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 'vocab` and artifactId
17 'strabon-vocabulary` and moved there. Other
18 vocabularies have been added as well, such as Simple Features, and
21 * Strabon endpoint now publishes the URIs of the supported extension
22 functions for stSPARQL and GeoSPARQL. One should access them by
23 hitting the link http://localhost:8080/endpoint/Capabilities.
25 * Support for parsing EPSG URIs in geometry literals with datatype
26 geo:wktLiteral.
27 (bug #33:
29 Tue Mar 26 13:28:26 2013 Pyravlos Team
31 * Version 3.2.8 released.
33 * Added support for handling (storing/querying) GeoSPARQL datatypes.
34 (bug #31:
36 * Fixed a bug in StoreOp that wouldn't close the connection, neither
37 rollback the transaction upon an exception. This had as a side effect
38 the abnormal termination of StoreOp (through for example the use of
39 Ctrl-C signal) which was leaving the database locked.
41 * Fixed bug where spatial aggregates (e.g., union) didn't work as
42 expected when the query didn't contain a `GROUP BY' clause.
43 (bug #22:
45 * Updated GeoSPARQL namespaces and fixed function names to comply with
46 the GeoSPARQL specification.
47 (bug #25:
49 Wed Jan 09 18:06:41 2013 Pyravlos Team
51 * Version 3.2.7 released.
53 * Add an extension function
54 <> for computing the
55 span (in milliseconds) between two timestamps.
57 * Added an <endpoint-exec> module. This module builds an executable jar file
58 with an embedded Apache Tomcat 7. To create and run the executable jar just
59 type:
60 $ mvn clean package
61 $ java -jar endpoint-exec/target/strabon-endpoint-executable-*.jar
63 * Modified strabon script and postgis/monetdb.StoreOP class to get an
64 option for storing a RDF file in a named graph. Moreover, the RDF
65 format of the input RDF file now is given as an option (still, if it
66 is missing, it is assumed that the input is in N-TRIPLES format). The
67 option for the format is -f and the option for the named graph is -g
68 (takes a URI as an argument).
70 * Modified the names of the stSPARQL extension functions that
71 utilize the minimum bounding boxes of the involved geometries.
73 Tue Dec 11 19:33:45 2012 Pyravlos Team
75 * Version 3.2.6 released.
77 * Modified the names of the stSPARQL extension functions to comply
78 with the OGC Simple Features Access standard.
80 Tue Dec 11 00:11:43 2012 Pyravlos Team
82 * Version 3.2.5 released.
84 * Added support for querying temporal information. This functionality
85 may be found in the `temporals' branch.
87 The datatypes <> and
88 <> are used to
89 represent periods and instants respectively.
91 The valid time time of triples is represented using quadtruples,
92 with the valid time annotation(instant or period) being the
93 fourth element of the quad. In the same way, temporal triple
94 patterns are used in queries to retrieve the valid time of
95 triples.
97 Some functions have been renamed (their URIs have changed) to
98 follow the names of the respective relations of Allen's
99 interval algebra and other functions have been added.
101 The following temporal functions are supported:
102 during, periodOverlaps, equalsPeriod, nequalsPeriod, adjacent,
103 before, after, overleft, overright, meets, starts, finishes,
104 period_intersect, period_union, preceding_period, and
105 succeeding_period.
107 * Changed behaviour of Strabon and Strabon Endpoint for connecting to
108 a spatially-enabled database. Only one instance of Strabon is allowed
109 at a time.
111 * Implemented a Java client for Strabon Endpoint. The client should be
112 used only with endpoint versions >=3.2.5. The implementation may be
113 found int the `endpoint-client' submodule of maven. Currently, only
114 querying of Strabon Endpoints is supported.
116 * Added support for requesting the capabilities of Strabon Endpoint
117 (fixes Bug #20 <>). See
118 changesets f840796400bf and ?<TBC>? for specific details and how you
119 can determine the capabilities of older endpoints (versions <= 3.2.4).
121 * Updated KML writer to include the projected variables of an stSPARQL
122 query in "ExtendedData" and "Data" tags. This is the proper way to
123 do it if we need to convert a KML to a ESRI shapefile and also include
124 such information as attributes for a feature. See related pages from
125 KML specification:
126 <>
127 <>
129 * Added user authentication for storing RDF data through Strabon
130 Endpoint. The credentials are specified in
131 WEB-INF/ file.
133 * Strabon Endpoints now limits the number of the results to a maximum
134 one. The maximum number is specified in the beans.xml file. This
135 corresponds to parameter "maxLimit". The endpoint script has also been
136 updated correspondingly; the limit can be given using the option "-l".
137 One can disable limiting of query results, by setting the "maxLimit"
138 parameter to 0. Addresses Bug #6
139 (<>).
141 * Added "Known Issues" section to README.
143 * Added -m (more memory) and -M (much more memory) options in strabon
144 script for out-of-memory exceptions.
146 * Fixed Bug #10 (<>). Now
147 KMLWriter handles more geometric types (other than polygons). See
148 changeset 9a3bfee64a39.
150 * Menu and navigation in Strabon Endpoint has changed to use jquery.
151 The menu is now populated using the queries placed inside the beans.xml.
153 * Added BrowseBean and browse.jsp for browsing the RDF data using the
154 Strabon Endpoint.
