2
3  * Added support for posing ASK queries.
4  * Added option to store results in file using QueryOp

7
8        * Bug #82 fixed : Added capability to Endpoint for the user to supply
9          and store his unique Google Maps API Key. The context path of the
10          endpoint is not restricted when a Key is provided. Users that do not
11          supply a key can still run the application as before.

14       
15        * Bug #73, modified appendBuffer function to take the srid into
16          consideration even if the argument is a constant (wktLiteral
17          or strdf literal)
18
19        * Update jar references on scripts used by the debian packaging.
20          Previously these references pointed only (incorrectly) to
21          SNAPSHOTs.
22
23        * Updated package names (since repositories cannot include capital
24          letters + runtime and endpoint-exec must have different names
25
26        * Version 3.3.1 released.
27
28        * Bug #58, added script that is invoked my maven to also update the
29          version described in the deb/control file of the runtime and
30          endpoint-exec components.
31
32        * Related to bug #58, but it generally enhances Strabon; The runtime
33          component has also been debianized. Dependencies are added to
34          /usr/share/jdeb/lib/strabon-runtime. ClassPath and strabon script
35          have also been updated accordingly (strabon-cmd)
36
37        * Bug #58: Maven creates the debian package conditionally. Use
38          -Ddebian=true in the mvn package command.
39
40        * Bug #58: Added dependencies - java, postgresql, tomcat. Also, added
41          a strabon-init script that detects the postgis installation path
42          and sets up the template_postgis. Finally the script creates a db
43          called "endpoint" (assuming it does not already exist) that is used
44          for the strabon-endpoint command.
45       
46        * Fixed an issue that returned null SRID when unmarshalling GML geometries if
47          the SRID did not follow one of the supported formats by GML-JTS. To fix that
48          we added a function that handles these cases by reading the userData variable
49          that JTS provides.
50
51        * Fixed a bug that would return no results when a variable that results
52          from a BIND clause appears in the FILTER or in the projection of a
53          query and is inside a spatial function.
54          (bug #78: http://bug.strabon.di.uoa.gr/ticket/78)
55
56        * Fixed the precision of the geometry literals in GeoJSON writer. Now,
57          this defaults to the precision model of JTS (equals to 16). Prior to
58          this it was fixed to 4.
59
60        * Now the GeoJSON writer is aware of the kind of typed literals (e.g.,
61          numeric, boolean, calendar, etc.) and prints the corresponding
62          values according to these types.
63
64        * Fixed a bug that would not return the correct result or would fail
65          when a spatial function involved a constant and a variable.
66          (bug #74: http://bug.strabon.di.uoa.gr/ticket/74)
67
68        * Fixed a bug that would not return the correct spatial datatype of a
69          projected geometry literal stored in the database.
70          (bug #71: http://bug.strabon.di.uoa.gr/ticket/71)
71
72        * Now, geometries expressed in CRS84 and a `geo:wktLiteral' datatype
73          are assigned the correct CRS, i.e., EPSG:4326 with a longitude
74          latitude axis order.
75
76        * Now, we report a parse error when a constant geometry given in a
77          SELECT or HAVING clause is not well-formed according to the WKT
78          specification.
79          (bug #69: http://bug.strabon.di.uoa.gr/ticket/69)
80
81        * Function `geof:convexHull' is now supported in a Having clause.
82
83        * Fixed older implementation of `strdf:distance' that would expect two
84          arguments instead of three when present in a HAVING clause.
85
86        * Fixed a bug that would cause a class cast exception for grounded
87          expressions with function nesting in the SELECT or HAVING clause.
88
89        * Fixed a bug in which `postgis:ST_Centroid' did not work in the SELECT
90          clause with input geometries from the database.
91
92        * Fixed a bug that `geof:getSRID' would return an integer instead of a
93          the URI corrresponding to the CRS that the input geometry was
94          expressed.
95          (bug #32:  http://bug.strabon.di.uoa.gr/ticket/32)
96
97        * Fixed a bug that would raise an exception for queries involving two
98          UNION graph patterns and a projection to a predicate or a URI in
99          general.
100          (bug #53: http://bug.strabon.di.uoa.gr/ticket/53)
101
102Wed Sep 17 20:14:12 2014   Pyravlos Team
103
104        * Version 3.2.10 released.
