An XML Schema designed for expressing technical metadata for digital still images
Technical Metadata for Digital Still Images - (NISO Z39.87 Data Dictionary)
MIX: Image width, Color space, color profile, Scanner metadata, Digital camera settings
Preservation Metadata/Premis (information about actions on object, on even, on technical environment)

LEVEL OF
MARK UP
Material types books , serials, newspaoers, audio, projects
Granularity - different level of structural mark up
- i.e. article, illustration, poem
Granularity - all material types: pages, footnotes, running title, tables, advertisemnts, image (captions and categories )
Labour intensive
Phased approach in production
Crowd sourcing

METS profiles for different material types
• monographs, serials, newspapers, audio…
Export files :
JPEG2000, lossless, PDF, OCR TXT as ALTO XML, JPEG (150dpi), METSXML and
MARCXML
METS container or wrapper provides a SIP package for delivery and exchange of digital objects accross systems that is OAI-PMH compliant. Wraps descriptive, administrative and structural metadata + PREMIS.
• MODS and MARCXML for descriptive and bibliographical metadata
(http://www.loc.gov/standards/mods/)
( http://www.loc.gov/standards/marcxml/ )
• MIX for image technical metadata ( http://www.loc.gov/standards/mix/ )
• PREMIS for preservation metadata ( http://www.loc.gov/standards/premis/ )

Content and context as part of digitisation processes…
OCR Correction
Automatic and semiautomatic proccess for data extraction …
Distributed work processes i.e. for:
• Mark up level
• OCR correction
• Controlled annotation
• Social tagging
