Create script to standardize OCLC identifier values and remove duplicates

Create script to identify OCLC identifiers by identifier type and normalize values as following:

• Retain (OCoLC)

  • If prefix of 'ocn' or 'ocm' appear, they should be removed

  • If leading zeros appear, they should be removed

  • EXAMPLE: value of OCLC identifier - (OCoLC)ocm123456 should result in (OCoLC)123456

• If duplicates exist after normalization, they should be de-duplicated so that only one of the normalized identifier remain.

• If there's any prefix values that are NOT 'ocm' or 'ocn', the original prefix should remain.

  • Example: OCLC identifier - (OCoLC)tfe0000501056183 should result in (OCoLC)tfe501056183
