3 * Version 3.2.9 released.
5 * Added extension function <> which is
6 mapped to the ST_Centroid(geometry) extension function of PostGIS.
7 See also: <>.
9 * Added extension function <> which is
10 mapped to the ST_MakeLine(geometry, geometry) extension function of
11 PostGIS. See also: <>.
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 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 there. Other
33 vocabularies have been added as well, such as Simple Features, and
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:
44 * GeoSPARQL functions sfCrosses, sfOverlaps, ehOverlaps do not use the
45 ST_Relate PostGIS function (bug #24:
47 * All Simple Features functions of GeoSPARQL do not use the ST_Relate
48 PostGIS function
50 Tue Mar 26 13:28:26 2013 Pyravlos Team
52 * Version 3.2.8 released.
54 * Added support for handling (storing/querying) GeoSPARQL datatypes.
55 (bug #31:
57 * Fixed a bug in StoreOp that wouldn't close the connection, neither
58 rollback the transaction upon an exception. This had as a side effect
59 the abnormal termination of StoreOp (through for example the use of
60 Ctrl-C signal) which was leaving the database locked.
62 * Fixed bug where spatial aggregates (e.g., union) didn't work as
63 expected when the query didn't contain a `GROUP BY' clause.
64 (bug #22:
66 * Updated GeoSPARQL namespaces and fixed function names to comply with
67 the GeoSPARQL specification.
68 (bug #25:
70 Wed Jan 09 18:06:41 2013 Pyravlos Team
72 * Version 3.2.7 released.
74 * Add an extension function
75 <> for computing the
76 span (in milliseconds) between two timestamps.
78 * Added an <endpoint-exec> module. This module builds an executable jar file
79 with an embedded Apache Tomcat 7. To create and run the executable jar just
80 type:
81 $ mvn clean package
82 $ java -jar endpoint-exec/target/strabon-endpoint-executable-*.jar
84 * Modified strabon script and postgis/monetdb.StoreOP class to get an
85 option for storing a RDF file in a named graph. Moreover, the RDF
86 format of the input RDF file now is given as an option (still, if it
87 is missing, it is assumed that the input is in N-TRIPLES format). The
88 option for the format is -f and the option for the named graph is -g
89 (takes a URI as an argument).
91 * Modified the names of the stSPARQL extension functions that
92 utilize the minimum bounding boxes of the involved geometries.
94 Tue Dec 11 19:33:45 2012 Pyravlos Team
96 * Version 3.2.6 released.
98 * Modified the names of the stSPARQL extension functions to comply
99 with the OGC Simple Features Access standard.
101 Tue Dec 11 00:11:43 2012 Pyravlos Team
103 * Version 3.2.5 released.
105 * Added support for querying temporal information. This functionality
106 may be found in the `temporals' branch.
108 The datatypes <> and
109 <> are used to
110 represent periods and instants respectively.
112 The valid time time of triples is represented using quadtruples,
113 with the valid time annotation(instant or period) being the
114 fourth element of the quad. In the same way, temporal triple
115 patterns are used in queries to retrieve the valid time of
116 triples.
118 Some functions have been renamed (their URIs have changed) to
119 follow the names of the respective relations of Allen's
120 interval algebra and other functions have been added.
122 The following temporal functions are supported:
123 during, periodOverlaps, equalsPeriod, nequalsPeriod, adjacent,
124 before, after, overleft, overright, meets, starts, finishes,
125 period_intersect, period_union, preceding_period, and
126 succeeding_period.
128 * Changed behaviour of Strabon and Strabon Endpoint for connecting to
129 a spatially-enabled database. Only one instance of Strabon is allowed
130 at a time.
132 * Implemented a Java client for Strabon Endpoint. The client should be
133 used only with endpoint versions >=3.2.5. The implementation may be
134 found int the `endpoint-client' submodule of maven. Currently, only
135 querying of Strabon Endpoints is supported.
137 * Added support for requesting the capabilities of Strabon Endpoint
138 (fixes Bug #20 <>). See
139 changesets f840796400bf and ?<TBC>? for specific details and how you
140 can determine the capabilities of older endpoints (versions <= 3.2.4).
142 * Updated KML writer to include the projected variables of an stSPARQL
143 query in "ExtendedData" and "Data" tags. This is the proper way to
144 do it if we need to convert a KML to a ESRI shapefile and also include
145 such information as attributes for a feature. See related pages from
146 KML specification:
147 <>
148 <>
150 * Added user authentication for storing RDF data through Strabon
151 Endpoint. The credentials are specified in
152 WEB-INF/ file.
154 * Strabon Endpoints now limits the number of the results to a maximum
155 one. The maximum number is specified in the beans.xml file. This
156 corresponds to parameter "maxLimit". The endpoint script has also been
157 updated correspondingly; the limit can be given using the option "-l".
158 One can disable limiting of query results, by setting the "maxLimit"
159 parameter to 0. Addresses Bug #6
160 (<>).
162 * Added "Known Issues" section to README.
164 * Added -m (more memory) and -M (much more memory) options in strabon
165 script for out-of-memory exceptions.
167 * Fixed Bug #10 (<>). Now
168 KMLWriter handles more geometric types (other than polygons). See
169 changeset 9a3bfee64a39.
171 * Menu and navigation in Strabon Endpoint has changed to use jquery.
172 The menu is now populated using the queries placed inside the beans.xml.
174 * Added BrowseBean and browse.jsp for browsing the RDF data using the
175 Strabon Endpoint.
