#marc21 — Public Fediverse posts

Today I released version 0.5.0 of marc21-rs. It includes three new commands: `glimpse`, `grep`, and `skosify`. The `skosify` command is just the beginning and will be expanded with additional features in the coming weeks. Stay tuned.

Just released version 0.1.0 (pre-alpha) of polars-marc21 — a polars io plugin for reading MARC21 files. It is based on the MARC21 parser and the query engine from marc21-rs.

I would appreciate any feedback, new ideas, or reports of errors.

I just released version 0.3.0 of marc21-rs. This version includes five new commands: describe, dedup, partition, frequency, and—most importantly—select.

I would appreciate any feedback, new ideas, or reports of errors.

Today, I released version 0.2.0 of a new tool that processes MARC-21 records. It focuses on efficient processing of records and tabulating data for integration into data science or data engineering applications. Feedback and new ideas are very welcome.

Compartimos una reseña-entrevista inaugurando un nuevo formato de publicación en RIBES. En este caso, hablamos con Alicia Sánchez Díez sobre su "Cartilla para catalogar", publicada en 2024:

https://doi.org/10.5209/RIBE.105547

Alicia comenta sobre los FRBR, BIBFRAME, RDA, MARC 21.., y reflexiona sobre la necesidad de materiales docentes actualizados y comprensibles, todo en un contexto muy cercano charlando con @anrodrig y @lrp

-EPUB: https://revistas.ucm.es/index.php/RIBE/article/view/105547/4564456574285

Tal vez esta reseña-entrevista anime a más gente a mandar nuevos trabajos de este tipo a RIBES.

Dear #RStats and #Python users, I am struggling to rectangle, i.e. put in a tabular form, a #Marc21 #xml file. What do you suggest for handling #BibliographicData in this format? I tend to end up with tables where several entries are a list of subfields. Thanks!

BIBFRAME Must Die
by Jeff Edmunds

👉 October 15, 2023 marks the 21st anniversary of Roy Tennant's article "MARC Must Die." With a nod to #MARC21, this article argues that #BIBFRAME is not the way forward for bibliographic description and offers five reasons why.

Writing a document for how we map the data from a MARC-21 record to a Solr document that is indexed and stored in the backend Apache Solr datastore. Having to explain the difference in an indexed field vs a stored field. Having to explain how copy fields work, why they are used, and what stemming is.

I just want to write some code :(

Hm, das klingt im ersten Moment überraschend überzeugend. Daten werden durch Kontext zu Information in Form von #Metadaten, also etwa durch Kategorisierung in ein #Datenmodell oder ein Format wie #MARC21 - oder?

Welcher #Informationswissenschaft 'ler erklärt uns das genau?

Heute hat Péter Király @kiru an der #ÖNB über sein Tool "QA catalogue" zur Analyse von bibliographischen #Metadaten gesprochen.
Das gefällt mir: Es gibt in der Browser-Ansicht für die #MARC21-Daten eine numerische Darstellung und eine weitere "for humans" 😆

Version v1.1.0 of marcli is now available (https://github.com/hectorcorrea/marcli) and it includes a new parameter `-matchFields` to limit what fields are searched in when using `-match`

```
marcli -file marc-file.xml -match="Airline" -matchFields=650
```

Big thanks to @phette23 for making it available via Homebrew as well.

Impression from #swib22 so far: #BIBFRAME is actually becoming reality, migration from #MARC21 or other formats has finally begun. The end goal, however is still moving, as bibframe does not cover all requirements
