3 * Version 3.2.9 released.
5 * Added support for the following google chart types: PieChart,
6 AreaChart and ColumnChart to strabon endpoint.
8 * Added Timemap as new results format in Strabon endpoint. This
9 option displays results in a map and a timeline on the same time,
10 using the Timemap js library (http://code.google.com/p/timemap/).
11 The KMLWriter has been extended for that purpose, by transforming
12 dateTime values that are included in the result set into the respective
13 TimeStamp KML primitive (https://developers.google.com/kml/documentation/time).
14 In the "temporals" branch, the values of the strdf:period datatype
15 are converted into the respective KML TimeSpan primitive.
17 * Added extension function <http://postgis.net/ST_Centroid> which is
18 mapped to the ST_Centroid(geometry) extension function of PostGIS.
19 See also: <http://postgis.org/docs/ST_Centroid.html>.
21 * Added extension function <http://postgis.net/ST_MakeLine> which is
22 mapped to the ST_MakeLine(geometry, geometry) extension function of
23 PostGIS. See also: <http://postgis.org/docs/ST_MakeLine.html>.
25 * Added PostGIS vocabulary class.
27 * Added support of all SPARQL result types provided by Sesame (json,
28 xml, csv, tsv, binary). To get the respective writer, just prepend the
29 string "SPARQL/", e.g., "SPARQL/JSON". This is to ensure that we
30 support all SPARQL result formats of the SPARQL Protocol.
32 * Fixed a bug where a non-implemented extension function would make
33 Strabon throw a NULL pointer exception. Now we get away with it
34 through a warning.
36 * Strabon endpoint now publishes the URIs of the supported units of
37 measure for use in strdf:distance and geof:distance functions of
38 stSPARQL and GeoSPARQL, respectively. The URIs are those defined by
39 OGC Units of Measure 1.0 specification which may be found at
40 http://www.opengis.net/def/uom/OGC/1.0/. Strabon endpoint publishes
41 the URIs at http://localhost:8080/endpoint/Capabilities.
43 * Created new module with name 'vocab` and artifactId
44 'strabon-vocabulary` and moved GeoConstants.java there. Other
45 vocabularies have been added as well, such as Simple Features, and
46 GeoSPARQL.
48 * Strabon endpoint now publishes the URIs of the supported extension
49 functions for stSPARQL and GeoSPARQL. One should access them by
50 hitting the link http://localhost:8080/endpoint/Capabilities.
52 * Support for parsing EPSG URIs in geometry literals with datatype
53 geo:wktLiteral.
54 (bug #33: http://bug.strabon.di.uoa.gr/ticket/33)
56 * Endpoint Client now supports querying of Virtuoso and Parliament endpoints.
58 * Endpoint Client now supports store and update operations, but only
59 for Strabon Endpoints.
61 * GeoSPARQL functions sfCrosses, sfOverlaps, ehOverlaps do not use the
62 ST_Relate PostGIS function (bug #24: http://bug.strabon.di.uoa.gr/ticket/24)
64 * All Simple Features functions of GeoSPARQL do not use the ST_Relate
65 PostGIS function
67 * Added diffTime function. This function performs the difference
68 between two literals of xsd:time datatype and returns a literal of
69 the xsd:time datatype as well.
71 * Added a testsuite package in default branch. Full tester guide can be found
72 in README. Among other, most of GeoSPARQL compliance tests
73 (https://portal.opengeospatial.org/files/?artifact_id=47664, pg. 53) have been
74 implemented.
76 * Changed the definition and implementation of strdf:distance function, by
77 adopting the definition of GeoSPARQL.
78 (bug #23: http://bug.strabon.di.uoa.gr/ticket/23)
80 * Changed the definition and implementation of strdf:buffer function, by
81 adopting the definition of GeoSPARQL.
82 (bug #35: http://bug.strabon.di.uoa.gr/ticket/35)
84 * Added geof:distance and geof:buffer functions, which have the same definition
85 with strdf:distance and strdf:buffer respectively.
86 (bug #32: http://bug.strabon.di.uoa.gr/ticket/32)
88 * Added a download button when performing describe and construct queries at the
89 endpoint.
90 (bug #38: http://bug.strabon.di.uoa.gr/ticket/38)
92 * Fixed a bug, where XMLWriter and TSVWriter did not return geometries with the
93 SRID.
94 (bug #47: http://bug.strabon.di.uoa.gr/ticket/47)
96 * Fixed a bug where the GeoSPARQL construct functions did not return the datatype
97 geo:wktLiteral datatype but strdf:WKT.
99 Tue Mar 26 13:28:26 2013 Pyravlos Team
101 * Version 3.2.8 released.
103 * Added support for handling (storing/querying) GeoSPARQL datatypes.
104 (bug #31: http://bug.strabon.di.uoa.gr/ticket/31)
106 * Fixed a bug in StoreOp that wouldn't close the connection, neither
107 rollback the transaction upon an exception. This had as a side effect
108 the abnormal termination of StoreOp (through for example the use of
109 Ctrl-C signal) which was leaving the database locked.
111 * Fixed bug where spatial aggregates (e.g., union) didn't work as
112 expected when the query didn't contain a `GROUP BY' clause.
