ISSN: Linking Data and Metadata

Transcription

1 ISSN: Linking Data and Metadata Regina Romano Reynolds NASIG NISO Preconference Phoenix, June 4, 2008

2 Overview More data (content) requires more metadata Metadata needs standardization and quality control in order to function well ISSN and other identifiers can help connect data and metadata ISSN properly used can help keep metadata synchronized so it can work effectively ISSN can be used to clean dirty metadata Access to centralized ISSN data can help keep it clean Ongoing exchanges between libraries and other actors can help keep data and metadata synchronized

3 Connecting Users to Content Credit: Hennepin County Library

4 Metadata Helps Link Users to Content OPACs ERMS OpenURL Knowledge bases A&I services ISSN Portal Metadata Student & citation Full text of article

5 I I want an article Which database to search? Where is it in the A Z list? Listed database does not have full text Multiple hits: which has the issue? The library does not have the article in online form, does it have it in print?

AU: Georg-Kraemer-J-E; Mundstock-E- C; Cavalli-Molina-S {a} SO: Journal-of-Cereal-Science. [print] May, 2001; 33 (3): IS: PY: 2001 AB: Amylase activity and qualitative changes in amylase isoenzymes as a function of barley seedling age were investigated in 10 Brazilian barley cultivars

9 ISSN: Key Metadata Element

10 ISSN Myths ISSN can be assigned to current serials only Publishers self-assign ISSN There is a charge to get an ISSN ISSN is only a U.S. standard (NISO Z39.9) ISSN have been assigned for the past 15 years The ISSN system is controlled by the Library of Congress OCLC records are the best source for ISSN Ulrich s records are the best source for ISSN

11 ISSN Infrastructure 85 worldwide ISSN IC

12 Traditional ISSN Functions Unique identification of manifestations (separate ISSN assigned for each medium) Printed on ink-on-paper issues Searching in OPACs, databases Identifier used by US Postal Service Copyright Clearance Center A&I service citations

19 ISSN Data Problems ISSN of print version in 022 $a of e-resource record ISSN of former title in 022 $a of later title ISSN misprinted by publisher in 022 $a ISSN in CONSER record for non-u.s. title subsequently changed in ISSN Register, not updated in OCLC

23 For display of the whole family

24 An ISSN family

25 Field 776 with format versions ISSN of this version (print) ISSN of other versions

26 Multiple ISSN Problem ISSN policy: separate ISSN for e-version Some publishers were using single ISSN Some OPACs have separate records; others have single records Failures in OpenURL linking, record merging, de-duping, etc.

27 Revision of the ISSN Standard (ISO 3297)

28 A separate ISSN for each version? A single ISSN to identify all versions?

29 Revised ISSN International Standard ISO 3297: 2007 published August 2007

30 The Revised Standard Affirms policy of separate mediumspecific ISSN Adds new collocating mechanism: linking ISSN (ISSN-L) Catalyst for ISSN User Group Covers all continuing resources, integrating as well as serials

31 Medium-specific Identification ISSN remains at this level Per ISSN Manual: separate ISSN for print, online, CD-ROM, etc. versions Same level prescribed by AACR2 Used for specific product identification library ordering, claiming, check-in subscription agencies, EAN, CCC

32 EAN for a French serial

33 Medium-Neutral Identification/collocation OpenURL resolution regardless of multiple ISSN for manifestations Collocation in ERMS OPAC searching to retrieve all manifestations E-articles, bib records, or ERMS entries where there is no full online version of the serial All situations where identification without regard to medium is desired

34 ISSN-L First-assigned medium-specific ISSN also = ISSN-L * Can be embedded into DOI, URN, OpenURL MARC $l (ISSN-L) MARC $m (cancelled ISSN-L)

35 Made-Up Example: 022 $l ISSN-L

36 Retrospective ISSN-L Designation Entire ISSN register populated with ISSN-L All resources will have an ISSN-L--whether published in one medium or more Ceased and current resources to have ISSN-L Retrospective designation uses lowest ISSN from the cluster linked via 776 field Future (ongoing) designation will use the first-assigned ISSN* ISSN-L cannot be predicted; some situations will be complex *May not always be the lowest in numerical order because of the way ISSN are allocated to ISSN centers

37 Free!!! Tables of Correspondences Coming soon: ISSN International Centre Web site to include two free tables: ISSN to ISSN-L ISSN-L to ISSN

38 Free Tables of Correspondences* ISSN ISSN-L ISSN-L ISSN ISSN ISSN * artist s conception may not be exact

39 CAUTION: If incorrect ISSN are in 022 $a of database records, matches will fail or incorrect ISSN-L will be added

40 Display of ISSN for All Versions Publisher displays on all issues: The Physiologist ISSN (print) ISSN (online) ISSN-L

41 ISSN-L Implementation ISSN Register checking, clean-up Population of ISSN Register with ISSN-L Meetings at ALA Anaheim Launch at IFLA, August 2008 Determination of which centers will selfdesignate ISSN-L Expected implementation before end of 2008

42 Interoperability The ability of two or more systems or components to exchange information and to use the information that has been exchanged. [IEEE 90]

43 Standards are increasingly important in an increasingly non-standard world

44 The Missing Link ISSN System B System A

45 Good ISSN Data Can Help Importing and exporting data to and from various sources (PAMS, A&I services) Migrating to new systems Data Exchange, ONIX transactions Database management: merging, matching ERMS ILS, OPAC De-duplication Linking OpenURL

54 Services can only be as good as the data that supports the service!

55 Shows print and online, like ISSN Portal

56 ISSN can be used to link from OPAC to other sources Information not in OPAC record

58 Linking Publishers & Libraries Publisher metadata NSDP Draft catalog record

59 ISSN Registration: Publisher provides metadata via Web ISSN application form NSDP uses publisher metadata as basic descriptive metadata Cataloger edits and augments metadata with ISSN elements, controlled headings

64 Benefits Exchange of clean metadata: publisher gets authoritative ISSN; ISSN record based on metadata from source Creation of baseline OPAC records, for enhancement with controlled headings Closer ties between publishers and libraries Potential metadata exchange partners: A&I services, OpenURL knowledge bases, vendors, PAMS
