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 * Changed the definition and implementation of strdf:distance function, by
72 adopting the definition of GeoSPARQL.
73 (bug #23:
75 * Changed the definition and implementation of strdf:buffer function, by
76 adopting the definition of GeoSPARQL.
77 (bug #35:
79 * Added geof:distance and geof:buffer functions, which have the same definition
80 with strdf:distance and strdf:buffer respectively.
82 * Fixed a bug where the GeoSPARQL construct functions did not return the datatype
83 geo:wktLiteral datatype but strdf:WKT.
85 Tue Mar 26 13:28:26 2013 Pyravlos Team
87 * Version 3.2.8 released.
89 * Added support for handling (storing/querying) GeoSPARQL datatypes.
90 (bug #31:
92 * Fixed a bug in StoreOp that wouldn't close the connection, neither
93 rollback the transaction upon an exception. This had as a side effect
94 the abnormal termination of StoreOp (through for example the use of
95 Ctrl-C signal) which was leaving the database locked.
97 * Fixed bug where spatial aggregates (e.g., union) didn't work as
98 expected when the query didn't contain a `GROUP BY' clause.
99 (bug #22:
101 * Updated GeoSPARQL namespaces and fixed function names to comply with
102 the GeoSPARQL specification.
103 (bug #25:
105 Wed Jan 09 18:06:41 2013 Pyravlos Team
107 * Version 3.2.7 released.
109 * Add an extension function
110 <> for computing the
111 span (in milliseconds) between two timestamps.
113 * Added an <endpoint-exec> module. This module builds an executable jar file
114 with an embedded Apache Tomcat 7. To create and run the executable jar just
115 type:
116 $ mvn clean package
117 $ java -jar endpoint-exec/target/strabon-endpoint-executable-*.jar
119 * Modified strabon script and postgis/monetdb.StoreOP class to get an
120 option for storing a RDF file in a named graph. Moreover, the RDF
121 format of the input RDF file now is given as an option (still, if it
122 is missing, it is assumed that the input is in N-TRIPLES format). The
123 option for the format is -f and the option for the named graph is -g
124 (takes a URI as an argument).
126 * Modified the names of the stSPARQL extension functions that
127 utilize the minimum bounding boxes of the involved geometries.
129 Tue Dec 11 19:33:45 2012 Pyravlos Team
131 * Version 3.2.6 released.
133 * Modified the names of the stSPARQL extension functions to comply
134 with the OGC Simple Features Access standard.
136 Tue Dec 11 00:11:43 2012 Pyravlos Team
138 * Version 3.2.5 released.
140 * Added support for querying temporal information. This functionality
141 may be found in the `temporals' branch.
143 The datatypes <> and
144 <> are used to
145 represent periods and instants respectively.
147 The valid time time of triples is represented using quadtruples,
148 with the valid time annotation(instant or period) being the
149 fourth element of the quad. In the same way, temporal triple
150 patterns are used in queries to retrieve the valid time of
151 triples.
153 Some functions have been renamed (their URIs have changed) to
154 follow the names of the respective relations of Allen's
155 interval algebra and other functions have been added.
157 The following temporal functions are supported:
158 during, periodOverlaps, equalsPeriod, nequalsPeriod, adjacent,
159 before, after, overleft, overright, meets, starts, finishes,
160 period_intersect, period_union, preceding_period, and
161 succeeding_period.
163 * Changed behaviour of Strabon and Strabon Endpoint for connecting to
164 a spatially-enabled database. Only one instance of Strabon is allowed
165 at a time.
167 * Implemented a Java client for Strabon Endpoint. The client should be
168 used only with endpoint versions >=3.2.5. The implementation may be
169 found int the `endpoint-client' submodule of maven. Currently, only
170 querying of Strabon Endpoints is supported.
172 * Added support for requesting the capabilities of Strabon Endpoint
173 (fixes Bug #20 <>). See
174 changesets f840796400bf and ?<TBC>? for specific details and how you
175 can determine the capabilities of older endpoints (versions <= 3.2.4).
177 * Updated KML writer to include the projected variables of an stSPARQL
178 query in "ExtendedData" and "Data" tags. This is the proper way to
179 do it if we need to convert a KML to a ESRI shapefile and also include
180 such information as attributes for a feature. See related pages from
181 KML specification:
182 <>
183 <>
185 * Added user authentication for storing RDF data through Strabon
186 Endpoint. The credentials are specified in
187 WEB-INF/ file.
189 * Strabon Endpoints now limits the number of the results to a maximum
190 one. The maximum number is specified in the beans.xml file. This
191 corresponds to parameter "maxLimit". The endpoint script has also been
192 updated correspondingly; the limit can be given using the option "-l".
193 One can disable limiting of query results, by setting the "maxLimit"
194 parameter to 0. Addresses Bug #6
195 (<>).
197 * Added "Known Issues" section to README.
199 * Added -m (more memory) and -M (much more memory) options in strabon
200 script for out-of-memory exceptions.
202 * Fixed Bug #10 (<>). Now
203 KMLWriter handles more geometric types (other than polygons). See
204 changeset 9a3bfee64a39.
206 * Menu and navigation in Strabon Endpoint has changed to use jquery.
207 The menu is now populated using the queries placed inside the beans.xml.
209 * Added BrowseBean and browse.jsp for browsing the RDF data using the
210 Strabon Endpoint.
