Sample Data for ingestion

[afandian]

We have two kinds of test data. The ‘corpus’ data is large but randomly chosen. The regression data is diverse, specific but out of date. Locate metadata that covers a selection of content types to give a reliable cross-section of our features.

Definition of done:

• All of the work types enumerated in documentation. e.g. about 15 types.
• All of the supporting input types.
• For each, there is a good number (e.g. 100) of works that implement relevant features including any quirks.
• Tests parse, with manually verified that they are correctly represented in regression test suite.
