The "MARMOTTA-584/DeveloperDocumentation" page has been changed by Francisco Sumba: https://wiki.apache.org/marmotta/MARMOTTA-584/DeveloperDocumentation?action=diff&rev1=3&rev2=4 '''IN [[http://marmotta.apache.org/kiwi/triplestore.html | kiwi-triplestore ]] module ''' - This is the core of Kiwi TripleStore, in this module the [[https://github.com/cuent/marmotta/blob/MARMOTTA-584/libraries/kiwi/kiwi-triplestore/src/main/java/org/apache/marmotta/kiwi/sail/KiWiValueFactory.java | KiwiValueFactory ]] class was modified to allow storing the geometry literal type from the RDF, in a geometry column of postgres db (Postgis). In the same way to retrieve the geometry literal. + This is the core of Kiwi TripleStore, in this module the [[https://github.com/cuent/marmotta/blob/MARMOTTA-584/libraries/kiwi/kiwi-triplestore/src/main/java/org/apache/marmotta/kiwi/sail/KiWiValueFactory.java | KiwiValueFactory ]] class was modified in createLiteral(...) function to allow storing the geometry literal type from the RDF, in a geometry column of postgres db (Postgis). In the same way to retrieve the geometry literal. To achieve this goal it was necessary to create [[https://github.com/cuent/marmotta/blob/MARMOTTA-584/libraries/kiwi/kiwi-triplestore/src/main/java/org/apache/marmotta/kiwi/model/rdf/KiWiGeometryLiteral.java | KiwiGeometryLiteral ]]. This class lets you create geometry type literals. + + + The following figure is a code fragment of the "createLiteral(...)" function that lets you create a new Geometry Type Literal. + + {{attachment:kiwiValueFactory.PNG}} Moreover, in the STORENODE function of [[https://github.com/cuent/marmotta/blob/MARMOTTA-584/libraries/kiwi/kiwi-triplestore/src/main/java/org/apache/marmotta/kiwi/persistence/KiWiConnection.java | kiwiConnection ]] class, the "node instanceof KiWiGeometryLiteral" conficion was added to filter geometry type literals and insert them into the database with "store.gliteral" statement from [[https://github.com/cuent/marmotta/blob/MARMOTTA-584/libraries/kiwi/kiwi-triplestore/src/main/resources/org/apache/marmotta/kiwi/persistence/pgsql/statements.properties | "statements.properties" ]] file. The "statements.properties" was upgrade to add the new "store.gliteral" statement that allows you to insert the new geometry literal.
