In this report strategies are outlined how relevant metadata for the digital preservation of
architectural data and related external vocabularies can be structured and stored. Related
requirements are identified in WP7, further specified in WP2 and documented in the
deliverables D 2.2.1, D.2.2.2, D.2.2.3 (Requirements documents) and D.7.7.1. Metadata
for data identified relevant within the scope of the DURAARK project will be captured
in OWL/RDF metadata schemas that re-use existing and recognized metadata standards
and only extend them where deemed necessary. The proposed domain-specific metadata
structures cover three main aspects:
Descriptive metadata that stores domain-specific summaries and classification information
of buildings as an intellectual entity type in a LTP system.
Technical metadata that captures information about Building Information Models
(BIM’s) and point cloud models which are the two main representation forms
of buildings the DURAARK project focuses on.
Linked Data metadata that captures information about the vocabularies and datasets
that are used for the semantic enrichment of building models. These are stored
separately alongside the individual building model Information Packages (IP) in the
archive in a Semantic Digital Archive (SDA) for the storage and a Semantic
Digital Observatory (SDO) for the processing of such volatile, evolving data.
The use of this metadata from IFC models and inference methods are described in generic
vendor-neutral terms and exemplified as an extension implementation to the existing
archival system. The suggested reuse of existing schemas and vocabularies is illustrated
in a number of use cases in section 4.
In the appendices of this document complete listings of the respective vocabularies and
schemas are provided.
The results of this document have been created in collaboration with the work and
deliverables in other work packages and specifically with work packages 2 and 7
