The Multimedia Content Description Interface (MPEG-7) is an ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) standard developed by MPEG (Moving Picture Experts Group). MPEG-7 aims to create a standard for describing the multimedia content data that will support some degree of interpretation of the information’s meaning, which can be passed onto, or accessed by, a device or a computer code. MPEG-7 is not aimed at any one application in particular; rather, the elements that MPEG-7 standardizes shall support as broad a range of applications as possible.
Only some elements from the Multimedia Description Schemes (MDS) part of MPEG-7 which we think are relevant for language resources are described in the overview.
