UK Legal Deposit Libraries Act 2003

• For the deposit of digital materials, this was an
  Enabling Act' i.e. it gives the force of law to
  suitable future Regulations, but has no effect
  until these have been drawn up and approved.
• No precise timetable for when Regulations for
  different types of material will be passed

Voluntary Deposit (VDep)
1999 LandLine

• OS digital data contracts

2006 OS MasterMap

Repositories in the Legal Deposit Libraries

• Isnt this data already being archived?
• The Ordnance Survey?
• The National Archives?
• EDINA?

Repositories in the Legal Deposit Libraries
The Digital Object Management Programme (DOM)

• Providing a generic and cost-effective
  infrastructure for the Librarys digital
  material that will
• take in material of many types
• take in material coming from many sources
• store it all securely for the long term
• allow controlled access
• endure
• The current budget is 1.5m per year.

Repositories in the Legal Deposit Libraries
Trusted Digital Repository (TDR)

• July 2006 project initiated with funding from
  the Scottish Executive
• A range of digital data, including items
• received under legal deposit legislation
• from other Scottish cultural institutions
• digital images of NLS collections NLS TDR
• The current budget is 1.8 million for
  development over two years.

• Software 2 - functionality and content 2006-
   
• Negotiation with OS on functionality, use of
  small-scale mapping and OS MasterMap layers
• NTF (1999-2005) and GML (2006-) annual snapshots
  converted to MapInfo TAB files (using TranspOSe
  and InterpOSe)
• Duplicated annual snapshots - not a growing
  database of feature-level information

and OS MasterMap formats for storage and use

• Some Questions!
• Are snapshots acceptable archivally compared to a
  growing, managed repository of tiles and
  features?
• Is an annual snapshot a sufficiently
  comprehensive record of landscape change?
• When should we migrate NTF data, and to what?
• What metadata should be used for geospatial data
  in our LDL repositories?
