Initial Brief

[jeffnm]

Goal

The goal is to have a tool that can take a list of OCLC numbers (like https://github.com/wc-library/lastCopyStateChecker) and return a list of OCLC numbers that do not meet the minimum encoding level.

Background Info and API

The encoding levels are described here: http://www.oclc.org/bibformats/en/fixedfield/elvl.html I don't yet know what we consider the minimum levels we can accept.

The api I'm suggesting to use for this is here: https://platform.worldcat.org/api-explorer/apis/wcapi/Bib/Read

We'll want to have the API key stored separately from this repository, so please do not hard code it or include it in the any of the git tracking - I can provide it separately.

Suggestions

• The bib record comes in MARC-XML (MARC is a library standard)
• There are MARC parsing libraries, such as http://pear.php.net/manual/en/package.fileformats.file-marc.php but I'm not sure we want to use them. Let me know if it's needed for this project. I don't know how well maintained the PHP one is, so pymarc or something like that may be better, if we really need to use something other than straight PHP.
• I'd like to let the end user customize what encoding levels they are looking for out of their list of OCLC numbers.

Further comments

I'll add any additional information as I get it, but feel free to add questions, comments, or your own notes that might be useful in the future.

Target Level

The primary target level is 3

I still want the end user to be able to choose the encoding level(s) they are interested in for a particular run. We should also consider displaying the encoding level per record in the results.

Additional Clarifications

1. There should be a way to copy and paste OCLC's into the system.
2. We want to include the letter codes as well as the numerical ones.
3. We want to use a multi-select box for the encoding levels so that the user can choose exactly which levels they want to retrieve.
