Abstract

Metadata descriptions are typically monolithic data structures and their denormalized, text-based nature yields shortcomings such as inconsistencies and heterogeneities. Moreover, fluidity of research environments, coupled with single-tenancy of metadata descriptions, impedes enforcing authority on the related datasets effectively. We propose a novel paradigm for metadata articulation, delegation, that helps solve the aforementioned issues. After elaborating on the requirements to this practice, we present two worked-out implementation examples in the domain of geospatial metadata and discuss its advantages with respect to key issues in this domain; namely, metadata consistency, interoperability, and mitigating semantic heterogeneity. The technique and the supporting software we present are equally applicable to any XML-based metadata schema and application domain.

It should be noted that our methodology generalizes this approach to all metadata fields of any XML metadata schema.

Note that version 2.0 of the SensorML standard addresses this issue via the sensor type construct, where the sensor model is described in a separate document.

Iniatives, such as INSPIRE, represent institutional attempts at formalizing such diversity.

Minimization of attribute itemscope suggests that Microdata never had XML in its application scope. Moreover, the data models provided by schema.org provide serializations also in the RDFa and JSON-LD formats, suggesting that the repository already moved to a finer semantics.