105
106        * The test suite of Strabon has now reached a mature level. It
107          contains tests for both stSPARQL and GeoSPARQL query languages and
108          most of the compliance tests covered in the specification of
109          GeoSPARQL (well, only those tests for the components that we have
110          chosen to implement).
111
112        * The endpoint now parses Accept headers with multiple values and uses
113          the first mimetype corresponding to a valid stSPARQLQueryResultFormat.
114          (bug #64: http://bug.strabon.di.uoa.gr/ticket/64)
115
116        * The endpoint now registers a handler for SIGTERM signals, so that if
117          it is run from the command-line (endpoint-exec), then the closing of
118          the connection will be ultimately called.
119          (bug #40: http://bug.strabon.di.uoa.gr/ticket/40)
120
121        * Strabon goes debian v1. the endpoint-exec jar is now given in a .deb
122          format. By dpkg-ing it, one can run a stand alone strabon endpoint
123          locally.
124          (bug #45 http://bug.strabon.di.uoa.gr/ticket/58)
125
126        * Fixed a bug in which Strabon hanged when a unary spatial construct
127          had a ternary spatial construct as argument.
128          (bug #45 http://bug.strabon.di.uoa.gr/ticket/45)
129
130        * Fixed a bug according to which spatial functions in ORDER BY were not
131          evaluated at all.
132          (bug #62: http://bug.strabon.di.uoa.gr/ticket/62)
133
134        * Fixed a bug according to which spatial boolean functions appearing
135          in the SELECT clause were raising a NULL pointer exception.
136          (bug #34: http://bug.strabon.di.uoa.gr/ticket/34)
137
138        * Fixed a bug in queries that contain variables that exist inside
139          spatial functions in select and do not exist in the where clause
140          made Strabon throw a NULL pointer exception.
141          (bug #51 https://bug.strabon.di.uoa.gr/ticket/51)
142
143        * Various changes in the interface and behavior of Strabon Endpoint:
144          - Revised the logos and the sample queries.
145          - Results query limit is set to zero (unlimited).
146          - Users can now store RDF data that is present in a file on the
147            client side (the file is uploaded to the server).
148          - Credentials are now required for uploading files or executing
149            UPDATE queries, unless Strabon Endpoint runs locally (localhost).
150          - When viewing the results of queries in HTML, any URI is now an
151            active link to itself. Previously, that URI was being DESCRIBEd
152            and one was being transferred to a page viewing the result of the
153            DESCRIBE query.
154          - The DESCRIBE functionality can now be accessed through the menu bar.
155       
156        * Fixed a bug where strdf:intersection function did not work as an
157          aggregate when used without 'GROUP BY'.
158          (bug #46 https://bug.strabon.di.uoa.gr/ticket/46)
159
160
161Sat Oct 19 23:37:23 2013   Pyravlos Team
162
163        * Version 3.2.9 released.
164
165        * Added support for the following google chart types: PieChart,
166        AreaChart and ColumnChart to strabon endpoint.
167       
168        * Added Timemap as new results format in Strabon endpoint. This
169        option displays results in a map and a timeline on the same time,
170        using the Timemap js library (http://code.google.com/p/timemap/).
171        The KMLWriter has been extended for that purpose, by transforming
172        dateTime values that are included in the result set into the respective
173        TimeStamp KML primitive (https://developers.google.com/kml/documentation/time).
174        In the "temporals" branch, the values of the strdf:period datatype
175        are converted into the respective KML TimeSpan primitive.
176       
177        * Added extension function <http://postgis.net/ST_Centroid> which is
178        mapped to the ST_Centroid(geometry) extension function of PostGIS.
179        See also: <http://postgis.org/docs/ST_Centroid.html>.
180
181        * Added extension function <http://postgis.net/ST_MakeLine> which is
182        mapped to the ST_MakeLine(geometry, geometry) extension function of
183        PostGIS. See also: <http://postgis.org/docs/ST_MakeLine.html>.
184
185        * Added PostGIS vocabulary class.
186
187        * Added support of all SPARQL result types provided by Sesame (json,
188        xml, csv, tsv, binary). To get the respective writer, just prepend the
189        string "SPARQL/", e.g., "SPARQL/JSON". This is to ensure that we
190        support all SPARQL result formats of the SPARQL Protocol.
191
192        * Fixed a bug where a non-implemented extension function would make
193        Strabon throw a NULL pointer exception. Now we get away with it
194        through a warning.
