Attendees:

Functional Area E

Functional Area D in Bath is now being used for authority record searching; we are switching ours to Functional Area E.

Review of searches from last meeting:

  • Level 0:
    • E.0.1. Author Search - Keyword
    • E.0.2. Title Search - Keyword
    • E.0.3. Subject Search - Keyword
    • E.0.4. Any Search - Keyword
  • Level 1:
    • E.1.1. Author Search - Keyword with Right Truncation
    • E.1.2. Title Search - Keyword with Right Truncation
    • E.1.3. Subject Search - Keyword with Right Truncation
    • E.1.4. Any Search - Keyword with Right Truncation
    • E.1.5. Author Search - Unanchored Phrase
    • E.1.6. Title Search - Unanchored Phrase
    • E.1.7. Subject Search - Unanchored Phrase
    • E.1.8. Any Search - Unanchored Phrase

Level 1:

E.1.9. Standard Identifier - Keyword

Uses: Searches standard identifiers such as ISBN, ISSN, ERIC, etc., but does not identify a specific standard number scheme.  Servers can choose which standard identifiers to index to support this search.

Attribute Type Attribute Values Attribute Names
Use (1) 1007 identifier-standard
Relation (2) 3 equal
Position (3) 1 first in field
Structure (4) 1 phrase
Truncation (5) 100 do not truncate
Completeness (6) 1 incomplete subfield

E.1.10 Date of Publication Search

Uses: Searches for the year in which a resource is created.

Possible Field Names: Publication Year, Creation Year, Start Date, End Date (journal start and end dates)

The Date of Publication Use attribute must be used as a search limiter in conjunction with another operand (i.e., used to limit a search using other Use attribute values). Z-servers may reject a query that only includes the Date of Publication Use attribute.

Attribute Type Attribute Value Attribute Name
Use (1) 3 date of publication
Relation (2) 1, 2, 3, 4, 5 less than, less than or equal, equal, greater than or equal, greater than
Position (3) 1 first in field
Structure (4) 4 year
Truncation (5) 100 do not truncate
Completeness (6) 1 incomplete subfield

(If vendors have a mmddyy date, can they get the yyyy date that is required here? Are they compliant if they don't translate to the yyyy format?)

E.1.11 Language Search

Uses: Searches for a phrase that indicates the language of the resource.

The Language Use Attribute must be used as a search limiter in conjunction with another operand (i.e., used to limit a search using other Use Attribute values). Z-servers may reject a query that only includes the Language Use Attribute.

Attribute Type Attribute Value Attribute Name
Use (1) 1105 DC-Language
Relation (2) 3 equal
Position (3) 3 any position in field
Structure (4) 2 word
Truncation (5) 100 do not truncate
Completeness (6) 1 incomplete subfield

Checked Dublin Core - DC-Language (1105) to see if it supports a phrase search; DC actually uses a 2-letter code for language, so changed to word search

Add to the beginning of the document: Written with Texas databases in mind. TexShare has at least one database written in Spanish. Written for databases in which the citations are in a single language.

E.1.12 Source Search - Title-Host-Item

Uses: Searches for a phrase that indicates the language of the resource, e.g., journal titles, conference titles, book titles.

Attribute Type Attribute Value Attribute Name
Use (1) 1033 Title-host-item
Relation (2) 3 equal
Position (3) 3 any position in field
Structure (4) 1 phrase
Truncation (5) 100 do not truncate
Completeness (6) 1 incomplete subfield

E.1.13 Availability of Items with Full-text Search

Check with OCLC to see how they do this; we expect a Yes/No or a flag

Maybe ask ZIG for new use attribute

Attribute Type Attribute Value Attribute Name
Use (1) ? Full-text
Relation (2) 3 equal
Position (3) 3 first position in field
Structure (4) 2 word
Truncation (5) 100 do not truncate
Completeness (6) ?? Complete subfield

Talked about adding a Date Range Search.  

