3 * Version 3.2.9 released.
5 * Added support of all SPARQL result types provided by Sesame (json,
6 xml, csv, tsv, binary). To get the respective writer, just prepend the
7 string "SPARQL/", e.g., "SPARQL/JSON". This is to ensure that we
8 support all SPARQL result formats of the SPARQL Protocol.
10 * Fixed a bug where a non-implemented extension function would make
11 Strabon throw a NULL pointer exception. Now we get away with it
12 through a warning.
14 * Strabon endpoint now publishes the URIs of the supported units of
15 measure for use in strdf:distance and geof:distance functions of
16 stSPARQL and GeoSPARQL, respectively. The URIs are those defined by
17 OGC Units of Measure 1.0 specification which may be found at
18 http://www.opengis.net/def/uom/OGC/1.0/. Strabon endpoint publishes
19 the URIs at http://localhost:8080/endpoint/Capabilities.
21 * Created new module with name 'vocab` and artifactId
22 'strabon-vocabulary` and moved GeoConstants.java there. Other
23 vocabularies have been added as well, such as Simple Features, and
24 GeoSPARQL.
26 * Strabon endpoint now publishes the URIs of the supported extension
27 functions for stSPARQL and GeoSPARQL. One should access them by
28 hitting the link http://localhost:8080/endpoint/Capabilities.
30 * Support for parsing EPSG URIs in geometry literals with datatype
31 geo:wktLiteral.
32 (bug #33: http://bug.strabon.di.uoa.gr/ticket/33)
34 Tue Mar 26 13:28:26 2013 Pyravlos Team
36 * Version 3.2.8 released.
38 * Added support for handling (storing/querying) GeoSPARQL datatypes.
39 (bug #31: http://bug.strabon.di.uoa.gr/ticket/31)
41 * Fixed a bug in StoreOp that wouldn't close the connection, neither
42 rollback the transaction upon an exception. This had as a side effect
43 the abnormal termination of StoreOp (through for example the use of
44 Ctrl-C signal) which was leaving the database locked.
46 * Fixed bug where spatial aggregates (e.g., union) didn't work as
47 expected when the query didn't contain a `GROUP BY' clause.
48 (bug #22: http://bug.strabon.di.uoa.gr/ticket/22)
50 * Updated GeoSPARQL namespaces and fixed function names to comply with
51 the GeoSPARQL specification.
52 (bug #25: http://bug.strabon.di.uoa.gr/ticket/25)
54 Wed Jan 09 18:06:41 2013 Pyravlos Team
56 * Version 3.2.7 released.
58 * Add an extension function
59 <http://strdf.di.uoa.gr/extensions/ontology#diffDateTime> for computing the
60 span (in milliseconds) between two timestamps.
62 * Added an <endpoint-exec> module. This module builds an executable jar file
63 with an embedded Apache Tomcat 7. To create and run the executable jar just
64 type:
65 $ mvn clean package
66 $ java -jar endpoint-exec/target/strabon-endpoint-executable-*.jar
68 * Modified strabon script and postgis/monetdb.StoreOP class to get an
69 option for storing a RDF file in a named graph. Moreover, the RDF
70 format of the input RDF file now is given as an option (still, if it
71 is missing, it is assumed that the input is in N-TRIPLES format). The
72 option for the format is -f and the option for the named graph is -g
73 (takes a URI as an argument).
75 * Modified the names of the stSPARQL extension functions that
76 utilize the minimum bounding boxes of the involved geometries.
78 Tue Dec 11 19:33:45 2012 Pyravlos Team
80 * Version 3.2.6 released.
82 * Modified the names of the stSPARQL extension functions to comply
83 with the OGC Simple Features Access standard.
85 Tue Dec 11 00:11:43 2012 Pyravlos Team
87 * Version 3.2.5 released.
89 * Added support for querying temporal information. This functionality
90 may be found in the `temporals' branch.
92 The datatypes <http://strdf.di.uoa.gr/ontology#period> and
93 <http://www.w3.org/2001/XMLSchema#dateTime> are used to
94 represent periods and instants respectively.
96 The valid time time of triples is represented using quadtruples,
97 with the valid time annotation(instant or period) being the
98 fourth element of the quad. In the same way, temporal triple
99 patterns are used in queries to retrieve the valid time of
100 triples.
102 Some functions have been renamed (their URIs have changed) to
103 follow the names of the respective relations of Allen's
104 interval algebra and other functions have been added.
106 The following temporal functions are supported:
107 during, periodOverlaps, equalsPeriod, nequalsPeriod, adjacent,
108 before, after, overleft, overright, meets, starts, finishes,
109 period_intersect, period_union, preceding_period, and
110 succeeding_period.
112 * Changed behaviour of Strabon and Strabon Endpoint for connecting to
113 a spatially-enabled database. Only one instance of Strabon is allowed
114 at a time.
116 * Implemented a Java client for Strabon Endpoint. The client should be
117 used only with endpoint versions >=3.2.5. The implementation may be
118 found int the `endpoint-client' submodule of maven. Currently, only
119 querying of Strabon Endpoints is supported.
121 * Added support for requesting the capabilities of Strabon Endpoint
122 (fixes Bug #20 <http://bug.strabon.di.uoa.gr/ticket/20>). See
123 changesets f840796400bf and ?<TBC>? for specific details and how you
124 can determine the capabilities of older endpoints (versions <= 3.2.4).
126 * Updated KML writer to include the projected variables of an stSPARQL
127 query in "ExtendedData" and "Data" tags. This is the proper way to
128 do it if we need to convert a KML to a ESRI shapefile and also include
129 such information as attributes for a feature. See related pages from
130 KML specification:
131 <https://developers.google.com/kml/documentation/kmlreference#extendeddata>
132 <https://developers.google.com/kml/documentation/extendeddata>
134 * Added user authentication for storing RDF data through Strabon
135 Endpoint. The credentials are specified in
136 WEB-INF/credentials.properties file.
138 * Strabon Endpoints now limits the number of the results to a maximum
139 one. The maximum number is specified in the beans.xml file. This
140 corresponds to parameter "maxLimit". The endpoint script has also been
141 updated correspondingly; the limit can be given using the option "-l".
142 One can disable limiting of query results, by setting the "maxLimit"
143 parameter to 0. Addresses Bug #6
144 (<http://bug.strabon.di.uoa.gr/ticket/6>).
146 * Added "Known Issues" section to README.
148 * Added -m (more memory) and -M (much more memory) options in strabon
149 script for out-of-memory exceptions.
151 * Fixed Bug #10 (<http://bug.strabon.di.uoa.gr/ticket/10>). Now
152 KMLWriter handles more geometric types (other than polygons). See
153 changeset 9a3bfee64a39.
155 * Menu and navigation in Strabon Endpoint has changed to use jquery.
156 The menu is now populated using the queries placed inside the beans.xml.
158 * Added BrowseBean and browse.jsp for browsing the RDF data using the
159 Strabon Endpoint.
