Topics of discussion:

• Review of 4th draft of the Bib-2 Attribute Set and revised casting of the MARC Attribute Set
• MARC attribute set (Joe Zeeman)
  • 9 new types defined
  • schema of MARC record is specified, and can define subschema (MARC variants)
  • can specify sub record identifiers, tags, indicators, sub fields, offset, etc.
  • can express search for data starting at an offset in a given field or sub field, etc.
  • tried to do this without defining new types but needed new types to be consistent with the new attribute architecture
  • adding new attribute types may require this to be a new class of attribute sets
  • attribute architecture documents indicate that a new attribute set can define new types, but must carefully define relationships
  • there were previously 12 existing types for a class 1 attribute set of class 1.
  • attribute type is an integer in the ASN.1, so attribute types must be numbers
  • MARC attribute set could be used with Bib-2 in the same query, but not in same term; not allowed to mix attributes from different classes in the same attribute list (for a single term) but could not mix Bib-1 and Bib-2
• Bib-2 Attribute Set
  • Attribute set for the bibliographic domain
  • Following the new attribute architecture
  • Bib-2 should handle searching both MARC and non-MARC databases
  • Makes extensive use of utility and cross-domain attribute sets
    • draws on the access points in the cross-domain attribute set
    • adds qualifiers to be used with cross-domain attributes
  • Latest version of Bib-2 attribute set removed attributes which were specific to MARC conventions
  • Music access points separated into a separate music attribute set, perhaps a subset of Bib-2?
    • Chemical access point attributes not included in Bib-2
    • University of California is using STAS attributes, but within the context of Bib-1 attribute sets
    • Parties working with chemical databases could prepare chemical attribute set similar to what has been done for music access points.
    • Access point attributes specifically for use with citation databases are not included in Bib-2
  • Thus, list of basic Bib-2 access point attributes is short
• Issue of separating Bib-2 from MARC into separate sets
  • A search might include use of both MARC and Bib-2 attribute sets (but not on same term)
  • Add attributes for a few specific MARC codes back into Bib-2 list.
• Add Bibliographic Level and Nature of Contents as semantic qualifiers for the Cross-Domain Resource Types
• Add content authorities and qualifiers for the Cross-Domain Format access point, to cover the various lists of media types enumerated in ISBD, MARC21, and the IANA Media Types list
• Qualifiers for Bib-2 access point ôNumberö and Cross-Domain access point ôResource Identifierö are almost identical. More work is needed to separate out the content authorities used for these two lists.
• Use existing lists such as MARC Relators, Sources, and Description Convention Codes, as registries for Content Authorities
• LC maintains these lists. Ask Ray how to ask LC to add missing values.
• Include in lists of content authorities in Bib-2 only those values not already specified on other authority lists
• Look at other registries for appropriateness, to see if they can be referenced.

Two hour meeting didn't give us enough time. Detailed discussion on the 1st draft of the Attribute Set for Searching Materials is still pending.

Barb Shuh and Lennie Stovel agreed to continue work on Bib-2 with regular conference calls. Joe Zeeman will participate when available.
