AllFilesMD Extension Schema AlFilesMD contains technical metadata that describe any digital file. AllFilesMDType: The AllFilesMDType complex type provides general administrative metadata about file groups and/or files extracted from file system or by processing the file itself. It has the following attributes: 1. checksum: information about the checksum of the file; 2. event: datetimes of create, modify, and access of the file i.e. CCYY-MM-DDThh:mm:ss ; 3. encapsulation: type of file packaging such as zip or tar format; 4. owner: owner/administrator of the file; 5. security: type of security used to protect the file; 6. size: size of the file in bytes; 7. use: use of the file e.g. Master, ServiceHigh, ServiceLow, Support, etc... 8. watermark: type of watermark for the file; AllFilesMDType: Complex Type for encapsulating within a single parent element the individual digital archival object elements that describe an object or portion of an object. But note that the individual digital archival object elements that comprise the AllFilesMD schema can be used independently of the digital archival object element and directly under a METS mdSec.dmWrap element. The individual elements that comprise a digital archival object element are documented under their corresponding types. AllFilesMDType has a single attribute, ID (XML ID). checksumType: Complex Type for recording information about the checksum used in a file. checksumType has 2 attributes, ID: (XML ID) FIELDTYPE: qualifier of the type of channel metadata contained in the element. - checksumType: the type of checksum used in the file - checksumValue: the value of the checksum - checksumDateTime: the datetime the checksum was applied, i.e CCYY-MM-DDThh:mm:ss eventType: Complex Type for recording the datetimes of file creation, last modify, and last access events. eventType has 2 attributes, ID: (XML ID) FIELDTYPE: qualifier of the type of datetimes associated with the file. - dateTimeCreate: the datetime the file was created, CCYY-MM-DDThh:mm:ss - dateTimeModify: the datetime the file was last modified, CCYY-MM-DDThh:mm:ss - dateTImeAccess: the datetime the file was last accessed, CCYY-MM-DDThh:mm:ss encapsulationType: Complex Type for recording the type of file packaging used to encapsulate the file. encapsulationType has a single attribute, ID: (XML ID) ownerType: Complex Type for recording the name of the owner/administrator of the file. ownerType has a single attribute, ID: (XML ID) securityType: Complex Type for recording information about the security and encryption used in the file. securityType has a 2 attributes, ID: (XML ID) FIELDTYPE: qualifier of the type of security and encryption associated with the file. - securityPassword - securityEncryptionType - securityEncryptionValue sizeType: Complex Type for recording the size of the item or portion of an item. sizeType has a single attribute, ID (XML ID). useType: Complex Type for recording the use to which the file will be put e.g. Master, Service, etc.... useType has a single attribute, ID: (XML ID) watermarkType: Complex Type for recording the type of watermark used in the file. watermarkType has a single attribute, ID (XML ID).