195
196        * Strabon endpoint now publishes the URIs of the supported units of
197        measure for use in strdf:distance and geof:distance functions of
198        stSPARQL and GeoSPARQL, respectively. The URIs are those defined by
199        OGC Units of Measure 1.0 specification which may be found at
200        http://www.opengis.net/def/uom/OGC/1.0/. Strabon endpoint publishes
201        the URIs at http://localhost:8080/endpoint/Capabilities.
202
203        * Created new module with name 'vocab` and artifactId
204        'strabon-vocabulary` and moved GeoConstants.java there. Other
205        vocabularies have been added as well, such as Simple Features, and
206        GeoSPARQL.
207
208        * Strabon endpoint now publishes the URIs of the supported extension
209        functions for stSPARQL and GeoSPARQL. One should access them by
210        hitting the link http://localhost:8080/endpoint/Capabilities.
211
212        * Support for parsing EPSG URIs in geometry literals with datatype
213        geo:wktLiteral.
214        (bug #33: http://bug.strabon.di.uoa.gr/ticket/33)
215
216        * Endpoint Client now supports querying of Virtuoso and Parliament endpoints.
217
218        * Endpoint Client now supports store and update operations, but only
219        for Strabon Endpoints.
220
221        * GeoSPARQL functions sfCrosses, sfOverlaps, ehOverlaps do not use the
222        ST_Relate PostGIS function (bug #24: http://bug.strabon.di.uoa.gr/ticket/24)
223
224        * All Simple Features functions of GeoSPARQL do not use the ST_Relate
225        PostGIS function
226
227        * Added diffTime function. This function performs the difference
228        between two literals of xsd:time datatype and returns a literal of
229        the xsd:time datatype as well.
230       
231        * Added a testsuite package in default branch. Full tester guide can be found
232        in README. Among other, most of GeoSPARQL compliance tests 
233        (https://portal.opengeospatial.org/files/?artifact_id=47664, pg. 53) have been
234        implemented.
235
236        * Changed the definition and implementation of strdf:distance function, by
237        adopting the definition of GeoSPARQL.
238        (bug #23: http://bug.strabon.di.uoa.gr/ticket/23)
239
240        * Changed the definition and implementation of strdf:buffer function, by
241        adopting the definition of GeoSPARQL.
242        (bug #35: http://bug.strabon.di.uoa.gr/ticket/35)
243
244        * Added geof:distance and geof:buffer functions, which have the same definition
245        with strdf:distance and strdf:buffer respectively.
246        (bug #32: http://bug.strabon.di.uoa.gr/ticket/32)
247
248        * Added a download button when performing describe and construct queries at the
249        endpoint.
250        (bug #38: http://bug.strabon.di.uoa.gr/ticket/38)
251
252        * Fixed a bug, where XMLWriter and TSVWriter did not return geometries with the
253        SRID.
254        (bug #47: http://bug.strabon.di.uoa.gr/ticket/47)
255
256        * Fixed a bug where the GeoSPARQL construct functions did not return the datatype
257        geo:wktLiteral datatype but strdf:WKT.
258
259Tue Mar 26 13:28:26 2013   Pyravlos Team
260
261        * Version 3.2.8 released.
262
263        * Added support for handling (storing/querying) GeoSPARQL datatypes.
264        (bug #31: http://bug.strabon.di.uoa.gr/ticket/31)
265
266        * Fixed a bug in StoreOp that wouldn't close the connection, neither
267        rollback the transaction upon an exception. This had as a side effect
268        the abnormal termination of StoreOp (through for example the use of
269        Ctrl-C signal) which was leaving the database locked.
270
271        * Fixed bug where spatial aggregates (e.g., union) didn't work as
272        expected when the query didn't contain a `GROUP BY' clause.
273        (bug #22: http://bug.strabon.di.uoa.gr/ticket/22)
274
275        * Updated GeoSPARQL namespaces and fixed function names to comply with
276        the GeoSPARQL specification.
277        (bug #25: http://bug.strabon.di.uoa.gr/ticket/25)
278
279Wed Jan 09 18:06:41 2013   Pyravlos Team
280
281        * Version 3.2.7 released.
282
283        * Add an extension function
284        <http://strdf.di.uoa.gr/extensions/ontology#diffDateTime> for computing the
285        span (in milliseconds) between two timestamps.
