Metadata can be stored either internally, [108] in the same file or structure as the data (this is also called embedded metadata), or externally, in a separate file or field from the described data. A data repository typically stores the metadata detached from the data but can be designed to support embedded metadata approaches.

[ 2 ] [ 3 ] [ 4 ] It is “structured information that describes, explains, locates, or otherwise makes it easier to retrieve, use or manage an information resource”, especially in a distributed network environment like for example the internet or an organization.

A .inf file is used to store this metadata in text format, stored in a file with the same base filename, e.g. Menu and Menu.inf, Build.src and Build.src.inf. JPEG + WAV Some digital cameras allow for voice/audio annotations with photos. These are then stored as WAV audio files alongside the JPEG photo file, with the same base filename. PDF ...

The ISO/IEC 11179 model is a result of two principles of semantic theory, combined with basic principles of data modelling. The first principle from semantic theory is the thesaurus type relation between wider and more narrow (or specific) concepts, e.g. the wide concept "income" has a relation to the more narrow concept "net income".
This thesis explores the concept of Web Database Development using Active Server Pages (ASP) and Java Server Pages (JSP). These are among the leading technologies in the web database development. The focus of this thesis was to analyze and compare the ASP and JSP technologies, exposing their capabilities, limitations, and differences between them.
