    D6.6.1 Current state of 3D object digital preservation and gap-analysis report ; DURAARK - Durable Architectural Knowledge ; FP7 - ICT - Digital Preservation
    (2014) Lindlar, Michelle; Saemann, Hedda; Ochmann, Sebastian; Gadiraju, Ujwal; Jonsson, Osten
    This deliverable identifies gaps in existing processes for the digital preservation of 3D objects. The gap analysis is approached through an in-depth analysis of two areas. One area is that of fundamental digital preservation tools and processes regardless of their content type. It describes processes and standards adapted by the global digital preservation community and implemented in archives of varying domains, e.g., archives dealing predominantly with e-publications as well as AV-archives. The second area is that of current existing processes for the digital preservation of 3D objects. It describes aspects and challenges which are uniquely tied to the long-term archiving process of this content-type and lists existing tools and standards. The gaps are identified through a comparison of the content type agnostic and the 3D-specific state of the art descriptions

    D8.4 Dissemination Master Plan and Publicity Material V2 ; DURAARK - Durable Architectural Knowledge ; FP7 - ICT - Digital Preservation
    (2014) Hecher, Martin; Beetz, Jakob; Ochmann, Sebastian; Lindlar, Michelle; Tamke, Martin; Edvardsen, Dag Fjeld; Dietze, Stefan; Jonsson, Östen
    This deliverable (D8.4 Dissemination Master Plan and Publicity Material V2) is an update of D8.2. In order to keep it highly informative, those parts which have already been described in detail in D8.2 are presented in condensed form in this deliverable. The document covers the dissemination plan for the entire remaining period of the DURAARK project. Since this means a forecast for the next two years, not all plans can be presented in a detailed form, as for example dates and agendas for conferences during 2015 are in many cases not published yet. The DURAARK project covers many areas such as digital preservation, semantic enrichment and the comparison of as-planned and as-built state of architectural structures. The outcomes of each area have, so far, mainly been disseminated one by one through subject-specific channels. In the remaining project period these dissemination activities will be complemented by joint consortium activities, where all main outcomes of the project will be presented and discussed at joint events. Special attention has been put on DURAARK´s potential for contribution to standardization. Amongst other efforts this includes the envisaged extension of an IFC file format towards the IFC/A standard, which will provide vast possibilities of semantic enrichment as well as support for efficient 3D point cloud storage. Our assessment is furthermore that DURAARK can substantially contribute towards the development of standard procedures for the preservation of 3D architectural objects.

    D2.2.3 System Architecture & Specification v2.0 ; DURAARK - Durable Architectural Knowledge ; FP7 - ICT - Digital Preservation
    (2014) Beetz, Jakob; Berndt, René; Dietze, Stefan; Edvardsen, Dag Fjeld; Gadiraju, Ujwal; Lindlar, Michelle; Ochmann, Sebastian; Tamke, Martin; Vock, Richard
    This deliverable presents the second iteration on the system architecture of the DURAARK framework. It describes the philosophy, decisions, constraints, justifications, significant elements, and any other overarching aspects of the system that shape the design and implementation. It complements and refines the deliverable D2.2.2 System Architecture & Specification v1.0 from month 6.

    D3.3.2 Ontological Framework for a Semantic Digital Archive ; DURAARK - Durable Architectural Knowledge ; FP7 - ICT - Digital Preservation
    (2014) Beetz, Jakob; Lindlar, Michelle; Dietze, Stefan; Gadiraju, Ujwal; Edvardsen, Dag Field
    In this deliverable, a framework for a Semantic Digital Archive (SDA) for buildings and their components is suggested and described: The organizational framework for the Semantic Digital Archive as well as its methodological and technological enablers are outlined and specified. Conceptual approaches for the creation, maintenance and use of mappings between the building-specific Industry Foundation Classes (IFC) schematic and instance models with established datasets and vocabularies (e.g. the ones offered by the Linked Open Data cloud) are provided. It is shown how such mappings can be used to semantically enrich Building Information Model instances and how such enrichments can be preserved independently of the continuous evolvement of the referenced data sets. In order to track such changes in external data sets and reduce the amount of storage needed in the SDA, the concept of a Semantic Digital Observatory (SDO) is introduced and discussed. Using concrete data sets with a high relevance for the building industry, and in particular the reference vocabulary of then bSDD examples are provided that demonstrate the mechanisms introduced here. During future activities of the DURAARK project, the conceptual approaches introduced here are implemented in software prototypes as a proof of concept solution for the long-term preservation of semantically enriched Building Information Models.

    D3.3.1 Metadata schema extension for archival systems ; DURAARK - Durable Architectural Knowledge ; FP7 - ICT - Digital Preservation
    (2014) Beetz, Jakob; Lindlar, Michelle; Dietze, Stefan; Gadiraju, Ujwal; Long, Qinqin
    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.
