TaOPis is an open source community project hosting system with an integrated semantic wiki component based on F-logic. It's reasoning engine is FLORA-2 but it is mostly implemented in Python and PHP. PostgreSQL acts mainly as an interaction layer between the three platforms. TaOPis' semantic wiki is based on a fully object oriented framework - any wiki page, any forum post, any blog entry, any user etc. is considered to be a generic object that can be specialized using attribute value tags. Special tags like class or subclass allow for specializing them further with object-oriented semantics and the creation of class hierarchies. Links between objects are considered to be relations. A still not implemented feature (semantic web services) shall provide methods for such objects. Users can query the semantic wiki through F-logic syntax, but agents can also export OWL of FLORA-2 ontologies of a given project. There is also a Facebook application interface available. TaOPis was still under active development as of February 2009.

Contents

[edit] Main wiki characteristics

Is the wiki web-based or a (standalone) desktop application?

  • Web-based

What communities (type/size) is the wiki intended for?

  • Any on-line communities of rather smaller size due to lack of processing power.

Main editing paradigm:


[edit] Standard project info (align with sourceforge attributes)

What is the wiki engine's software license?

  • The wiki engine is ditributed under GPL

What programming language is it written in?

  • FLORA-2, Python, PHP, PostgreSQL

What status is the project in? (project maturity)

  • Prototype

What is the estimated size of the developer community?

  • Currently around 1 main developer and few commenting "co-developers"

What is the estimated size of the installation base?

  • Currently only 1

[edit] Formalization

Are semantics (triples/whatever) separated from or included in the wiki markup?

  • Semantics are partially included in the wiki syntax (links, queries), and partially gathered through tagging

Is the end user supported when formalizing content/adding annotations in some way? autocompletion/proposal generation/schema or consistency checking

  • autocompletion is planned

What representation language is used? (RDF/OWL/...)

  • F-logic and OWL

Is there versioning support for the formalized content?

  • no, but planned

Is there provenance (Herkunft) support for the formalized content? (get formalized contents/triples tagged with its author?)

  • yes

What things can get formalized?

  • any object (wiki page, forum post, blog entry, link/relation, user - implemented but not visible, project/organization - implemented but not visible)

Is there support for typing pages/category system/page tagging?

  • yes, full support for attribute/value tags, creation of classes of objects, subclasses, as well as methods (semantic web services - planned)

Is there support for typing links?

  • yes

What ontology support does the wiki provide?

  • FLORA-2/F-logic, OWL

Is there support for loading/saving ontologies?

  • yes

Can ontologies be created/changed from within the wiki?

  • yes

Is there any reasoning support?

  • yes, FLORA-2 queries integrated into Niklas wiki syntax

Is the instance data required to comply with the ontologies?

  • ontologies are created dynamically and are probability annotated through social network analysis (currently a modified PageRank algorithm is used)

How can semantic information be exploited?

  • page rendering, navigation, search

Is there simple querying support? (search for all triples with a certain subject, predicate, object)

  • simple F-logic syntax

Is there advanced querying support? (free, complex queries) Is there any real user interface for expressing advanced queries?

  • advanced F-logic syntax

Is there any special visualization?

  • planned

Is there any way to render pages from formalized content?

  • queries use semantic templates to render page content (e.g. FAQ, TOC, list of definitions, list of most important terms etc.)
