This is a collection of command line tools and a web service written
in Go for working with EPrints 3.3.x EPrint XML, the EPrint REST API and
directly with the EPrints MySQL repository database(s). It is used by
Caltech Library to render our https://feeds.library.caltech.edu website as well as for
migrating content into a new repository system. Some of the command line
tools maybe of more generatl interest while others are specific to
Caltech Library’s needs. Much of the test code presumes access to our
repositories so is specific to our needs.
Go base code
The programs:
- eputil is a command line utility for
interacting (e.g. harvesting) JSON and XML from EPrints’ REST API
- minimal configuration (because it does so much less!)
- epfmt is a command line utility to pretty
print EPrints XML and convert to/from JSON including a simplified JSON
inspired by DataCite and Invenion 3
- doi2eprintxml is a command line
program for turning metadata harvested from CrossRef and DataCite into
an EPrint XML document based on one or more supplied DOI
- ep3apid is a Unix style web service for
interacting with an EPrint repository via a localhost proxy. It includes
the ability to get restricted key lists as well as retrieve a simplified
JSON record representing an EPrints record
- ep3harvester is an EPrints 3.x
metadata harvesting tool working at the MySQL 8 level for EPrints
content. It harvests the contents into a MySQL 8 database, one table per
eprints repository storing the harvested metadata in JSON columns. This
tool can also harvest CSV files with information for people and groups
referenced in the EPrints repositories.
- ep3genfeeds is used to genate the
JSON documents that drive our feeds website.
- ep3datasets is a tool to generate
dataset
collections from previously harvested EPrints repositories
Use cases
Two primary use cases have driven development of EPrinttools
- Reusing the metadata and content in our EPrints 3.3.16 repositories
(see Caltech Library
Feeds
- Populating our EPrints repository from standardize data sources (see
Acacia
Project).
- py_dataset, This
Python module provides access to dataset collections which we use as
intermediate storage for JSON documents and related attachments.
- AMES, The
eprintools command line programs have been made available to Python via
the AMES project. This include support for both read and write to
EPrints repository systems.
