Visualization Providers for Ontology ElemenTs (VPOET)

Intro

VPOET lets end-users with basic skills in client-side technologies to create, in a simple way, templates (aka visualizers) for ontology elements. These specialists do not require technical skills on Semantic Web technologies. To know which classes, properties, and relationships are defined in a given ontology, Web designers (aka Visualization Providers (VPs)) can read the information provided by OMEMO. Besides, VPs indicate their design features, specifying details such as dominant colours, behaviour in case of changes in the font size, sizes (preferred, minimum, maximum), or code-type provided (HTML, XHTML, ActionScript). This information is published in RDF format, according to an ad hoc ontology. As any other Fortunata-based application, these semantic data are published automatically. This information can be used by mere mortals by using the HTTP channel.

How to use VPOET

Figure 1 shows a functional schema of VPOET. Rectangles are wiki pages, thin arrows represent actions, and thick arrows are data flows.

If you are a Web designer (with basics on client-side techs. such as HTML, CSS or Javascript), you can create templates for ontologies elements by using this form:VPOETCreateViz. If the ontology you are interested in is not in OMEMO, just add it! (if this is the case some help may be required).

If you are not a Web designer but only interested in using some already created visualizer to render RDF data, use the HTTP channel.

If you know the template (the design ID) and you just want render some data, go to VPOET Visualize Design

See all the stored templates in VPOETStoredData.

Tutorial

If you are new to VPOET, follow the tutorial. Everything is fairly well explained and there are lots of example code and screenshots. Depending on your background in HTML and JavaScript, this tutorial will require between 1-2 hours of your beloved time.
