3 * Version 3.2.9 released.
5 * Added extension function <> which is
6 mapped to the ST_MakeLine(geometry, geometry) extension function of
7 PostGIS. See also: <>.
9 * Added PostGIS vocabulary class.
11 * Added support of all SPARQL result types provided by Sesame (json,
12 xml, csv, tsv, binary). To get the respective writer, just prepend the
13 string "SPARQL/", e.g., "SPARQL/JSON". This is to ensure that we
14 support all SPARQL result formats of the SPARQL Protocol.
16 * Fixed a bug where a non-implemented extension function would make
17 Strabon throw a NULL pointer exception. Now we get away with it
18 through a warning.
20 * Strabon endpoint now publishes the URIs of the supported units of
21 measure for use in strdf:distance and geof:distance functions of
22 stSPARQL and GeoSPARQL, respectively. The URIs are those defined by
23 OGC Units of Measure 1.0 specification which may be found at
24 Strabon endpoint publishes
25 the URIs at http://localhost:8080/endpoint/Capabilities.
27 * Created new module with name 'vocab` and artifactId
28 'strabon-vocabulary` and moved there. Other
29 vocabularies have been added as well, such as Simple Features, and
32 * Strabon endpoint now publishes the URIs of the supported extension
33 functions for stSPARQL and GeoSPARQL. One should access them by
34 hitting the link http://localhost:8080/endpoint/Capabilities.
36 * Support for parsing EPSG URIs in geometry literals with datatype
37 geo:wktLiteral.

42 * Version 3.2.8 released.
44 * Added support for handling (storing/querying) GeoSPARQL datatypes.
45 (bug #31:
47 * Fixed a bug in StoreOp that wouldn't close the connection, neither
48 rollback the transaction upon an exception. This had as a side effect
49 the abnormal termination of StoreOp (through for example the use of
50 Ctrl-C signal) which was leaving the database locked.
52 * Fixed bug where spatial aggregates (e.g., union) didn't work as
53 expected when the query didn't contain a `GROUP BY' clause.
54 (bug #22:
56 * Updated GeoSPARQL namespaces and fixed function names to comply with
57 the GeoSPARQL specification.

60 Wed Jan 09 18:06:41 2013 Pyravlos Team
62 * Version 3.2.7 released.
64 * Add an extension function
65 <> for computing the
66 span (in milliseconds) between two timestamps.
68 * Added an <endpoint-exec> module. This module builds an executable jar file
69 with an embedded Apache Tomcat 7. To create and run the executable jar just
70 type:
71 $ mvn clean package
72 $ java -jar endpoint-exec/target/strabon-endpoint-executable-*.jar
74 * Modified strabon script and postgis/monetdb.StoreOP class to get an
75 option for storing a RDF file in a named graph. Moreover, the RDF
76 format of the input RDF file now is given as an option (still, if it
77 is missing, it is assumed that the input is in N-TRIPLES format). The
78 option for the format is -f and the option for the named graph is -g
79 (takes a URI as an argument).
81 * Modified the names of the stSPARQL extension functions that
82 utilize the minimum bounding boxes of the involved geometries.
84 Tue Dec 11 19:33:45 2012 Pyravlos Team
86 * Version 3.2.6 released.
88 * Modified the names of the stSPARQL extension functions to comply
89 with the OGC Simple Features Access standard.
91 Tue Dec 11 00:11:43 2012 Pyravlos Team
93 * Version 3.2.5 released.
95 * Added support for querying temporal information. This functionality
96 may be found in the `temporals' branch.
98 The datatypes <> and
99 <> are used to
100 represent periods and instants respectively.
102 The valid time time of triples is represented using quadtruples,
103 with the valid time annotation(instant or period) being the
104 fourth element of the quad. In the same way, temporal triple
105 patterns are used in queries to retrieve the valid time of
106 triples.
108 Some functions have been renamed (their URIs have changed) to
109 follow the names of the respective relations of Allen's
110 interval algebra and other functions have been added.
112 The following temporal functions are supported:
113 during, periodOverlaps, equalsPeriod, nequalsPeriod, adjacent,
114 before, after, overleft, overright, meets, starts, finishes,
115 period_intersect, period_union, preceding_period, and
116 succeeding_period.
118 * Changed behaviour of Strabon and Strabon Endpoint for connecting to
119 a spatially-enabled database. Only one instance of Strabon is allowed
120 at a time.
122 * Implemented a Java client for Strabon Endpoint. The client should be
123 used only with endpoint versions >=3.2.5. The implementation may be
124 found int the `endpoint-client' submodule of maven. Currently, only
125 querying of Strabon Endpoints is supported.
127 * Added support for requesting the capabilities of Strabon Endpoint
128 (fixes Bug #20 <>). See
129 changesets f840796400bf and ?<TBC>? for specific details and how you
130 can determine the capabilities of older endpoints (versions <= 3.2.4).
132 * Updated KML writer to include the projected variables of an stSPARQL
133 query in "ExtendedData" and "Data" tags. This is the proper way to
134 do it if we need to convert a KML to a ESRI shapefile and also include
135 such information as attributes for a feature. See related pages from
136 KML specification:
137 <>
138 <>
140 * Added user authentication for storing RDF data through Strabon
141 Endpoint. The credentials are specified in
142 WEB-INF/ file.
144 * Strabon Endpoints now limits the number of the results to a maximum
145 one. The maximum number is specified in the beans.xml file. This
146 corresponds to parameter "maxLimit". The endpoint script has also been
147 updated correspondingly; the limit can be given using the option "-l".
148 One can disable limiting of query results, by setting the "maxLimit"
149 parameter to 0. Addresses Bug #6
150 (<>).
152 * Added "Known Issues" section to README.
154 * Added -m (more memory) and -M (much more memory) options in strabon
155 script for out-of-memory exceptions.
157 * Fixed Bug #10 (<>). Now
158 KMLWriter handles more geometric types (other than polygons). See
159 changeset 9a3bfee64a39.
161 * Menu and navigation in Strabon Endpoint has changed to use jquery.
162 The menu is now populated using the queries placed inside the beans.xml.
164 * Added BrowseBean and browse.jsp for browsing the RDF data using the
165 Strabon Endpoint.