113 (bug #22: http://bug.strabon.di.uoa.gr/ticket/22)
115 * Updated GeoSPARQL namespaces and fixed function names to comply with
116 the GeoSPARQL specification.
117 (bug #25: http://bug.strabon.di.uoa.gr/ticket/25)
119 Wed Jan 09 18:06:41 2013 Pyravlos Team
121 * Version 3.2.7 released.
123 * Add an extension function
124 <http://strdf.di.uoa.gr/extensions/ontology#diffDateTime> for computing the
125 span (in milliseconds) between two timestamps.
127 * Added an <endpoint-exec> module. This module builds an executable jar file
128 with an embedded Apache Tomcat 7. To create and run the executable jar just
129 type:
130 $ mvn clean package
131 $ java -jar endpoint-exec/target/strabon-endpoint-executable-*.jar
133 * Modified strabon script and postgis/monetdb.StoreOP class to get an
134 option for storing a RDF file in a named graph. Moreover, the RDF
135 format of the input RDF file now is given as an option (still, if it
136 is missing, it is assumed that the input is in N-TRIPLES format). The
137 option for the format is -f and the option for the named graph is -g
138 (takes a URI as an argument).
140 * Modified the names of the stSPARQL extension functions that
141 utilize the minimum bounding boxes of the involved geometries.
143 Tue Dec 11 19:33:45 2012 Pyravlos Team
145 * Version 3.2.6 released.
147 * Modified the names of the stSPARQL extension functions to comply
148 with the OGC Simple Features Access standard.
150 Tue Dec 11 00:11:43 2012 Pyravlos Team
152 * Version 3.2.5 released.
154 * Added support for querying temporal information. This functionality
155 may be found in the `temporals' branch.
157 The datatypes <http://strdf.di.uoa.gr/ontology#period> and
158 <http://www.w3.org/2001/XMLSchema#dateTime> are used to
159 represent periods and instants respectively.
161 The valid time time of triples is represented using quadtruples,
162 with the valid time annotation(instant or period) being the
163 fourth element of the quad. In the same way, temporal triple
164 patterns are used in queries to retrieve the valid time of
165 triples.
167 Some functions have been renamed (their URIs have changed) to
168 follow the names of the respective relations of Allen's
169 interval algebra and other functions have been added.
171 The following temporal functions are supported:
172 during, periodOverlaps, equalsPeriod, nequalsPeriod, adjacent,
173 before, after, overleft, overright, meets, starts, finishes,
174 period_intersect, period_union, preceding_period, and
175 succeeding_period.
177 * Changed behaviour of Strabon and Strabon Endpoint for connecting to
178 a spatially-enabled database. Only one instance of Strabon is allowed
179 at a time.
181 * Implemented a Java client for Strabon Endpoint. The client should be
182 used only with endpoint versions >=3.2.5. The implementation may be
183 found int the `endpoint-client' submodule of maven. Currently, only
184 querying of Strabon Endpoints is supported.
186 * Added support for requesting the capabilities of Strabon Endpoint
187 (fixes Bug #20 <http://bug.strabon.di.uoa.gr/ticket/20>). See
188 changesets f840796400bf and ?<TBC>? for specific details and how you
189 can determine the capabilities of older endpoints (versions <= 3.2.4).
191 * Updated KML writer to include the projected variables of an stSPARQL
192 query in "ExtendedData" and "Data" tags. This is the proper way to
193 do it if we need to convert a KML to a ESRI shapefile and also include
194 such information as attributes for a feature. See related pages from
195 KML specification:
196 <https://developers.google.com/kml/documentation/kmlreference#extendeddata>
197 <https://developers.google.com/kml/documentation/extendeddata>
199 * Added user authentication for storing RDF data through Strabon
200 Endpoint. The credentials are specified in
201 WEB-INF/credentials.properties file.
203 * Strabon Endpoints now limits the number of the results to a maximum
204 one. The maximum number is specified in the beans.xml file. This
205 corresponds to parameter "maxLimit". The endpoint script has also been
206 updated correspondingly; the limit can be given using the option "-l".
207 One can disable limiting of query results, by setting the "maxLimit"
208 parameter to 0. Addresses Bug #6
209 (<http://bug.strabon.di.uoa.gr/ticket/6>).
211 * Added "Known Issues" section to README.
213 * Added -m (more memory) and -M (much more memory) options in strabon
214 script for out-of-memory exceptions.
216 * Fixed Bug #10 (<http://bug.strabon.di.uoa.gr/ticket/10>). Now
217 KMLWriter handles more geometric types (other than polygons). See
218 changeset 9a3bfee64a39.
220 * Menu and navigation in Strabon Endpoint has changed to use jquery.
221 The menu is now populated using the queries placed inside the beans.xml.
223 * Added BrowseBean and browse.jsp for browsing the RDF data using the
224 Strabon Endpoint.
