What is Cultivate Interactive?

• Cultivate Interactive is a pan-European Web
  magazine launched in July 2000
• It is aimed at the European digital cultural
  heritage community

How is it Delivered?

• The magazine method of delivery is intended to
  promote consistency, low maintenance and reuse.
• Windows NT 4 Server
• Site Server 3.0
• IIS 4.0
• Active server pages (ASP)
• Server-side Includes (SSIs)
• XHTML
• Future database integration

5
Storing the Metadata

• Dublin Core metadata is recorded for each article
  in a default file.
• Recently we have also imported this metadata into
  a database

' Give the Author metadata in format Surname,
initials author "Crane, G., Fuchs, B.,
Smith,A.C. and Wulfman, C.E." ' Give the
Description metadata (in single line) description
"Gregory Crane, Brian Fuchs, Amy C. Smith and
Clifford E. Wulfman discuss the symbiosis between
content and technology in the Perseus Digital
Library."

Using the Metadata

• This data can be used in a number of ways.
• Resource discovery
• Advanced searching within the magazine
• Getting harvested by Search engines
• Using with Open Archives Initiative (OAI) or
  other metadata harvesting services e.g. CSC
  document server
• Auditing purposes
• Reuse of information
• Database
• Similar articles

7
Searching the Metadata

• The data searched in different fields is based on
  the field's respective Dublin Core attribute e.g.
  The Abstract search is based on the
  DC.Description Dublin Core attribute.

• Main Search screen
• Full text searches
• Search just the author, title or abstract fielda
• Advanced search
• Search by category, issue, article type or
  project category

OAI and NOF

• All OAI (Open Archives Initiative) data providers
  supply metadata in a common format - unqualified
  Dublin Core
• Harvested by the NOF portal - remember Petes
  slides
• Possibility of harvesting clusters
• Its not rocket science
• NOF Portal will drive traffic to your site
• Howevermetadata shouldnt be managed ONLY with
  the OAI portal in mind - we still need to create
  rich metadata

Metadata Tools

• For creating, editing, seeing and managing
  metadata
• Stand-alone metadata tools
• Web-based - CGI, Java applets
• Desktop - Java, Visual Basic
• HTML or text editors
• tedious, hard to do bulk-changes
• Web site management tools
• NetObjects Fusion, FrontPage
• Home grown solutions based on SSIs

10
Things to Bear in Mind

• Who will be maintaining your metadata?
• Authors
• Webmaster
• Registry
• The Library
• Which pages should have embedded metadata?
• All?
• 'Home' pages?
• Selected pages?
• Just the university home page?

Hands-on Session

• Looking at metadata creation tools
• Looking more at traditional metadata for resource
  discovery
• Also metadata for management of resources
• Lots of issues, for example preservation -
  include information on how the image is captured,
  rights, workflow etc.
• Try and keep clear what we are doing to the
  metadata
• Creating metadata
• Managing metadata
• Using/searching metadata
