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 * GeoSPARQL functions sfCrosses, sfOverlaps, ehOverlaps do not use the
57 ST_Relate PostGIS function (bug #24: http://bug.strabon.di.uoa.gr/ticket/24)
59 * All Simple Features functions of GeoSPARQL do not use the ST_Relate
60 PostGIS function
62 * Added diffTime function. This function performs the difference
63 between two literals of xsd:time datatype and returns a literal of
64 the xsd:time datatype as well.
66 * Added a testsuite package in default branch. Full tester guide can be found
67 in README. Among other, most of GeoSPARQL compliance tests
68 (https://portal.opengeospatial.org/files/?artifact_id=47664, pg. 53) have been
69 implemented.
71 * Changed the definition and implementation of strdf:distance function, by
72 adopting the definition of GeoSPARQL.
73 (bug #23: http://bug.strabon.di.uoa.gr/ticket/23)
75 * Changed the definition and implementation of strdf:buffer function, by
76 adopting the definition of GeoSPARQL.
77 (bug #35: http://bug.strabon.di.uoa.gr/ticket/35)
79 * Added geof:distance and geof:buffer functions, which have the same definition
80 with strdf:distance and strdf:buffer respectively.
82 * Added a download button when performing describe and construct queries at the
83 endpoint.
84 (bug #38: http://bug.strabon.di.uoa.gr/ticket/38)
86 * Fixed a bug, where XMLWriter and TSVWriter did not return geometries with the
87 SRID.
88 (bug #47: http://bug.strabon.di.uoa.gr/ticket/47)
90 * Fixed a bug where the GeoSPARQL construct functions did not return the datatype
91 geo:wktLiteral datatype but strdf:WKT.
93 Tue Mar 26 13:28:26 2013 Pyravlos Team
95 * Version 3.2.8 released.
97 * Added support for handling (storing/querying) GeoSPARQL datatypes.
98 (bug #31: http://bug.strabon.di.uoa.gr/ticket/31)
100 * Fixed a bug in StoreOp that wouldn't close the connection, neither
101 rollback the transaction upon an exception. This had as a side effect
102 the abnormal termination of StoreOp (through for example the use of
103 Ctrl-C signal) which was leaving the database locked.
105 * Fixed bug where spatial aggregates (e.g., union) didn't work as
106 expected when the query didn't contain a `GROUP BY' clause.
107 (bug #22: http://bug.strabon.di.uoa.gr/ticket/22)
109 * Updated GeoSPARQL namespaces and fixed function names to comply with
110 the GeoSPARQL specification.
111 (bug #25: http://bug.strabon.di.uoa.gr/ticket/25)
113 Wed Jan 09 18:06:41 2013 Pyravlos Team
115 * Version 3.2.7 released.
117 * Add an extension function
118 <http://strdf.di.uoa.gr/extensions/ontology#diffDateTime> for computing the
119 span (in milliseconds) between two timestamps.
121 * Added an <endpoint-exec> module. This module builds an executable jar file
122 with an embedded Apache Tomcat 7. To create and run the executable jar just
123 type:
124 $ mvn clean package
125 $ java -jar endpoint-exec/target/strabon-endpoint-executable-*.jar
127 * Modified strabon script and postgis/monetdb.StoreOP class to get an
128 option for storing a RDF file in a named graph. Moreover, the RDF
129 format of the input RDF file now is given as an option (still, if it
130 is missing, it is assumed that the input is in N-TRIPLES format). The
131 option for the format is -f and the option for the named graph is -g
132 (takes a URI as an argument).
134 * Modified the names of the stSPARQL extension functions that
135 utilize the minimum bounding boxes of the involved geometries.
137 Tue Dec 11 19:33:45 2012 Pyravlos Team
139 * Version 3.2.6 released.
141 * Modified the names of the stSPARQL extension functions to comply
142 with the OGC Simple Features Access standard.
144 Tue Dec 11 00:11:43 2012 Pyravlos Team
146 * Version 3.2.5 released.
148 * Added support for querying temporal information. This functionality
149 may be found in the `temporals' branch.
151 The datatypes <http://strdf.di.uoa.gr/ontology#period> and
152 <http://www.w3.org/2001/XMLSchema#dateTime> are used to
153 represent periods and instants respectively.
155 The valid time time of triples is represented using quadtruples,
156 with the valid time annotation(instant or period) being the
157 fourth element of the quad. In the same way, temporal triple
158 patterns are used in queries to retrieve the valid time of
159 triples.
161 Some functions have been renamed (their URIs have changed) to
162 follow the names of the respective relations of Allen's
163 interval algebra and other functions have been added.
165 The following temporal functions are supported:
166 during, periodOverlaps, equalsPeriod, nequalsPeriod, adjacent,
167 before, after, overleft, overright, meets, starts, finishes,
168 period_intersect, period_union, preceding_period, and
169 succeeding_period.
171 * Changed behaviour of Strabon and Strabon Endpoint for connecting to
172 a spatially-enabled database. Only one instance of Strabon is allowed
173 at a time.
175 * Implemented a Java client for Strabon Endpoint. The client should be
176 used only with endpoint versions >=3.2.5. The implementation may be
177 found int the `endpoint-client' submodule of maven. Currently, only
178 querying of Strabon Endpoints is supported.
180 * Added support for requesting the capabilities of Strabon Endpoint
181 (fixes Bug #20 <http://bug.strabon.di.uoa.gr/ticket/20>). See
182 changesets f840796400bf and ?<TBC>? for specific details and how you
183 can determine the capabilities of older endpoints (versions <= 3.2.4).
185 * Updated KML writer to include the projected variables of an stSPARQL
186 query in "ExtendedData" and "Data" tags. This is the proper way to
187 do it if we need to convert a KML to a ESRI shapefile and also include
188 such information as attributes for a feature. See related pages from
189 KML specification:
190 <https://developers.google.com/kml/documentation/kmlreference#extendeddata>
191 <https://developers.google.com/kml/documentation/extendeddata>
193 * Added user authentication for storing RDF data through Strabon
194 Endpoint. The credentials are specified in
195 WEB-INF/credentials.properties file.
197 * Strabon Endpoints now limits the number of the results to a maximum
198 one. The maximum number is specified in the beans.xml file. This
199 corresponds to parameter "maxLimit". The endpoint script has also been
200 updated correspondingly; the limit can be given using the option "-l".
201 One can disable limiting of query results, by setting the "maxLimit"
202 parameter to 0. Addresses Bug #6
203 (<http://bug.strabon.di.uoa.gr/ticket/6>).
205 * Added "Known Issues" section to README.
207 * Added -m (more memory) and -M (much more memory) options in strabon
208 script for out-of-memory exceptions.
210 * Fixed Bug #10 (<http://bug.strabon.di.uoa.gr/ticket/10>). Now
211 KMLWriter handles more geometric types (other than polygons). See
212 changeset 9a3bfee64a39.
214 * Menu and navigation in Strabon Endpoint has changed to use jquery.
215 The menu is now populated using the queries placed inside the beans.xml.
217 * Added BrowseBean and browse.jsp for browsing the RDF data using the
218 Strabon Endpoint.