  • Used in NISO and Bath; many of their records have a Date 1 and Date 2, so a range search is necessary
  • In these types of databases, we rarely have two dates
  • This search is not needed

E.1.14. Resource Type Search - Phrase

Uses: Searches for phrase that indicates the type of resource, e.g., journal articles, conference papers, world-wide web resource.

Attribute Type Attribute Value Attribute Name
Use (1) 1031 Material-type
Relation (2) 3 equal
Position (3) 3 any position in field
Structure (4) 1 phrase
Truncation (5) 1 right truncation
Completeness (6) 1 incomplete subfield
  • Checked into Dublin Core DC-ResourceType, but it isn't robust enough for our needs.
  • Asked others to check their databases to see what types of information are in these types of fields; there is no standard; some values are phrases, so decided to code this as truncated phrase search

Level 2:

Discussed including a search or limiter on Audience; however, we weren't able to find enough data to understand how this might work

Discussed the possibility of a Name Search – Unanchored Phrase. However, we determined that vendors generally cannot differentiate between topical and name subjects, so decided not to implement this yet.

Discussed the possibility of including searches for each controlled vocabulary, but it is not necessary in this environment

E.2.1 URL Search

Uses: Searches for a complete or partial Uniform Resource Locator.

Attribute Type Attribute Value Attribute Name
Use (1) 1209 Identifier - URN
Relation (2) 3 equal
Position (3) 3 any position in field
Structure (4) 108 string
Truncation (5) 3 left and right truncation
Completeness (6) 1 incomplete subfield

Ask Ray Denenberg what the best use attribute is for this search and what is the best attribute combination to use when searching URLs with truncation.

Check SilverPlatter, Ebsco, and OCLC to see what attribute combinations they use for URLs

FYI: Want to to be able to put in a string of characters, e.g., nasa.gov and find jpl.nasa.gov and trk.nasa.gov and www.nasa.gov

We discussed including Publisher Name Search - Keyword, but decided this was more useful in a native interface for a single database; less so in a broadcast search; so we didn't include it

Scan

  • We found no paragraph explaining scan in NISO; it isn't intended for broadcast; need to ask Bill if this is true for NISO and Bath;
  • Can we view a browse list for titles, authors, subjects?

E.2.SCAN.1 Author – Exact Match

Uses:To browse an ordered list of words that contain the name of a person or entity responsible for a resource.

Attribute Type Attribute Value Attribute Name
Use (1) 1003 author
Position (3) 1 first in field
Structure (4) 1 phrase

E.2.SCAN.2 Title – Exact Match

Uses:To browse an ordered list of words that contain the titles of resources.

Attribute Type Attribute Value Attribute Name
Use (1) 4 title
Position (3) 1 first in field
Structure (4) 1 phrase

E.2.SCAN.3 Subject – Exact Match

Uses: To browse an ordered list of subject-type words (e.g., descriptors, identifiers, subject headings).

The termlist for a Subject Exact Match Scan is:

Attribute Type Attribute Value Attribute Name
Use (1) 21 subject
Position (3) 1 first in field
Structure (4) 1 phrase

In browse, need to check to see if structure is word or phrase in Ebsco, OCLC or SilverPlatter 

Look at wording -- Virginia, Sheila, Kevin and Bill; then send to some vendors for feedback

Z Texas Profile

  • Need to update Z Texas to come into compliance with NISO and Bath; keep the name of the search in Z Texas; link directly to the search in the NISO profile
  • Discussed differences in format searches in Bath and NISO; decided that we needed a phrase search that will retrieve data from MARC subfields that do not necessarily use controlled vocabulary, e.g., 245 |h

Z Texas Client

Virtual Union Catalog

  • Valerie Johnson leaving TSLAC; Kevin Marsh will be covering some of her work until the position is filled

Interoperability Testbed

Title for Functional Area E - Profile for Searching Citation Databases

  • databases can have full-text attached, but just searching the citation
  • not searching citation databases like SSCI or SCI
  • Think about it

Next Meeting:

  • May not need one, so none scheduled
  • Small group will look over a draft of the profile
  • After changes are made, will send the profile our for comment to interested vendors
