit can be given using the option "-l".
182 One can disable limiting of query results, by setting the "maxLimit"
183 parameter to 0. Addresses Bug #6
184 (<>).
186 * Added "Known Issues" section to README.
188 * Added -m (more memory) and -M (much more memory) options in strabon
189 script for out-of-memory exceptions.
191 * Fixed Bug #10 (<>). Now
192 KMLWriter handles more geometric types (other than polygons). See
193 changeset 9a3bfee64a39.
195 * Menu and navigation in Strabon Endpoint has changed to use jquery.
196 The menu is now populated using the queries placed inside the beans.xml.
198 * Added BrowseBean and browse.jsp for browsing the RDF data using the
199 Strabon Endpoint.
