In linked data a URI identifies the thing. The thing can have labels (even preferred labels) and relationships to other things, but none of these traits *identify* the thing. Steven Folsom | http: //orcid. org/0000 -0003 -3427 -5769 | Harvard Library

PCC Strategic Direction 3 “Existing methods of library authority control are based on constructing unique authorized access points as text strings (literals). This string-based approach works somewhat well in the closed environment of a traditional library catalog, but not in an open environment where data are shared and linked, and so require unique identifiers. The web presents both a challenge and an opportunity for libraries, which are now in a position to take advantage of authorities created outside of the library world, and also to contribute library authority data for use by other communities. ” Steven Folsom | http: //orcid. org/0000 -0003 -3427 -5769 | Harvard Library

Unanswered Questions in MARC Repeatability, and how to perform heading maintenance if $0’s are repeated? • Consideration being given to accommodating various cataloger realities – Access to Authority Records • Single URI per $a, other URIs linked to from Authority/Thing – No access to related Authority Records • Repeated $0 s in Bib per $a Steven Folsom | http: //orcid. org/0000 -0003 -3427 -5769 | Harvard Library

Unanswered Questions in MARC How to capture URIs in order to provide the clearest semantics? (URIs for things vs. URIs for authorities about things) Currently one subfield ($0 or $w) to capture URIs in BIBs per field; current MARC semantics is “record control number”.
