Abstract. Provenance access control has been recognized as one of the most important components in an enterprise-level provenance system. However, it has only received little attention in the context of data security research. One important challenge in provenance access control is the lack of an access control language that supports its specific requirements, e.g., the support of both fine-grained policies and personal preferences, and decision aggregation from different applicable policies. In this paper, we propose an access control language tailored to these requirements. 1
Relay-Supporting Archives: Requirements and Progress
- International Journal of Digital Curation
"... We characterize long-term preservation of digital content as an extended relay in time, in which repeated handoffs of information occur independently at every architectural layer: at the physical layer, where bits are handed off between storage systems; at the logical layer, where digital objects ar ..."

We characterize long-term preservation of digital content as an extended relay in time, in which repeated handoffs of information occur independently at every architectural layer: at the physical layer, where bits are handed off between storage systems; at the logical layer, where digital objects are handed off between repository systems; and at the administrative layer, where collections of objects and relationships are handed off between archives, curators, and institutions. We examine current preservation technologies ’ support for these handoffs, note shortcomings, and argue that some modest improvements would result in a “relay-supporting ” preservation infrastructure, one that provides a baseline level of preservation by mitigating the risk of fundamental information loss. Finally, we propose a series of tests to validate a relay-supporting infrastructure, including a second

A Digital Cadastral Data Base (DCDB) is a big investment for a jurisdiction tasked with the administration of land boundaries. In the past, the development of such a database produced no real pay-back on investment until many years, and millions of dollars had been committed. The Land Administration Domain Model (LADM) (ISO-TC211 2012) provides a model of a schema in which a progressive creation and improvement of a DCDB is possible, to allow benefits to be obtained even in the early stages of this effort. It also includes the necessary structure to ensure that a useful historical record of the cadastre can be kept. This paper explores issues to be faced in the development of software based on the LADM, which retains the history of the cadastre, and allows for progressive improvement of the data. The examples of the Netherlands Kadaster and the Queensland (Australia) Department of Natural Resources and Mines are used to evaluate the applicability of the approach.
A Comprehensive Model for Provenance
"... Abstract. In this paper, we propose a provenance model able to represent the provenance of any data object captured at any abstraction layer (workflow/process/OS) and present an abstract schema of the model. The expressive nature of the model makes it potential to be utilized in real world data pro ..."

INFORMATION MODEL FOR ELECTRONIC ARCHIVING OF DOCUMENTS

Archiving means precise marking and storing of a document, as well as its keeping and processing, which supplies the conditions for its quick and efficient finding. There are several ways of archiving the documents: data libraries, microfilms, scanning and electronic archiving. Electronic archiving requires the existance of data base which enables fast approach to pieces of informantion, simple search of the documents in the archive, protection from distroying or missuse, decreasing of the archive space, lower costs of operating as well as full monitoring of the documents. The paper shows information model for electronic archiving using CASE tools as the foundation for data base creation. Key words: electronic archiving, data base, conclusion. 1.
