model may become the real mainstream in the future scientific research community. What’s more,
the introduction of free market exchange makes the data market model a plus for data sharing
model selection. While the hinders of such model include the high-tech challenges from the high
specificity of data assets and the difficult negotiation between public funding data production and
added value data trading.
Above all, throughout the overall development of scientific data sharing, model study shall
continue forward. The mainstream data sharing models are bound to complement one another
and jointly promote the scientific research by sharing data within but not limited to those existing
models. Meanwhile, the inherent data sharing path dependence reshapes the real practices
of ideal data sharing model to some extent. Besides, data sharing is inevitably subject to the
existing framework of local culture and customs of research community. The reforms of data
sharing models are more likely to take a gentle way step by step. Facing the current data sharing
model arrangement, if the dominant data sharing model namely the data resources pool model
could absorb more from others according to particular data attributes, open data can make more
progress.

Construction of a unified metadata model for electronic records preservation

Metadata is an essential tool for electronic records management and preservation; it has received
high attention in maintaining the authenticity, integrity, usability of electronic records and
enabling the understanding of information objects. Among the related metadata standards and
guidelines, metadata models, which play the role of “meta-standards”, can provide a basic
framework for both the authorities and the organizations to develop concrete schemes. The most
widely used metadata models in records and archives management field include recordkeeping
metadata conceptual model of ISO 23081, preservation metadata model of PREMIS and technical
environment information model of PRONOM. But none of them initially serves the purpose of
the long-term preservation of electronic records, no matter which metadata model is applied in
records preservation organizations, some kind of refinement, expansion or adjustment is always
needed.
This paper aims at building a unified metadata model for electronic records preservation through
analyzing, comparing and integrating the metadata models of ISO 23081, PREMIS and PRONOM.
As an inclusive solution of the existing standards, this unified model provides a common
conceptual framework for electronic records preservers to formulate metadata application profile
and support metadata reuse between electronic records preservation system and electronic records
