Abstract

The metadata system designed and implemented for the German National Educational Panel Study (NEPS) has proven to be a valuable tool to automate data management and documentation for dozens of NEPS studies throughout the past years. Recently, more large-scale studies being conducted at the LIfBi besides NEPS. This has been supported by enhancing the NEPS metadata structure in two ways: (1) By extending the scope of the metadata to central study parameters documenting the field work procedures other study elements for internal purposes, linking these elements to the metadata infrastructures; and (2) by enabling the metadata system to hold information about study projects different form NEPS, whilst fostering metadata reuse between the projects. After a quick introduction to the NEPS metadata system's structure in a nutshell, the presentation will sum up its use for automated documentation and data processing. Afterwards, it will give insights into the process of extending the system for use by other projects. In an outlook, there is room to discuss this practice of opening a “proprietary” (i.e. custom-tailored, not standards-based) metadata system, and the implications for (meta)data sharing in a broader community.