286
287        * Added an <endpoint-exec> module. This module builds an executable jar file
288        with an embedded Apache Tomcat 7. To create and run the executable jar just
289        type:
290                $ mvn clean package
291                $ java -jar endpoint-exec/target/strabon-endpoint-executable-*.jar
292
293        * Modified strabon script and postgis/monetdb.StoreOP class to get an
294        option for storing a RDF file in a named graph. Moreover, the RDF
295        format of the input RDF file now is given as an option (still, if it
296        is missing, it is assumed that the input is in N-TRIPLES format). The
297        option for the format is -f and the option for the named graph is -g
298        (takes a URI as an argument).
299
300        * Modified the names of the stSPARQL extension functions that
301        utilize the minimum bounding boxes of the involved geometries.
302
303Tue Dec 11 19:33:45 2012   Pyravlos Team
304
305        * Version 3.2.6 released.
306
307        * Modified the names of the stSPARQL extension functions to comply 
308        with the OGC Simple Features Access standard.
309
310Tue Dec 11 00:11:43 2012   Pyravlos Team
311
312        * Version 3.2.5 released.
313
314        * Added support for querying temporal information. This functionality
315        may be found in the `temporals' branch.
316       
317                The datatypes <http://strdf.di.uoa.gr/ontology#period> and
318                <http://www.w3.org/2001/XMLSchema#dateTime> are used to
319                represent periods and instants respectively.
320       
321                The valid time time of triples is represented using quadtruples,
322                with the valid time annotation(instant or period) being the
323                fourth element of the quad. In the same way, temporal triple
324                patterns are used in queries to retrieve the valid time of
325                triples.
326               
327                Some functions have been renamed (their URIs have changed) to
328                follow the names of the respective relations of Allen's
329                interval algebra and other functions have been added.
330               
331                The following temporal functions are supported:
332                during, periodOverlaps, equalsPeriod, nequalsPeriod, adjacent,
333                before, after, overleft, overright, meets, starts, finishes,
334                period_intersect, period_union, preceding_period, and
335                succeeding_period.
336       
337        * Changed behaviour of Strabon and Strabon Endpoint for connecting to
338        a spatially-enabled database. Only one instance of Strabon is allowed
339        at a time.
340
341        * Implemented a Java client for Strabon Endpoint. The client should be
342        used only with endpoint versions >=3.2.5. The implementation may be
343        found int the `endpoint-client' submodule of maven. Currently, only
344        querying of Strabon Endpoints is supported.
345
346        * Added support for requesting the capabilities of Strabon Endpoint
347        (fixes Bug #20 <http://bug.strabon.di.uoa.gr/ticket/20>). See
348        changesets f840796400bf and ?<TBC>? for specific details and how you
349        can determine the capabilities of older endpoints (versions <= 3.2.4).
350
351        * Updated KML writer to include the projected variables of an stSPARQL
352        query in "ExtendedData" and "Data" tags. This is the proper way to
353        do it if we need to convert a KML to a ESRI shapefile and also include
354        such information as attributes for a feature. See related pages from
355        KML specification:
356                <https://developers.google.com/kml/documentation/kmlreference#extendeddata>
357                <https://developers.google.com/kml/documentation/extendeddata>
358
359        * Added user authentication for storing RDF data through Strabon
360        Endpoint. The credentials are specified in
361        WEB-INF/credentials.properties file.
362
363        * Strabon Endpoints now limits the number of the results to a maximum
364        one. The maximum number is specified in the beans.xml file. This
365        corresponds to parameter "maxLimit". The endpoint script has also been
366        updated correspondingly; the limit can be given using the option "-l".
367        One can disable limiting of query results, by setting the "maxLimit"
368        parameter to 0. Addresses Bug #6
369        (<http://bug.strabon.di.uoa.gr/ticket/6>).
370
371        * Added "Known Issues" section to README.
372
373        * Added -m (more memory) and -M (much more memory) options in strabon
374        script for out-of-memory exceptions.
375
376        * Fixed Bug #10 (<http://bug.strabon.di.uoa.gr/ticket/10>). Now
377        KMLWriter handles more geometric types (other than polygons). See
378        changeset 9a3bfee64a39.
379
380        * Menu and navigation in Strabon Endpoint has changed to use jquery.
381        The menu is now populated using the queries placed inside the beans.xml.
382
383        * Added BrowseBean and browse.jsp for browsing the RDF data using the
384        Strabon Endpoint.
Note: See TracBrowser for help on using the repository browser.
