Editing with TopBraid EVN
How to add, delete, and edit concepts with TopBraid EVN. Also: how to navigate and search vocabularies, and how to see a history of edits made.

Using TopBraid to Create Linked Data for the
US Government Spending Data
A short tutorial from Dean Allemang, Chief Scientist
of TopQuadrant, on how to combine data from USAspending.gov, with
FEA and US Government ontologies from oegov.org. Through the power
of RDF and OWL and the software capabilities of TopBraid, data
consolidation, reporting and other insight discovery are

Creating a SPARQLMotion Web Service for
Data Transformation: Part 1
This video demonstrates a SPARQLMotion web service
that imports a spreadsheet, transforms it by running SPIN rules and
outputs an RDF graph. The service demonstrated here is generic. It
can convert any input into any output. To use it with a different
input, simply change the arguments: URI of the input (source) and
URIs for the schema and the transformation rule set. Transformation
rules shown here were created with the SPINMap feature of TBC.
Alternatively, they could have been written by hand as SPARQL
queries or templates.
View Demo (~8 minutes)
After seeing the video, you can try the service
downloading the example TopBraid Composer project. Unzip it into
your TBC-ME workspace and make sure that there is no more than one
xform.ex1.topbraid.com folder in the unzipped folder hierarchy.
Right click in the Navigator view in TBC and select Import… In the
Import dialog, select General > Existing Projects into Workspace and
click Next. On the Import Projects page, browse to your workspace
location, select the unzipped project folder and click on Finish.
You will now see the new project in the Navigator.
Source for this web
service can be not only a spreadsheet as shown in the video, but any
other file TopBraid is able to auto-convert to RDF. This includes .xml
files and, of course, any serialization of RDF. The output module
creates a new file at the specified path inside the workspace and
with the specified base URI. The serialization is derived from the
file name according to TopBraid's conventions, e.g. files ending
with .ttl will be written in Turtle format. This includes writing
out .xls and .xml files.
Creating a SPARQLMotion Web Service for
Data Transformation: Part 2
describes how to create a SPARQLMotion web service. SPARQLMotion is
a way to create semantic data transformation and data integration
services. We create a RESTful service that takes a source file,
performs some transformations and produces the output.
The script was demonstrated in the part 1.
In this video we focus on how to create such a service.

Creating a SPARQLMotion Script
This 5-minute video demonstrates how to create a SPARQLMotion script with TopBraid Composer Maestro Edition. We start by importing a news feed and then convert the resulting RDF triples into a spreadsheet file. While doing so, we also explain the graph editing capabilities. View
(Note: since this recording was made, we have
added a wizard for more conveniently creating scripts. To create the
script one no longer needs to start with an empty file and do
import. It is now simply about selecting New -> RDF/SPARQLMotion
file from the menu. All the needed imports are done automatically.)

SPINMap: SPARQL-based Ontology Mapping
This video tutorial introduces SPINMap, a SPARQL-based
mapping language to describe transformations between two RDF or OWL
ontologies. SPINMap is using SPIN templates and functions as a
declarative mapping modeling language. These mappings can be edited
either graphically or directly on RDF level. SPINMap models can be
edited with TopBraid Composer SE, but executed with TBC Free Edition
or the open source SPIN API.

Getting Started with TopBraid Composer
Walks through the basic steps after Composer has been installed. In this demo we create a new project with an OWL file, then we create classes,
properties and instances and show how to access visualization and source code. View
Geography and Mapping Support
This video demonstrates how to access geospatial information with Composer. We assign geographical coordinates to resources from a map and then perform some types of queries to find resources with specific logical characteristics. View
This video shows how to use TopBraid's spreadsheet importer to lift tabular data into an OWL ontology. View
Importing arbitrary XML files
This screencam demo shows how to import an XML file into TopBraid Composer (Maestro Edition), runs a SPARQL query over the XML data and performs other transformations. Finally, an HTML file is imported to OWL. Note that this video still uses the term xmap for what we now call Semantic XML. View
Linking with DBpedia
This short video demonstrates how to link a domain model with corresponding DBpedia pages. This feature can be used to link existing ontologies and instances with other Semantic Web vocabularies. View
