Creating context for the experiment record: user-defined metadata

Abstract: The drive towards more transparency in research and open data increases the importance of being able to find information and make links to the data. Metadata is an essential ingredient for facilitating discovery and is used in Electronic Laboratory Notebooks to curate experiment data and associated entries with descriptive information and classification labels that can be used for aggregation and identification. Machine-generated metadata helps with facilitating metadata exchange and enabling interoperability, but such metadata is not necessarily in a form friendly for the humans that also need it. A survey of metadata usage in an ELN developed at the University of Southampton indicates many users do not use metadata effectively. Whilst some groups are comfortable with metadata and are able to design a metadata structure that works effectively, many users have no knowledge of where to start to define metadata or even an understanding of what it is and why it is useful. The metadata used within the notebooks is dominated by a few categories, in particular materials, data formats, and instruments. Further investigation is under way to determine whether this pattern of metadata use is common in other online environments, whether users are more likely to create certain types of metadata, and whether lessons can be learned from other environments to encourage metadata use. These findings will contribute to strategies for encouraging and improving metadata use in ELNs such as improved interface designs, user education, standard schema designs, and encouraging collaboration between same-discipline groups to promote consistency and best practices.

A method for integrating multimedia metadata standards and metadata formats with the multimedia metadata ontology

Abstract: The M3O abstracts from the existing metadata standards and formats and provides generic modeling solutions for annotations, decompositions, and provenance of metadata. Being a generic modeling framework, the M3O aims at integrating the existing metadata standards and metadata formats rather than replacing them. This is in particular useful as today's multimedia applications often need to combine and use more than one existing metadata standard or metadata format at the same time. However, applying and specializing the abstract and powerful M3O modeling framework in concrete application domains and integrating it with existing metadata formats and metadata standards is not always straightforward. Thus, we have developed a step-by-step alignment method that describes how to integrate existing multimedia metadata standards and metadata formats with the M3O in order to use them in a concrete application. We demonstrate our alignment method by integrating seven different existing metadata standards and metadata formats with the M3O and describe the experiences made during the integration process.

Method of deriving web service interfaces from form and table metadata

Abstract: A system and method of deriving web service interfaces from form and table metadata is disclosed. The method uses a discovery subsystem to discover services that are available on an application server, retrieves the metadata descriptions of the services on the application server and uses the services discovered and the metadata descriptions to create web services interfaces such that the service is available using web services description language.

The Dublin Core Metadata Registry: Requirements, Implementation, and Experience

Abstract: Metadata registries are an important digital library research area with the promise of satisfying the needs of metadata designers, practitioners, and users. This paper describes the deployment experience involving the Dublin Core Metadata Initiative (DCMI) metadata registry [1] and discusses the opportunities and prospects for metadata registries as part of the evolving Web-based metadata infrastructure. The motivation and architecture of the DCMI registry are discussed. Benefits and beneficiaries are described, as well as barriers to installation and adoption of metadata registry technology. In addition, prospects for further development are discussed.
