eulxml.xmlmap.premis
- PREMIS¶
eulxml.xmlmap
classes for dealing with the PREMIS metadata format for
preservation metadata.
-
class
eulxml.xmlmap.premis.
BasePremis
(node=None, context=None, **kwargs)¶ Base PREMIS class with namespace declaration common to all PREMIS XmlObjects.
Note
This class is intended mostly for internal use, but could be useful when extending or adding additional PREMIS
XmlObject
classes. ThePREMIS_NAMESPACE
is mapped to the prefix p.
-
class
eulxml.xmlmap.premis.
Event
(node=None, context=None, **kwargs)¶ Preliminary
XmlObject
for a PREMIS event.Note
The PREMIS schema requires that elements occur in a specified order, which
eulxml
does not currently handle or manage. As a work-around, when creating a newEvent
from scratch, you should set the following required fields in this order: identifier (id
andad_type
-
date
= <eulxml.xmlmap.fields.StringField>¶ date/time for the event (eventDateTime)
-
detail
= <eulxml.xmlmap.fields.StringField>¶ event detail (eventDetail)
-
id
= <eulxml.xmlmap.fields.StringField>¶ identifier value (eventIdentifier/eventIdentifierValue)
-
id_type
= <eulxml.xmlmap.fields.StringField>¶ identifier type (eventIdentifier/eventIdentifierType)
-
outcome
= <eulxml.xmlmap.fields.StringField>¶ outcome of the event (eventOutcomeInformation/eventOutcome).
Note
In this preliminary implementation, the outcome detail fields are not mapped.
-
type
= <eulxml.xmlmap.fields.StringField>¶ event type (
eventType
)
-
-
class
eulxml.xmlmap.premis.
Object
(node=None, context=None, **kwargs)¶ Preliminary
XmlObject
for a PREMIS object.Curently only includes the minimal required fields.
-
id
= <eulxml.xmlmap.fields.StringField>¶ identifier value (objectIdentifier/objectIdentifierValue)
-
id_type
= <eulxml.xmlmap.fields.StringField>¶ identifier type (objectIdentifier/objectIdentifierType)
-
type
= <eulxml.xmlmap.fields.StringField>¶ type of object (e.g., file, representation, bitstream).
Note
To be schema valid, object types must be in the PREMIS namespace, e.g.:
from eulxml.xmlmap import premis obj = premis.Object() obj.type = "p:file"
-
-
eulxml.xmlmap.premis.
PREMIS_NAMESPACE
= u'info:lc/xmlns/premis-v2'¶ authoritative namespace for PREMIS
-
eulxml.xmlmap.premis.
PREMIS_SCHEMA
= u'http://www.loc.gov/standards/premis/v2/premis-v2-1.xsd'¶ authoritative schema location for PREMIS
-
class
eulxml.xmlmap.premis.
Premis
(*args, **kwargs)¶ Preliminary
XmlObject
for a PREMIS container element that can contain any of the other top-level PREMIS elements.Curently only includes mappings for a single object and list of events.
-
class
eulxml.xmlmap.premis.
PremisRoot
(node=None, context=None, **kwargs)¶ Base class with a schema declaration for any of the root/stand-alone PREMIS elements:
