I found the point "Library data is expressed primarily as text strings" to be
vague as written, so I have sharpened the point [1] to emphasize the difference
between "unique alphanumeric strings" such as ISBNs and "display-oriented text"
such as "words and names".  Please read the following paragraph and raise a
flag if I have somehow "overinterpreted"...:

    Most information in library data is encoded as display-oriented text
    strings. Some of the resource identifiers used in library data are based on
    unique alphanumeric strings, such as ISBNs for books, but most
    identification is done using words and names.  Some data fields in MARC
    records are coded uniquely, but there is no clear incentive to include
    these in all records as few of them are used for library-system functions.
    Some data fields, such as authority-controlled names and subjects, have
    associated records in separate files, and these records have identifiers
    that could be used to represent those entities in library metadata;
    however, the data formats in current use do not always support inclusion of
    these identifiers in records, so many of today's library systems do not
    properly support their use.

Note "authority-controlled" with hyphen.
