Day 9

3/27/00

1.One minutes

Big Point

Q&A/reference services can be auto/human/hybrid

Interoperability includes social dimension

Discarding information is a part of the life cycle

Questions

In addition to auto-expiration, can’t we auto-update for preservation? (version control)

Are not flexibility and consistency at odds in standards?

Triangle DL progress?

Is there a governing body for DLs?

2. Discuss Ask Eric results

3. Interoperation: discuss Paepcke et al

Many layers of representation that require specification/clarification

Standards/mediators

Info mgmt: e.g., thesaurus

Display: e.g., windows, printers

Communication: e.g., TCP/IP, Z39.50

Operations: e.g,, collaborative spaces/blackboards, telepresence

Protection: e.g., logins, watermarks

Aim to think globally, act locally—give each component independence but capability to cooperate

How to measure interoperability?

High degree of component autonomy

Low cost of infrastructure

Ease of contributing components

Ease of using components

Breadth of task complexity supported

Scalability in number of components

Solution classes

Strong standards

Families of standards

Mediation (wrappers, gateways, crosswalks)

Specification-based interaction (formal languages, KIF/KQML)

Mobile functionality (intelligence in the network and in objects/agents)
