Alan Orth	884e8f970d	csv_metadata_quality/check.py: Simplify AGROVOC check ... I recycled this code from a separate agrovoc-lookup.py script that checks lines in a text file to see if they are valid AGROVOC terms or not. There I was concerned about skipping comments or something I think, but we don't need to check that here. We simply check the term that is in the field and inform the user if it's valid or not.	2019-08-21 16:35:29 +03:00
Alan Orth	ed5612fbcf	Add column name to output in date checks ... This makes it easier to understand where the error is in case a CSV has multiple date fields, for example: Missing date (dc.date.issued). Missing date (dc.date.issued[]). If you have 126 items and you get 126 "Missing date" messages then it's likely that 100 of the items have dates in one field, and the others have dates in other field.	2019-08-21 15:31:12 +03:00
Alan Orth	13d5221378	csv_metadata_quality/check.py: Fix test for False	2019-08-10 23:52:53 +03:00
Alan Orth	9ce7dc6716	Add check for uncommon filenames ... Generally we want people to upload documents in accessible formats like PDF, Word, Excel, and PowerPoint. This check warns if a file is using an uncommon extension.	2019-08-10 23:41:16 +03:00
Alan Orth	62fea95087	Improve suspicious character detection ... Now it will print just the part of the metadata value that contains the suspicious character (up to 80 characters, so we don't make the line break on terminals that use 80 character width by default). Also, print the name of the field in which the metadata value is so that it is easier for the user to locate.	2019-08-09 01:25:40 +03:00
Alan Orth	bf876a046a	Rework AGROVOC validation ... AGROVOC validation is now disabled by default, but can be enabled on a field-by-field basis. For example, countries and regions are also present in AGROVOC. Fields with these values can be enabled using the new `--agrovoc-fields` option. I reworked the script output to show the field name when printing an invalid term so that the user knows in which field the term is.	2019-08-01 23:51:58 +03:00
Alan Orth	3c798fb504	Use pycountry instead of iso-639 for languages ... The latter is a fork that hasn't been updated since 2016 and the original still seems to be well maintained, with recent database updates as well as tests for Python 3.7. Also, pycountry supports ISO 3166-2 (administrative zones), which we could eventually use for sub regions.	2019-07-30 16:39:26 +03:00
Alan Orth	4e3511cd55	csv_metadata_quality/check.py: Fix AGROVOC lookup ... We actually only need to see if there are more than zero matches because a term like "Nigeria" will match in English, Spanish, etc, whereas terms that *really* don't match will have zero results.	2019-07-30 14:51:44 +03:00
Alan Orth	1f65a28307	Add support for validating subjects against AGROVOC ... Checks values in the dc.subject or dcterms.subject field against the AGROVOC REST API hosted by FAO. Code borrowed from agrovoc-lookup.py. See: http://agrovoc.uniroma2.it/agrovoc/agrovoc/en/ See: https://github.com/ilri/DSpace/blob/5_x-prod/agrovoc-lookup.py	2019-07-30 00:30:31 +03:00
Alan Orth	a36454a3ac	Add support for validating languages ... Will validate against ISO 639-2 or ISO 639-3 depending on how long the language field is. Otherwise will return that the language is invalid. Does not currently have any support for generic values like "Other".	2019-07-29 18:59:42 +03:00
Alan Orth	d7888d59a8	csv_metadata_quality/check.py: Return date even if it is invalid ... Otherwise it is missing from the final CSV and then we can't even fix it. :)	2019-07-29 17:40:14 +03:00
Alan Orth	fa4fa3491b	Add check for "suspicious" characters ... These standalone characters often indicate issues with encoding or copy/paste in languages with accents like French and Spanish. For example: foreˆt should be forêt. It is not possible to fix these issues automatically, but this will print a warning so you can notify the owner of the data.	2019-07-29 17:08:49 +03:00
Alan Orth	42920e9c7c	Test Python regular expression matches directly ... Match objects always have a boolean value of True. See: https://docs.python.org/3.7/library/re.html	2019-07-29 16:16:30 +03:00
Alan Orth	87b1997051	Fix whitespace errors found by flake8	2019-07-28 17:47:28 +03:00
Alan Orth	196bb434fa	Add date validation ... I'm only concerned with validating issue dates here. In DSpace they are generally always YYYY, YYY-MM, or YYYY-MM-DD (though in theory they could be any valid ISO8601 format). This also checks for cases where the date is missing and where the metadata has specified multiple dates like "1990||1991", as this is valid, but there is no practical value for it in our system.	2019-07-28 16:11:36 +03:00
Alan Orth	3cf9f9452b	csv_metadata_quality/check.py: Always return field ... We always need to return the field back so apply doesn't set it to null when creating the new data frame.	2019-07-27 01:28:08 +03:00
Alan Orth	aaf3537ba4	Add check for invalid multi-value separators	2019-07-26 23:48:24 +03:00
Alan Orth	02f9d8a736	csv_metadata_quality/check.py: Add check for missing isbn values	2019-07-26 23:45:18 +03:00
