Software and documentation to deploy NDG services at a data provider. If possible (depending on other projects) this package may include OGC web service software and other data services packaged in with the NDG software.

T13 Product purpose

Project components:

  1. Database backend and associated web services and documentation.
  2. OAI repository software and associated documentation.
  3. NDG interfaces package and associated documentation.
  4. NDG security services package and documentation on how to link to existing user databases or to create one.

Requirements of Data Provider Package

Software components provided by other NDG Workpackages

  • Data extractor
  • Delivery system
  • Database backend and web services
  • Bulk stub-b and DIF creation utilities ( including #32)
  • NDG interfaces
  • Security system

Software components unique to Data Provider Package:

  • Database: eXist
  • OAI provider
  • Just checking: assuming DP Package doesn’t develop any software?
  • More?

Due by milestone: NDG Alpha (June 2006)

This is the initial NDG2 release. Major components should be present.

  1. Nothing.

Due by milestone: Post-Alpha Review

Reviewing how well alpha products were delivered and implemented. Reviewing what changes to product plans, technology etc. may be required in light of experiences at Alpha. Reviewing requirements for MOLES and CSML in remaining NDG2 timescales.

Due by milestone: External Product Definition

Mostly a checkpoint to see if there are any problems before PreBeta and make sure information is available and disseminated.

Due by milestone: PreBeta

This stage is intended to try and pull together the back-end services that make Beta possible.

Due by milestone: Beta

Due by milestone: PostBeta_review

This stage is a review of how we did for beta, what needs doing, and making a public release.

Due by milestone: PROD
