OBAA STANDARD Where are we? Tiago Primo GIA – Grupo de Pesquisa em Inteligência Artificial UFRGS

First Stage (Base)  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

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 Metadata Provides metadata and technical instructions to build Learning Objects OBAA compatible Popularize the OBAA Portal Refines the OBAA Ontology and add semantic metadata information Improving our metadata schema ( Accessibility, Rights, PM & PT) Privacy Issues
