This proof models a common resource-sharing case: a library holds an electronic document, but its internal URL cannot be shared. Authorised resource-sharing staff may save a permitted PDF, supply it for the current request, and explicitly retain it as a reusable delivery copy.
The test record is Building the Future of Open ERM by Ian Ibbotson, dated 13 August 2026. Its MARC 856 retains the internal Google Docs source URL. Public evidence never exposes that URL. The uploaded file is a small, project-authored demonstration PDF; it is not a copy of the internal document.
Requesting agency
The present proof starts with requesting-agency staff creating an ISO 18626 Copy request. It does
not claim a patron-portal request or a delivered notification. Once supplied, the requester reaches
REQ_COMPLETE_RO, protocol state COMPLETE, and phase Completed Fulfilled. No operator action is
offered in this terminal state.
Supplying agency
The first request cannot be supplied automatically: the electronic item has no delivery reference. Staff select the permitted PDF and explicitly choose Retain as a reusable electronic copy.
DocDel creates one reusable resource and the first request-specific offer. ORS records that result,
attaches its stable reference to the exact electronic item, preserves the 856, then sends ISO
CopyCompleted. The supplier reaches SUP_COMPLETE_RO, protocol state COMPLETE, and phase
Completed Fulfilled, again with no terminal operator actions.
Reuse
A later request uses the retained resource automatically. It creates a new patron-specific offer; it does not reuse the first offer or upload the document again.
The runtime evidence contains one DocDel resource and two offers. This separation matters: the resource is reusable, while acceptance and access remain specific to each request.
Patron delivery
The test institution configures this flow as SIMPLE delivery with SECURE document processing,
watermarking, and SIGN+DATE attestation. Those are site policy choices, not product-wide defaults.
The downloaded response was verified as a PDF whose extracted text includes the configured watermark and the demonstration content.
This Save-As model enriches an existing electronic item because the item and its internal source already exist. Scanning a physical item remains deliberately different: it creates a distinct digital Instance and Item with explicit source provenance.
