serializeToBagIt | R Documentation |
The BagIt packaging format https://tools.ietf.org/html/draft-kunze-bagit-08 is used to prepare an archive file that contains the contents of a DataPackage.
serializeToBagIt(x, ...) ## S4 method for signature 'DataPackage' serializeToBagIt( x, mapId = NA_character_, syntaxName = NA_character_, namespaces = data.frame(), mimeType = NA_character_, syntaxURI = NA_character_, resolveURI = NA_character_, creator = NA_character_, ... )
x |
A DataPackage object |
... |
Additional arguments |
mapId |
A unique identifier for the package resource map. If not specified, one will be automatically generated. |
syntaxName |
The name of the syntax to use for the resource map serialization, defaults to "rdfxml" |
namespaces |
An optional data frame containing one or more namespaces and their associated prefix for the resource map serialization. |
mimeType |
The mimetype for the resource map serialization, defaults to "application/rdf+xml". |
syntaxURI |
An optional string specifying the URI for the resource map serialization. |
resolveURI |
A character string containing a URI to prepend to datapackage identifiers for the resource map. |
creator |
A |
A BagIt Archive File is created by copying each member of a DataPackage, and preparing files that describe the files in the archive, including information about the size of the files and a checksum for each file. An OAI-ORE resource map is automatically created and added to the archive. These metadata files and the data files are then packaged into a single zip file.
The file name that contains the BagIt zip archive. Recursively determines the name for a science metadata object. The base file name (eml, datacite, science-metadata, etc) should stay the same. Call the method with the base name and the number of existing files to start with. This is most likely 0. If there's a count defined, add it to the end of the file in () Then call the method again with count += 1 Eventually a free file name will be found, and then the function returns that name
