3.16 Use History
The Use History (M71) element lists each use (retrieval) of a record. The intent is that this element will document all accesses of the record. The recordkeeping system may log both accesses to the content of a record and accesses to the metadata associated with the record. Use histories are likely to be extremely large and not all systems will retain this history.
A use history comprises a sequence of events which are represented by Use (M72) subelements. Each Use (M72) documents one access.
Figure 14. Subelements of the Use History element.
The subelements of Use History are:
- Use (M72). Each Use subelement documents an access. Each use comprises three pieces of information: Use Date/Time (M73), Use Type (M74), and Use Description (M75).
- Use Date/Time (M73). The date and time the access occurred. This should not be overspecified; for example if the date is known, but not the time, the Use Date/Time subelement should not contain the time.
- Use Type (M74). The type of use. The NAA Standard has an extensive list of use types which are duplicated in the VERS Standard, however, recordkeeping systems would normally use only 'Metadata Accessed' or 'Content Accessed'. It should be noted that most electronic systems cannot distinguish between Content Accessed, Copied, Downloaded, Screen Dumped, and Viewed. In all of these cases a copy of the record is downloaded to a computer for display; what happens on that computer subsequently cannot be determined by the recordkeeping system.
- Use Description (M75). A textual description of the access. This would normally include the user that accessed the record and details of the access (e.g. the computer that requested the access).
An example of a Use History element follows:
<naa:UseHistory>
<vers:Use>
<naa:UseDateTime>2003-03-30T05:02:38-10:00</naa:UseDateTime>
<naa:UseType>Content Accessed</naa:UseType>
<naa:UseDescription>Accessed by John Smith (j.smith@dpc.vic.gov.au) from 180.205.76.43. </naa:UseDescription>
</vers:Use>
</naa:UseHistory>
