1 Day Month Date Hour:Min:Sec Year Pyravlos Team
3 * Version 3.2.8 released.
5 Wed Jan 09 18:06:41 2013 Pyravlos Team
7 * Version 3.2.7 released.
9 * Add an extension function
10 <> for computing the
11 span (in milliseconds) between two timestamps.
13 * Added an <endpoint-exec> module. This module builds an executable jar file
14 with an embedded Apache Tomcat 7. To create and run the executable jar just
15 type:
16 $ mvn clean package
17 $ java -jar endpoint-exec/target/strabon-endpoint-executable-*.jar
19 * Modified strabon script and postgis/monetdb.StoreOP class to get an
20 option for storing a RDF file in a named graph. Moreover, the RDF
21 format of the input RDF file now is given as an option (still, if it
22 is missing, it is assumed that the input is in N-TRIPLES format). The
23 option for the format is -f and the option for the named graph is -g
24 (takes a URI as an argument).
26 * Modified the names of the stSPARQL extension functions that
27 utilize the minimum bounding boxes of the involved geometries.
29 Tue Dec 11 19:33:45 2012 Pyravlos Team
31 * Version 3.2.6 released.
33 * Modified the names of the stSPARQL extension functions to comply
34 with the OGC Simple Features Access standard.
36 Tue Dec 11 00:11:43 2012 Pyravlos Team
38 * Version 3.2.5 released.
40 * Added support for querying temporal information. This functionality
41 may be found in the `temporals' branch.
43 The datatypes <> and
44 <> are used to
45 represent periods and instants respectively.
47 The valid time time of triples is represented using quadtruples,
48 with the valid time annotation(instant or period) being the
49 fourth element of the quad. In the same way, temporal triple
50 patterns are used in queries to retrieve the valid time of
51 triples.
53 Some functions have been renamed (their URIs have changed) to
54 follow the names of the respective relations of Allen's
55 interval algebra and other functions have been added.
57 The following temporal functions are supported:
58 during, periodOverlaps, equalsPeriod, nequalsPeriod, adjacent,
59 before, after, overleft, overright, meets, starts, finishes,
60 period_intersect, period_union, preceding_period, and
61 succeeding_period.
63 * Changed behaviour of Strabon and Strabon Endpoint for connecting to
64 a spatially-enabled database. Only one instance of Strabon is allowed
65 at a time.
67 * Implemented a Java client for Strabon Endpoint. The client should be
68 used only with endpoint versions >=3.2.5. The implementation may be
69 found int the `endpoint-client' submodule of maven. Currently, only
70 querying of Strabon Endpoints is supported.
72 * Added support for requesting the capabilities of Strabon Endpoint
73 (fixes Bug #20 <>). See
74 changesets f840796400bf and ?<TBC>? for specific details and how you
75 can determine the capabilities of older endpoints (versions <= 3.2.4).
77 * Updated KML writer to include the projected variables of an stSPARQL
78 query in "ExtendedData" and "Data" tags. This is the proper way to
79 do it if we need to convert a KML to a ESRI shapefile and also include
80 such information as attributes for a feature. See related pages from
81 KML specification:
82 <>
83 <>
85 * Added user authentication for storing RDF data through Strabon
86 Endpoint. The credentials are specified in
87 WEB-INF/ file.
89 * Strabon Endpoints now limits the number of the results to a maximum
90 one. The maximum number is specified in the beans.xml file. This
91 corresponds to parameter "maxLimit". The endpoint script has also been
92 updated correspondingly; the limit can be given using the option "-l".
93 One can disable limiting of query results, by setting the "maxLimit"
94 parameter to 0. Addresses Bug #6
95 (<>).
97 * Added "Known Issues" section to README.
99 * Added -m (more memory) and -M (much more memory) options in strabon
100 script for out-of-memory exceptions.
102 * Fixed Bug #10 (<>). Now
103 KMLWriter handles more geometric types (other than polygons). See
104 changeset 9a3bfee64a39.
106 * Menu and navigation in Strabon Endpoint has changed to use jquery.
107 The menu is now populated using the queries placed inside the beans.xml.
109 * Added BrowseBean and browse.jsp for browsing the RDF data using the
110 Strabon Endpoint.
