TEXTMD: LC-AV Text Metadata Extension Schema TEXTMD contains technical metadata that describe a text file. It is based upon metadata defined by LC M/B/RS. TEXTMD contains 4 top-level elements. TEXTMDType: Complex Type for encapsulating within a single parent element the individual digital text archival object elements that describe an object or portion of an object. But note that the individual digital text archival object elements that comprise the TEXTMD schema can be used independently of the schema element and directly under a METS mdSec.dmWrap element. The individual elements that comprise a digital text archival object element are documented under their corresponding types. TEXTMDType has a single attribute, ID (XML ID). file_data: The file_data element is used to describe technical characteristics of a text file. byte_order: This is the simple element which provides a place to store the order of bit significance in a byte from left to right i.e. 0-least-to-most, 1-most-to-least. encoding: This is the simple element which provides a place to store the type of encoding used in an item or portion of an item. format_name: This is the simple element which provides a place to store the n-character name that corresponds to the standard file extension associated with the text format, e.g. html, xml, sgm etc... format_version: This is the simple element which provides a place to store the version of the text format specified in format_name e.g. for format_name="htm" format_version="3.0". markup: This is the simple element which provides a place to store the type of markup language used in an item or portion of an item. security: This is the simple element which provides a place to store the type of security precautions applied to the file e.g. password, encryption, hidden, etc. use: This is the simple element which provides a place to store the use of a digital text file, e.g., Master, Service High, Service Low, Preview. text_info: The text_info element is used to describe text characteristics of an object that not specific to either the physical object or a digital representation. note: This is the simple element which provides a place to store the general information about an item or portion of an item. checksumType: Complex Type for recording the type of checksum used for a digital audio file. checksumType has 1 attribute and 3 elements.
