TRLN Discovery Release Notes

Bug fixes and enhancements for the TRLN Discovery shared catalog are listed at the close of each sprint cycle. The version number of the impacted component is also included if available. Please contact with any questions.

May 2021

  • Catalogers can add standard qualifier text $q exclude to the 020 field to indicate when an ISBN has been shared and should not be pushed out to Syndetics. This corrects an issue where some items were displaying an incorrect book cover provided by Syndetics due to shared ISBN numbers.
  • Marc-to-Argot can now gracefully handle an incomplete 008 field and will no longer fail when this fixed field does not contain the expected number of characters.
  • Updated subject headings remapping file to incorporate terms recently discussed by the TRLN Discovery Metadata Team:
    • freedmen: “Freed people”
    • slave owners: “Enslavers”
    • slave trade: “Trafficking in enslaved persons”
    • slave traders: “Traffickers in enslaved persons”
    • problem children: “Children with behavior disorders”
    • problem youth: “Youth with behavior disorders”
  • Physical media labels are cleared if an item has no holdings. (Marc-to-Argot 0.4.69)
  • We made several improvements to the ingest application including:
    • Facilities for re-running transactions (indexing or ingest) that fall within a certain time period, and (optionally) for restricting them to a particular institution. Form is accessed from the “dashboard” which is available to admin users.
    • Added a “Name Authority” entry on the menu bar and a lookup page for LCNAF IDs.
    • Added an index_date (datetime, single, stored) field to every record as it is indexed. (Spofford 0.6.0)
  • LCNAF data will be updated on a quarterly basis to further support searching variants names.

March 2021

  • Users can search for variants of a name in the LOC authority and return all results associated with that name. This allows users to more easily find all records associated with a person, place, or organization included in the LCNAF. Alternate names might include name changes, various romanizations, and pseudonyms. A URI must be associated with a record in order to search variants names (MarcToArgot 0.4.63)

February 2021

  • When a user searches their local catalog, they will not receive suggestions for items owned by other institutions. (Argon v1.3.20)
  • There is now a spellcheck function that will provide users with a set of suggestions based on the spelling of their query. If their query has no results based on the spelling provided, they will see a prompt asking “Did you mean” followed by a set of suggested queries they can select to see results.
    • Search suggestions only display when there are 5 or fewer results.
    • The suggestions are based on actual words in the catalog index, not a dictionary, so the suggestions themselves may not be spelled correctly but should always produce search results.
    • Some misspelled queries will not produce search suggestions because there are matches in the catalog index.
    • This feature needs to be turned on by each institution in TRLN by updating to Argon v1.3.21 and add this code to the catalog_controller file.
config.default_solr_params = {
spellcheck: 'true'
  • We completed a full reindex to incorporate Solr configuration changes for a new spellchecking feature.

November 2020

  • We needed a way to exclude specific ISBNs, UPCs, and OCLC numbers from Syndetics data matching. If technical services staff come across individual records that need to be excluded form Syndetics matching, they can add “$q = exclude” to any of these fields. The TRLN Discovery Metadata Team was charged with sharing this information out to local technical services departments impacted by this change. We will implement frontend changes in an upcoming release to make this visible to end users. (MarcToArgot 0.4.57)
  • “@” was added to the list of stop words in the Solr configuration to prevent them from being treated as terms by the query parser.
  • Updated subject headings remapping file to incorporate terms recently discussed by the TRLN Discovery Metadata Team. Each institution would need to reprocess records using remapped terms in order for end users to see this change.
  • Solr configuration changes to prepare for planned future work of allowing users to search with variant names listed in the name authority record.
