New Term: #detached-header
Action: Addition
Label: Detached Header
Description: Machine-readable metadata for #this, which in general
will be necessary for its scientific use. Examples include FITS
headers distributed without their data blocks or PDS label files.
Relationships: rdfs:subPropertyOf(documentation)
Used-in: <a href="http://voparis-tap-maser.obspm.fr/voyager_pra/epn/dl/dlmeta?ID=VG1-J-PRA-3-RDR-LOWBAND-6SEC-V1.0%3APRA_I.TAB" class="">http://voparis-tap-maser.obspm.fr/voyager_pra/epn/dl/dlmeta?ID=VG1-J-PRA-3-RDR-LOWBAND-6SEC-V1.0%3APRA_I.TAB</a>
Rationale:
In some archives (e.g., NASA/PDS), so-called PDS label files are
associated to each product/document of the archive. In the case of
NASA/PDS data products, the label file contains the required metadata
for decoding the content of #this. It can be looked as a detached
FITS header, stored separately as a plain text file, next to a data
file consisting in a binary stream of bytes. Clients would use the
content type (MIME type) (e.g.: application/x-pds4-label+xml, or
text/x-pds3-label) to enable the processing.</pre><div class=""><br class=""></div></div><div class=""><br class=""></div><div class=""><br class=""></div></body></html>
