Created by EDItEUR, the Book IndustryCommunication (UK), the Book Industry Study Group (US) ONIX, 2010 8.
- Established 1998, driven bymusic publishersand performers

- timesfor different purposes
- Providesmappingsto other schemes
- Generic metadata structure with dictionary for multimediaIP commerce
- Part 1: commercial and descriptive terms
- Part 2: legal terms
- Unique indecs identification numbers:iids
indecs created by BBC, RIAA, Content ID Forum (Japan) and Federation of European Publishers Cordis, 2001 9.
- OMA established 2002; DRM v 1 released September2002
- Aimed to bethe centre of all mobile application standardization workand to provideinteroperabilityacross
- devices
- geographies
- services providers
- operators
- networks
- Consists of anXML documentspecifying permissions and constraints
- on resource.
- Content distributed withcryptographicprotection: protected content not usable without the associated rights object on a device
OMA DRM created by Open Mobile Alliance (mobile/wireless industry) OMA, 2010 10.
- MPEG established 1988; MPEG-21 DRM launched2002
- Intended to enableall-electroniccreation, trade, delivery and
- consumption of digital multimedia content
- Makes no distinction between types of users : resource providers and
- consumers are considered equal in terms of publishing, delivering and
- consuming resources
- Providesframeworkgoverning how users interact with other users
- where the object of that interaction is a digital item
- Provides both a rights expression language and arights data dictionary
MPEG-21 created by Moving Pictures Experts Group (ISO/IEC) MPEG, 2010 11. Evaluation:ONIX vs. indecs 12.
- Strengths
- Inexpensive common data exchange format
- Efficient and fast
- Little manual intervention needed
- Highly convertible to MARC-21 format
Evaluation:ONIX
- Weaknesses
- Inflexible: Single price information field prohibits setting multiple prices for varying rights
13. Evaluation:indecs
- Strengths
- Interoperable
- Manages IP at every step in the digital supply chain
- Unique identifiers (iids)
- Used by other schemes (MPEG-21)
- Weaknesses
- Extremely generic: may require customization for specific domains/ applications (i.e., legal judgments in different jurisdictions)
