OBAA STANDARDWhere are we?

Tiago PrimoGIA – Grupo de Pesquisa em Inteligência ArtificialUFRGS

First Stage (Base) 2008 - 2009

First Stage Accomplishments A set of metadata based on LOM / IMS

Extensions with: Technical Metadata Educational Metadata Accessibility Metadata Multimedia Segmentation

Metadata Profiles Mandatory and Optional Approach

Repository Federation ( FEB ) Dublin Core to OBAA conversion and index OBAA Native Linked with

LUME ( Digital Repository UFRGS ) CESTA ( Learning Technologies repository ) OBAA ( Project repository ) BIOE ( International bank of educational objects ) BNDIGITAL ( Digita Brasil national library ) ENGEO ( Geotechnical engineering learning objects repository) ( Ongoing)

Implementing OBAA Repositories OTICSSS ( Information Technologies and communication on Health Services and Systems)

Why Profiles?

Definition of metadata sets to help at the authoring process (PM) E.g. What metadata are necessary to

accomplish maximum interoperability Provides a set of technical

recommendations to help at the authoring process ( PT ) E.g. How a learning object must be designed

to accomplish maximum interoperability OBAA Stamp Certification

Interoperable Learning Objects

Repository and Repository Federation

Repository Federation Reuse of learning objects One place to find all LO’s through indexed repositories OBAA Native LDAP protocol (today) OAI Interface ( ongoing work ) DSPACE integration ( ongoing work ) Dublin Core to OBAA conversion

OBAA Current Repository ( under development ) Build with DSPACE Technology FULL OBAA metadata schema Compatible with OAI communication protocol

OBAA Repository (Beta / Offline )

Build With DSPACE

Compatible with other DSPACE repositories

OBAA FULL Native

Repository Federation (ONLINE)

Learning Objects Interface Tool (BETA)

Functionalities

Uses OBAA Metadata

Converts Dublin Core to OBAA

Uses BIOE Objects

Allow the users to search its LO repository

Allows the catalog of new LO that are OBAA core compatible

OWL Ontology

The OBAA standard metadata is already described on a OWL-DL Ontology and available for download.

Metadata Profiles and Technical Recommendations Rules are being described

Stage 2 Ongoing Work

Connects several repositories and provides a standard technical instruction based on OBAA MetadataProvides metadata and technical instructions to build Learning Objects OBAA compatiblePopularize the OBAA PortalRefines the OBAA Ontology and add semantic metadata informationImproving our metadata schema ( Accessibility, Rights, PM & PT)Privacy Issues

Sample Steps

Recover a FOAF/OBAA profile through OAI Communication

Recover a OWL Ontology ( Apply reasoning algorithms to understand the context of the user)

The ITS will filter all the possible recommendations and search on external repositories ( through OAI ) other possible LO to recommend

The user receives a personalized recommendation independent of ITS, since that ITS uses the OBAA structure.
