LDLite is a lightweight, open source reporting tool for Okapi-based services. It is part of the Library Data Platform project and provides basic LDP functions without requiring the server to be installed.
To install LDLite or upgrade to the latest version:
$ python -m pip install --upgrade ldlite(On some systems it might be python3 rather than python.)
To extract and transform data:
$ python
>> > import ldlite
>> > ld = ldlite.LDLite()
>> > ld.connect_okapi(url='https://folio-juniper-okapi.dev.folio.org/',
tenant='diku',
user='diku_admin',
password='admin')
>> > db = ld.connect_db()
>> > _ = ld.query(table='g', path='/groups', query='cql.allRecords=1 sortby id')
ldlite: querying: / groups
ldlite: created
tables: g, g__t, g__tcatalog
>> > ld.select(table='g__t') __id | id | desc | expiration_offset_in_days | group

It also serves as a community space for working together on library data problems. To request an invitation, use the Contact page on the LDP website.
