Table 1 Different methods for using standards-based metadata to directly retrieve data files from a digital repository

From: Standards-based metadata procedures for retrieving data for display or mining utilizing persistent (data-DOI) identifiers

Entry URL or action Function
1 http://doi.org/10042/32205?locatt=id:5 Using the locatt (location attribute) features to modify handle resolution based on the sequence identifier
2 http://doi.org/10042/32205?locatt=filename:MOPAC-PM7.out Using the locatt (location attribute) features to modify handle resolution based on the filename
3 http://doi.org/10042/32205?locatt=mimetype:chemical/x-mopac-output Using the locatt (location attribute) features to modify handle resolution based on the MIME type
4 onclick=“handle_jmol(‘10042/32205’)” Modifying handle resolution by processing the handle response using a JavaScript event based on the handle_jmol script [28], with the default selection set to the media type: chemical/x-cml
5 http://data.datacite.org/chemical/x-cml/10.14469/ch/26199 Using the DataCite metadata store to specify a media type, allowing a direct URL to this data to be passed for display
6 onclick=“datacite_jmol(‘10.14469/ch/26199’)” Displaying a list of available files using a JavaScript event based on the datacite_jmol script [28], allowing the user to select one
7 onclick=“datacite_jmol(‘10.14469/ch/26199?chemical/x-cml’)” Selection by MIME-type with no user intervention using a JavaScript event based on the datacite_jmol script [28]
8 onclick=“datacite_jmol(‘10.14469/ch/26199?PM7.xml’)” Selection by Filename with no user intervention using a JavaScript event based on the datacite_jmol script [28]
9 http://doi.org/10042/32205?noredirect Determining the redirector for a specified DOI and the 10320/loc records (if any) for that entry
10 1. http://data.datacite.org/10.14469/ch/26199 (DSpace-SPECTRa) [9] Determining the metadata records for a specified DOI
2. http://data.datacite.org/10.6084/m9.figshare.1270384 (Figshare) [32]
3. http://data.datacite.org/10.5517/CC11TJ7M (CCDC) [35]
