About?
• Original intent: talk about technical work at LANL
• But LANL is sooooo different:- Local storage of Terrabytes of content- Local creation of services over that content
⇒ Whatever LANL does, doesn’t apply to other libraries

About?
• In this keynote, I will:• Show that many libraries will soon be in a quite similar
situation• Explore the characteristics and consequences of that
situation• Focus on fundamental infrastructure
• Structure:• Slides that make the major arguments• Sidebars that illustrate (related) thoughts

The repository model
Before they know it, institutions will be swamped with digital information of all kinds
Libraries seem to be the natural parties to take care of this
Vast growth of digital collection:
• Local repository (ies)• Thousands of remote
repositories

Value chains starting in repositories
• New knowledge is really being created when allowing for non-anticipated use of stuff.
• These repositories are not about creating services for local users (only)
• These repositories are not about creating a service (user interface) for all users
• These repositories are about facilitating the use of materials in many contexts
• These repositories are the starting point of value chains

• Journal system is just one possible, vertically integrated value chain
• In a networked world, the functions it performs can/will be handled in a deconstructed/distributed manner:
o registration in repository
o validation by different nodes/parties
o archiving by different nodes/parties
o awareness by different nodes/parties
Example: scholarly communication value chains

Value chains starting in repositories
• Lesson learned:
To allow value chains to emerge on the basis of materials in repositories, those repositories need a clear/clean machine interface that allows downstream applications to consume materials, aggregate them, build services, …
⇒ Disconnection of repository content and service: allows for creation of both local and remote services
⇒ On-Web: Protocol-oriented interface⇒ These value chains are about the real stuff not (only) about
metadata

• When facilitating the (re)use of materials (not just metadata) IP concerns increase significantly:
• Data authenticity• Data integrity• Usage rights
• Need machine readable rights expressions:• Robots are the next generation readers• Even when materials are “free”• Object-level expressions• The world of CC, MPEG-21 REL. ODRL, XRMLo NISO meeting to explore needs of scholarly community in this
realm

Rights
• Urgent need for an environment in which scholarly assets behave in a manner that matches the “gift exchange” spirit of scholarship.
• James Boyle: Think about what we loose by sticking with the current paradigm!
o enormous constraints on ability to use scholarly assets: process to extract knowledge, attach knowledge, mine, evolve, build upon: robots are the next generation readers

Standards
• Standards are the glue that holds the networked information environment together.
• Standards are crucial to facilitate the emergence of improved and integrated services across repositories.
• As the information environment becomes more complex, and as we move towards new levels of services, we will need more, not less standards.

• Standardization efforts/bodies in our community are seriously challenged:
o Many standards defined outside our community.o Lack of impact on major standardization bodies of the
networked world (W3C, IETF, IANA, …)o Problems to interconnect within and amongst related
efforts in our community: digital library, grid computing, e-learning, library automation, …
o Operational models/processes not adequately adapted to the realities of the networked world (cf. patent challenges OpenURL, MetaSearch)
o Funding for standardization efforts and related infrastructure is very hard to find (cf. OAI, CIMI, info URI Registry, OpenURL Registry, …)

The repository model
Explore (some of) the characteristics & consequences of this model:
• Value chains starting in repositories
• Local capacity• Archiving• Rights• Interoperability• Standards

A content-node & service-node ecology?
• Content nodes:o Libraries become content-nodes, capturing the
intellectual output of their parent institutions and “exposing” it.
o Vision: A network of federated repositories that makes available the collective intellectual output of faculty and researchers of the world's research institutions
o Ongoing with the Institutional Repository movemento Libraries must act in this realm

A content-node & service-node ecology?
• Service nodes:o Need services (value chains) to emerge on top of tat
contento “If the content is on-Web, the services will bloom”o Can not solely rely on … euh .. Google Scholar• Service node tasks include:
- indexing, searching, recommendation, linking, data-mining, visualization, … nodes
- annotation, certification, metric-collecting, rewarding, … nodes
- archiving, normalization/transformation, … nodes• Vision: A federation of networked services - in which
Libraries take on specific service tasks - that turns into a global scholarly value chain

The repository model
Physical libraries:• Local storage of content originating with 3rd parties• Facilitate use of that content by local user base
Current libraries:• Remote storage of content originating with 3rd parties• Facilitate use of that content by local user base
Repository model libraries:• Local storage of content that originates in-house• Facilitating its use by remote and local users by facilitating the
emergence of services
Emergence of a quite fundamental new library model
