3 * Version 3.2.9 released.
5 * Fixed a bug where a non-implemented extension function would make
6 Strabon throw a NULL pointer exception. Now we get away with it
7 through a warning.
9 * Strabon endpoint now publishes the URIs of the supported units of
10 measure for use in strdf:distance and geof:distance functions of
11 stSPARQL and GeoSPARQL, respectively. The URIs are those defined by
12 OGC Units of Measure 1.0 specification which may be found at
13 Strabon endpoint publishes
14 the URIs at http://localhost:8080/endpoint/Capabilities.
16 * Created new module with name 'constants` and artifactId
17 'spatial-temporal-constants` and moved there.
19 * Strabon endpoint now publishes the URIs of the supported extension
20 functions for stSPARQL and GeoSPARQL. One should access them by
21 hitting the link http://localhost:8080/endpoint/Capabilities.
23 * Support for parsing EPSG URIs in geometry literals with datatype
24 geo:wktLiteral.

27 Tue Mar 26 13:28:26 2013 Pyravlos Team
29 * Version 3.2.8 released.
31 * Added support for handling (storing/querying) GeoSPARQL datatypes.
32 (bug #31:
34 * Fixed a bug in StoreOp that wouldn't close the connection, neither
35 rollback the transaction upon an exception. This had as a side effect
36 the abnormal termination of StoreOp (through for example the use of
37 Ctrl-C signal) which was leaving the database locked.
39 * Fixed bug where spatial aggregates (e.g., union) didn't work as
40 expected when the query didn't contain a `GROUP BY' clause.
41 (bug #22:
43 * Updated GeoSPARQL namespaces and fixed function names to comply with
44 the GeoSPARQL specification.

47 Wed Jan 09 18:06:41 2013 Pyravlos Team
49 * Version 3.2.7 released.
51 * Add an extension function
52 <> for computing the
53 span (in milliseconds) between two timestamps.
55 * Added an <endpoint-exec> module. This module builds an executable jar file
56 with an embedded Apache Tomcat 7. To create and run the executable jar just
57 type:
58 $ mvn clean package
59 $ java -jar endpoint-exec/target/strabon-endpoint-executable-*.jar
61 * Modified strabon script and postgis/monetdb.StoreOP class to get an
62 option for storing a RDF file in a named graph. Moreover, the RDF
63 format of the input RDF file now is given as an option (still, if it
64 is missing, it is assumed that the input is in N-TRIPLES format). The
65 option for the format is -f and the option for the named graph is -g
66 (takes a URI as an argument).
68 * Modified the names of the stSPARQL extension functions that
69 utilize the minimum bounding boxes of the involved geometries.
71 Tue Dec 11 19:33:45 2012 Pyravlos Team
73 * Version 3.2.6 released.
75 * Modified the names of the stSPARQL extension functions to comply
76 with the OGC Simple Features Access standard.
78 Tue Dec 11 00:11:43 2012 Pyravlos Team
80 * Version 3.2.5 released.
82 * Added support for querying temporal information. This functionality
83 may be found in the `temporals' branch.
85 The datatypes <> and
86 <> are used to
87 represent periods and instants respectively.
89 The valid time time of triples is represented using quadtruples,
90 with the valid time annotation(instant or period) being the
91 fourth element of the quad. In the same way, temporal triple
92 patterns are used in queries to retrieve the valid time of
93 triples.
95 Some functions have been renamed (their URIs have changed) to
96 follow the names of the respective relations of Allen's
97 interval algebra and other functions have been added.
99 The following temporal functions are supported:
100 during, periodOverlaps, equalsPeriod, nequalsPeriod, adjacent,
101 before, after, overleft, overright, meets, starts, finishes,
102 period_intersect, period_union, preceding_period, and
103 succeeding_period.
105 * Changed behaviour of Strabon and Strabon Endpoint for connecting to
106 a spatially-enabled database. Only one instance of Strabon is allowed
107 at a time.
109 * Implemented a Java client for Strabon Endpoint. The client should be
110 used only with endpoint versions >=3.2.5. The implementation may be
111 found int the `endpoint-client' submodule of maven. Currently, only
112 querying of Strabon Endpoints is supported.
114 * Added support for requesting the capabilities of Strabon Endpoint
115 (fixes Bug #20 <>). See
116 changesets f840796400bf and ?<TBC>? for specific details and how you
117 can determine the capabilities of older endpoints (versions <= 3.2.4).
119 * Updated KML writer to include the projected variables of an stSPARQL
120 query in "ExtendedData" and "Data" tags. This is the proper way to
121 do it if we need to convert a KML to a ESRI shapefile and also include
122 such information as attributes for a feature. See related pages from
123 KML specification:
124 <>
125 <>
127 * Added user authentication for storing RDF data through Strabon
128 Endpoint. The credentials are specified in
129 WEB-INF/ file.
131 * Strabon Endpoints now limits the number of the results to a maximum
132 one. The maximum number is specified in the beans.xml file. This
133 corresponds to parameter "maxLimit". The endpoint script has also been
134 updated correspondingly; the limit can be given using the option "-l".
135 One can disable limiting of query results, by setting the "maxLimit"
136 parameter to 0. Addresses Bug #6
137 (<>).
139 * Added "Known Issues" section to README.
141 * Added -m (more memory) and -M (much more memory) options in strabon
142 script for out-of-memory exceptions.
144 * Fixed Bug #10 (<>). Now
145 KMLWriter handles more geometric types (other than polygons). See
146 changeset 9a3bfee64a39.
148 * Menu and navigation in Strabon Endpoint has changed to use jquery.
149 The menu is now populated using the queries placed inside the beans.xml.
151 * Added BrowseBean and browse.jsp for browsing the RDF data using the
152 Strabon Endpoint.
