Application Priorities

  • Performance and Cleanup
  • Plone Documentation
  • Image export
  • WYSIWYG (90%)
  • Journal quality (export to file bundle and python

script)

  • Interactive cleaning functionality

Sunsetting

Project development will handoff (next week!) to:

  • CASA group for ongoing development. ALMA

CASA Development Center in Taiwan. EWR to remain on as Project Scientist.

  • NRAO Archive group for ongoing integration
  • ALMA Archive group once NRAO work is done

Lessons Learned

  • Software project management is hard and time

estimates were optimistic (esp., architecture)

  • Integration was effective through partnership with

NRAO and the CASA software group

  • User testing essential but happened too late
  • Currency fluctuations became a major risk
