GeoKnow Generator 2nd Year Releases

The second year of GeoKnow has passed and we have several new releases to announce. Among new software tools there are:

FAGI-gis 1.1+rev0
FAGI aims to provide data fusing on geometries of linked entities.
This latest version provides several optimisations that increased
the scalability and efficiency. It also provides a map-based interface
for facilitating the fusion actions through visualisation and
filtering of linked entities.
RDF Data Cube Validation Tool 0.0.1
Validation tool aims to ensure the quality of statistical datasets.
It is based primarily on the integrity constraints defined by the
RDF Data Cube vocabulary, and it can be used to detect violations
of the integrity constraints, identify violating resources, and
fix detected issues. Furthermore, to ensure the proper use of
vocabularies other than the RDF Data Cube vocabulary, it relies
on RDFUnit. It can be configured to work any SPARQL endpoint,
which needs to be writeable in order to perform fix operations.
However, if this is not the case, user is provided with the SPARQL
Update query that provides the fix, so that it can be executed
manually. Main purpose of the tool within the GeoKnow project
is to ensure the quality of input data that is to be processed and
visualized with ESTA-LD.
spring-batch-admin-geoknow 0.0.1
The spring-batch-admin-geoknow is the first version of batch processing
component that functions as the backend of the Workbench’s.

Besides brand new components, there are also new releases also available as Debian packages:

virtuoso-opensource 7.1.0
Virtuoso 7.1.0 includes improvements in the Engine (SQL Relational Tables and RDF Property/Predicate Graphs); Geo-Spatial support; SPARQL compiler; Jena and Sesame provider performance; JDBC Driver; Conductor CA root certificate management; WebDAV; and the Faceted Browser.
linkedgeodata 0.4.2
The LinkedGeoData package contains scripts and mapping files
for converting spatial data from non-RDF (currently relational)
sources to RDF. OpenStreetMap is so far the best covered data
source. Recently, initial support for GADM and Natural Earth were

  • Added an alternative lgd load script which improves
    throughput by inserting data into a different schema first
    followed by a conversion step.
  • Optimized export scripts by using parallel version of pbzip.
  • Added rdfs:isDefinedBy triples providing licence information
    for each resource.
Facete2-tomcat7 0.0.1
Facete2 is a web application for exploring (spatial) data in SPARQL
endpoints. It features faceted browsing, auto detection of relations
to spatial data, export, and customization of which data to

  • Context menus are now available in the result view enabling
    one to conveniently visit resources in other browser
    tabs, create facet constraints from selected items and copy
    values into the clipboard.
  • Improved Facete’s autodetection when counting facets is
    infeasible because of the size of the data
  • Suggestions of resources related to the facet selection that
    can be shown on the map are now sortable by the length
    of the corresponding property path.
facete2-tomcat-common 0.0.1
This package is a helper package and is mainly responsible for
the Facete database setup. There were no significant changes.
sparqlify-tomcat7 0.6.13
This package provides a web admin interface for Sparqlify. The
system supports running different mappings simultaneously under
different context paths. Minor user interface improvements.
sparqlify-tomcat-common 0.6.13
This package is a helper package and is mainly responsible for
the Sparqlify database setup. There were no significant changes.
sparqlify-cli 0.6.13
This package provides a command line interface for Sparqlify.
Sparqlify is an advanced scalable SPARQL-to-SQL rewriter and the
main engine for the LinkedGeoData project.

  • Fixed some bugs that caused the generation of invalid SQL.
  • Added improvements for aggregate functions that make
    Sparqlify work with Facete.
  • Added initial support for Oracle 11g database.
limes-service 0.5
Limes-services updated to the latest LIMES library. The main enhancement
this year was refactoring the service to provide RESTful
geoknow-generator-ui 1.1.0
First public release of the GeoKnow Generator Workbench extends
the initial prototype by including user and role management,
graph access control management, processing monitoring
within a dashboard.
Deer 0.0.1
GeoLift has been renamed to DEER. The functionalities provided
in GeoLift have been generalised to not only support geospatial,
but generally structured data.

If you need help installing or using components are available as Debian packages in the Linked Data Stack, do not hesitate to join and ask in the linkeddatastack google group.
