We can define metadata as “information about information”, and a LOM is a metadata about a learning object that can refer to multimedia or digital educational resources. Sets of metadata are used to identify and meaningfully describe characteristics relevant to these resources, for example, the learning resource type, the intended end user, difficulty level, educational goal, and so forth. The Learning Technology Standards Committee (LTSC) give rise to the IEEE LOM (Learning Object Metadata) 1484.12.1-2002 standard of educational metadata.

Abstract
The Web is going to produce a revolution in learning and teaching: the debate on the role of ICT in educational processes leads to a reconsideration of how we deal with information and knowledge. The widespread use in educational contexts is also due to the ease with which learning resources can be retrieved and shared: for example, the recent introduction of learning objects means that the contents which reside in different e-learning platforms is easy to find and access. But knowledge is also deeply embedded in millions of Web pages. Nonetheless, searching for information on the Web is not a simple task and the great number of documents found using search engines, such as Google, is beyond the human cognitive capacity to deal with this information overflow. Teaching information literacy skills or stimulating collaborative information filtering that supports the discovery of resources in a way that is responsive to the context of users may help, but there is a need for more efficient cognitive tools to search, organize, and discuss information in order to codify it in shared knowledge structures.
