3 * Version 3.2.9 released.
5 * Added extension function <http://postgis.net/ST_Centroid> which is
6 mapped to the ST_Centroid(geometry) extension function of PostGIS.
7 See also: <http://postgis.org/docs/ST_Centroid.html>.
9 * Added extension function <http://postgis.net/ST_MakeLine> which is
10 mapped to the ST_MakeLine(geometry, geometry) extension function of
11 PostGIS. See also: <http://postgis.org/docs/ST_MakeLine.html>.
13 * Added PostGIS vocabulary class.
15 * Added support of all SPARQL result types provided by Sesame (json,
16 xml, csv, tsv, binary). To get the respective writer, just prepend the
17 string "SPARQL/", e.g., "SPARQL/JSON". This is to ensure that we
18 support all SPARQL result formats of the SPARQL Protocol.
20 * Fixed a bug where a non-implemented extension function would make
21 Strabon throw a NULL pointer exception. Now we get away with it
22 through a warning.
24 * Strabon endpoint now publishes the URIs of the supported units of
25 measure for use in strdf:distance and geof:distance functions of
26 stSPARQL and GeoSPARQL, respectively. The URIs are those defined by
27 OGC Units of Measure 1.0 specification which may be found at
28 http://www.opengis.net/def/uom/OGC/1.0/. Strabon endpoint publishes
29 the URIs at http://localhost:8080/endpoint/Capabilities.
31 * Created new module with name 'vocab` and artifactId
32 'strabon-vocabulary` and moved GeoConstants.java there. Other
33 vocabularies have been added as well, such as Simple Features, and
34 GeoSPARQL.
36 * Strabon endpoint now publishes the URIs of the supported extension
37 functions for stSPARQL and GeoSPARQL. One should access them by
38 hitting the link http://localhost:8080/endpoint/Capabilities.
40 * Support for parsing EPSG URIs in geometry literals with datatype
41 geo:wktLiteral.
42 (bug #33: http://bug.strabon.di.uoa.gr/ticket/33)
44 * GeoSPARQL functions sfCrosses, sfOverlaps, ehOverlaps do not use the
45 ST_Relate PostGIS function (bug #24: http://bug.strabon.di.uoa.gr/ticket/24)
47 * All Simple Features functions of GeoSPARQL do not use the ST_Relate
48 PostGIS function
50 * Added diffTime function. This function performs the difference
51 between two literals of xsd:time datatype and returns a literal of
52 the xsd:time datatype as well.
54 * Added a testsuite package in default branch. Full tester guide can be found
55 in README. Among other, most of GeoSPARQL compliance tests
56 (https://portal.opengeospatial.org/files/?artifact_id=47664, pg. 53) have been
57 implemented.

61 * Version 3.2.8 released.
63 * Added support for handling (storing/querying) GeoSPARQL datatypes.
64 (bug #31: http://bug.strabon.di.uoa.gr/ticket/31)
66 * Fixed a bug in StoreOp that wouldn't close the connection, neither
67 rollback the transaction upon an exception. This had as a side effect
68 the abnormal termination of StoreOp (through for example the use of
69 Ctrl-C signal) which was leaving the database locked.
71 * Fixed bug where spatial aggregates (e.g., union) didn't work as
72 expected when the query didn't contain a `GROUP BY' clause.
73 (bug #22: http://bug.strabon.di.uoa.gr/ticket/22)
75 * Updated GeoSPARQL namespaces and fixed function names to comply with
76 the GeoSPARQL specification.
77 (bug #25: http://bug.strabon.di.uoa.gr/ticket/25)
79 Wed Jan 09 18:06:41 2013 Pyravlos Team
81 * Version 3.2.7 released.
83 * Add an extension function
84 <http://strdf.di.uoa.gr/extensions/ontology#diffDateTime> for computing the
85 span (in milliseconds) between two timestamps.
