    1. Questions

 

  1. ECDL report
    1. Keynote on WebBase Project (Stanford)
    2. Key challenges

                                                               i.      Scalability (crawling, archive distribution, index consistency, storage)

                                                              ii.      Consistency (freshness, version control)

                                                            iii.      Dissemination

                                                            iv.      Topic-specific collection building (e.g., collection synthesis, tunneling)

                                                             v.      Archiving (units, coordination/interoperation)

                                                            vi.      IP management (copy access, link access, access control)

                                                          vii.      Quality (authenticity, authority control, stamps of approval)

1.        authenticity functions (reputation index, webs of trust)

2.        majority voting

3.        time-based authenticity—time stamps (requires trusted 3rd party)

4.        how to evaluate?  Note distinctions from humanities DLs

    1. Parallel crawling approaches

                                                               i.      Independent (too much redundancy)

                                                              ii.      Partitioning

                                                            iii.      Cross-over (the overlaps come after the partitions have been finished)

                                                            iv.      Partition exchange (crawler sends messages to other crawlers in different partitions)

 

 

  1. Assessing User Needs
    1. Library of Congress NDL Project  http://ils.unc.edu/~march/revision.pdf

                                                            vi.      Transaction log analyses
