Building a Middleware for Heterogeneous OpenCourseWare Metadata Systems

This paper discusses the development of a middleware solution designed to standardize metadata for heterogeneous OpenCourseWare (OCW) systems. Authored by Ya-Hui Tang, Yan-Hua Jang, and Hsu-Tien Wan from the Office of Biomedical Informatics at Taipei Medical University, the work highlights the challenges of existing OCW systems, particularly in Taiwan. The middleware transforms metadata from various formats (TMU’s to TOCWC), ensuring compliance with standardized models. Key features include data collection, import/export functionalities, and significant efficiency improvements in metadata management.

  1. Building a middleware for heterogeneousOpenCourseware metadata systems Ya-Hui Tang, Yan-HuaJang and Hsu-Tien Wan Office of Biomedical Informatics, Taipei Medical University 1/21/2013

  2. OCW in TMU • Starts from 2007 • eduCommons 3.2.1

  3. EduCommons 3.2.1 vs. 4.1.1 • Verson 3.2.1 • Easy • Fast • Stable • Verson4.1.1 • Institutional • Layout

  4. OCW in TMU 72 62 59 11 1

  5. GA Report (NOV 1, 2012~JAN 10, 2013)

  6. Institutional Collaboration in Taiwan OCWC • Building Standardized Metadata Model for OCW • Building Cloud Reporting Aggregator for OCW

  7. Standardized Metadata Model LOM vs. TWLOM and TOCWC metadata model

  8. 8 categories • 47 fields: • 11 must fill fields • 12 systemic values

  9. TOCWC Metadata system

  10. Heterogeneous Systems • We all build our own OCW systems that is not follow the standards. middleware middleware

  11. Transform metadata from TMU’s to TOCWC’s

  12. Data Collection • Key-in page • Simple • Import Data

  13. Export Transforming Metadata

  14. Reuse the metadata

  15. The Next Step • Upload metadata that fit TOCWC’s standards. • Generated metadata sets according to different platforms. • Build once, reuse many times.

  16. Thank you for your Listening!
