Abstract

Metadata are often referred to as data about data. In this respect metadata represent additional information about data, which could otherwise be limited in use without such auxiliary information. Metadata can help to interpret the content of data resources like images and videos, but can also provide support in the management, dissemination, and search and retrieval of data sets through elements like creator, addressees, access rights, security classifications or online-location. An issue arises from the fact that different metadata models are encouraged and used by different communities of interests (COIs). These differences in metadata models hinder the efficient establishment of common, unified metadata across COIs. This paper justifies and recommends a possible solution for a harmonized core metadata model between selected COIs with special focus on the use case "cross-community search and retrieval of geo-related ISR data".
