Speaker Title Time Abstract Material
B. Cecconi Update on IVOA Vocabularies 14:00   pdf
R. Weigel et al A Standard for Units in Heliophysics 14:15 We describe an effort by representatives from the metadata standards groups of HAPI, SPASE, and ISTP to develop a recommendation for the representation of scientific units in metadata. The recommendation is “Some metadata models in Heliophysics do not have a constraint on unit strings (that is, a standard has not been chosen). We recommend that if a standard is used, it should be VOUnits.” pdf
R. Weigel et al Standardizing Reference Frame Terms in Heliophysics 14:30 We describe an effort by IVOA and Heliophysics representatives to develop a standard for reference frames and reference system terms. The objective of this effort is to provide a proposal for additions to the existing IVOA standard for reference frames. pdf
L. Fretel Generating the Observation Facilities Vocabulary via Multi-Source Data Alignment with Word Embeddings and LLM Validation 14:45 This work focuses on the automatic generation of a controlled vocabulary for observation facilities by aligning data from multiple sources leveraging word embeddings, cosine similarity, and LLM-based validation of entities equivalence. The resulting vocabulary centralizes entity descriptions and acts as a name resolver by linking reference terms to their aliases. pdf
R. Ringuette et al. Increasing FAIR for Metadata Mapped from SPASE 2.x 15:00 Mapping from SPASE metadata to Schema.org and DataCite provide infrastructure to support Open Science, primarily citation and FAIR (Findability, Accessibility, Interoperability, and Reusability). Existing mappings to these structures significantly lack support for these goals, motivating an effort to improve them. We present the final mapping from SPASE to Schema.org with improved support for these goals and alignment with existing standards. Based on this work, we also present a final mapping from SPASE too DataCite. The mapping from SPASE to Schema.org is being implemented in a community open source software package to be incorporated into the SPASE dataset landing page generation pipeline. The mapping from SPASE to DataCite will similarly be implemented in open source software for use by anyone interested. pdf
S. Erard Taxonomy of small bodies of the solar system. 15:15 The expected increase of observations in this field in the coming years calls for a community standard to describe these objets. The current project aims at unifying the existing descriptions. pdf