87 * Added an <endpoint-exec> module. This module builds an executable jar file
88 with an embedded Apache Tomcat 7. To create and run the executable jar just
89 type:
90 $ mvn clean package
91 $ java -jar endpoint-exec/target/strabon-endpoint-executable-*.jar
93 * Modified strabon script and postgis/monetdb.StoreOP class to get an
94 option for storing a RDF file in a named graph. Moreover, the RDF
95 format of the input RDF file now is given as an option (still, if it
96 is missing, it is assumed that the input is in N-TRIPLES format). The
97 option for the format is -f and the option for the named graph is -g
98 (takes a URI as an argument).
100 * Modified the names of the stSPARQL extension functions that
101 utilize the minimum bounding boxes of the involved geometries.
103 Tue Dec 11 19:33:45 2012 Pyravlos Team
105 * Version 3.2.6 released.
107 * Modified the names of the stSPARQL extension functions to comply
108 with the OGC Simple Features Access standard.
110 Tue Dec 11 00:11:43 2012 Pyravlos Team
112 * Version 3.2.5 released.
114 * Added support for querying temporal information. This functionality
115 may be found in the `temporals' branch.
117 The datatypes <http://strdf.di.uoa.gr/ontology#period> and
118 <http://www.w3.org/2001/XMLSchema#dateTime> are used to
119 represent periods and instants respectively.
121 The valid time time of triples is represented using quadtruples,
122 with the valid time annotation(instant or period) being the
123 fourth element of the quad. In the same way, temporal triple
124 patterns are used in queries to retrieve the valid time of
125 triples.
127 Some functions have been renamed (their URIs have changed) to
128 follow the names of the respective relations of Allen's
129 interval algebra and other functions have been added.
131 The following temporal functions are supported:
132 during, periodOverlaps, equalsPeriod, nequalsPeriod, adjacent,
133 before, after, overleft, overright, meets, starts, finishes,
134 period_intersect, period_union, preceding_period, and
135 succeeding_period.
137 * Changed behaviour of Strabon and Strabon Endpoint for connecting to
138 a spatially-enabled database. Only one instance of Strabon is allowed
139 at a time.
141 * Implemented a Java client for Strabon Endpoint. The client should be
142 used only with endpoint versions >=3.2.5. The implementation may be
143 found int the `endpoint-client' submodule of maven. Currently, only
144 querying of Strabon Endpoints is supported.
146 * Added support for requesting the capabilities of Strabon Endpoint
147 (fixes Bug #20 <http://bug.strabon.di.uoa.gr/ticket/20>). See
148 changesets f840796400bf and ?<TBC>? for specific details and how you
149 can determine the capabilities of older endpoints (versions <= 3.2.4).
151 * Updated KML writer to include the projected variables of an stSPARQL
152 query in "ExtendedData" and "Data" tags. This is the proper way to
153 do it if we need to convert a KML to a ESRI shapefile and also include
154 such information as attributes for a feature. See related pages from
155 KML specification:
156 <https://developers.google.com/kml/documentation/kmlreference#extendeddata>
157 <https://developers.google.com/kml/documentation/extendeddata>
159 * Added user authentication for storing RDF data through Strabon
160 Endpoint. The credentials are specified in
161 WEB-INF/credentials.properties file.
163 * Strabon Endpoints now limits the number of the results to a maximum
164 one. The maximum number is specified in the beans.xml file. This
165 corresponds to parameter "maxLimit". The endpoint script has also been
166 updated correspondingly; the limit can be given using the option "-l".
167 One can disable limiting of query results, by setting the "maxLimit"
168 parameter to 0. Addresses Bug #6
169 (<http://bug.strabon.di.uoa.gr/ticket/6>).
171 * Added "Known Issues" section to README.
173 * Added -m (more memory) and -M (much more memory) options in strabon
174 script for out-of-memory exceptions.
176 * Fixed Bug #10 (<http://bug.strabon.di.uoa.gr/ticket/10>). Now
177 KMLWriter handles more geometric types (other than polygons). See
178 changeset 9a3bfee64a39.
180 * Menu and navigation in Strabon Endpoint has changed to use jquery.
181 The menu is now populated using the queries placed inside the beans.xml.
183 * Added BrowseBean and browse.jsp for browsing the RDF data using the
184 Strabon Endpoint.
