TITLE: Language-acquisition inspired sustainability modeling for application profiles
ABSTRACT: The ongoing accessibility of digital material is challenged by the constantly changing environment in which it exists. In particular, application profiles are threatened by a number of factors such as loss of context, social change and linguistic change. In this paper, we draw on observations taken from a number of application domains to build simple mathematical models for community growth and change, to explore the impact of community structure on the sustainability model required for application profiles over time. Finally, we discuss the use of similar models in evaluating application profile sustainability in general, and lessons to be drawn for DCMI. |

TITLE: Dublin Core Usage for Describing Documents in Brazilian Government Digital Libraries
ABSTRACT: Digital libraries are increasingly common, being developed by government agencies to disseminate and preserve the documentation produced by its employees. This proposes a challenge in describing this type of documents, dealing official aspects in tools that are originally designed for bibliographic and scientific documents. In this sense, our objective is to verify how digital libraries, linked to the executive, legislative and judiciary Brazilian powers, are describing its documents collections. A study with descriptive and qualitative characteristics reveals the great adoption of DSpace software for creating these digital libraries and Dublin Core to describe the documents, showing DSpace and metadata schema adaptability for nonacademic document types. Thus, one contributes to the discussion on the use of Dublin Core to describe various types of documents on the Internet. |

TITLE: Exploratory Analysis of Metadata Edit Events in the UNT Libraries' Digital Collections
ABSTRACT: This paper presents the results of an exploratory analysis of edit events performed on records in the University of North Texas Libraries' Digital Collections during calendar year 2014. By comparing the amount of time that editors worked on records for certain item types and collections, we were able to isolate different categories of activities ("creating" vs. "editing") and to generalize rough benchmarks for expected editing durations depending on project criteria. |

TITLE: A DDC Visual Interface for Metadata Exploration
ABSTRACT: This paper presents a visualization interface for DDC-enriched metadata collections. Three sets of metadata from three different digital libraries were aggregated and re-indexed. Automatic analysis was performed to assign one or more DDC classes to each individual metadata record. A comprehensive search and exploratory interface was designed and implemented to include dashboard views, localized views, and universe views of DDC and the metadata collections. Finally, an experiment was conducted to test and compare how subjects interacted with different views for metadata search, exploratory and resource discovery. |

TITLE: Evolution of an Application Profile: Advancing Metadata Best Practices through the Dryad Data Repository
ABSTRACT: Dryad is a curated digital archive for data associated with scholarly publications. In an effort to facilitate the discoverability, reusability, and interoperability of archived content, Dryad has implemented a standardized set of metadata elements in the form of a Dublin Core Application Profile (DCAP, hereafter referred to as application profile). This paper examines the evolution of Dryad's application profile from its inception in 2007 to its current practice, version 3.2. We model the relationships between data packages, data files, and publications for each version of the application profile and perform a crosswalk analysis to map equivalent metadata elements across each version. Results covering versions 1.0 to 3.0 show an increase in the number of metadata elements used to describe data objects in Dryad. Results also confirm that Version 3.0, which envisioned separate metadata element sets for data package, data files, and publication metadata, was never fully realized due to constraints in Dryad system architecture. Version 3.1 subsequently reduced the number of metadata elements captured by recombining the publication and data package element sets. This paper documents current practice in the form of version 3.2, and informs a larger effort to update the application profile to meet the needs of Dryad's diverse community of stakeholders and expanding scope. |

TITLE: An Exploratory Analysis of Subject Metadata in the Digital Public Library of America
ABSTRACT: This paper presents results of an exploratory quantitative analysis of subject representation in the large dataset of over 8 million item-level metadata records in the Digital Public Library of America (DPLA) originating from a number of institutions that serve as content or service hubs of DPLA. The findings demonstrate both similarities and differences in subject representation across content and service hub providers. This benchmark study provides empirical data about the distribution of subjects at the hub level (e.g., minimum, maximum, and average number of subjects per record; number of records without subjects; and number of unique subjects) as well as distribution by hub type (content or service hubs), and subjects shared across similar hubs or across the entire aggregation. |

TITLE: A DCAP to Promote Easy-to-Use Data for Multiresolution and Multitemporal Satellite Imagery Analysis
ABSTRACT: Satellite imagery can be exploited for any number of thematic analyses for Earth observationpurposes. Characterization activities using remotely acquired data are currently made complicatedby different limitations relating to, as an example, the meaningful mapping between multi-sensordata or the adding of the geospatial context to satellite information. We argue that describingsatellite images through a metadata application profile may leverage capabilities to promote easy-to-use data for further in-depth thematic analysis. Accordingly, an application profile conformingto the Dublin Core application profile (DCAP) guidelines and dedicated to Earth observations(EO) is being developed. More specifically, we discuss RDF-compliant machine-processableaspects of the EO application profile (EOAP) in terms of the DCMI Description Set Profile(DSP) model. Additionally, a methodological approach to represent a DSP model using UMLprofiling activities is proposed. |

TITLE: Understanding Metadata Needs when Migrating DAMS
ABSTRACT: This study identifies and explores metadata needs associated with migrating to a new Digital Asset Management System (DAMS). Drawing upon results from a 2014 survey, titled "Identifying Motivations for DAMS Migration: A Survey," this paper analyzes survey questions related to metadata, interoperability, and digital preservation. Results indicate three distinct metadata needs for future system development, including support for multiple or all metadata schema, metadata reuse, and digital object identifiers. While some of these needs resemble long-standing conversations in the professional literature, others offer new areas for system development moving forward. |

TITLE: BEAM repository: a proposal for family and personal repository
ABSTRACT: Preservation of cultural heritage has been widely discussed in the last decades. Different groups of people contribute to the production and preservation of cultural heritage through personal and family performance. However, there is a lack of environments specifically prepared to store and organize the resources produced by these groups, resulting in difficulties to access and preserve these materials along the time. The hypothesis is that the digital repository and the structured metadata standards are relevant tools to provide the suitable environment to store, describe, access and preserve family and personal resources. The study herein has a theoretical and applied basis, for it aims to investigate and confirm the hypothesis using theories and applying them. It aims at demonstrating that the digital repositories are relevant for the storage, description, access and preservation of personal and family information. During implementation of the digital repository, DSpace software and Dublin Core standard were used. As a result, the implemented repository showed itself as a viable alternative for storing this information. It is possible to conclude that such a digital repository constitutes a tool that guarantees the preservation, access and sharing of archives, resources and data produced by families and individuals in the digital environment. |

TITLE: Guidance, Please! Towards a Framework for RDF-based Constraint Languages.
ABSTRACT: In the context of the DCMI RDF Application Profile task group and the W3C Data Shapes Working Group solutions for the proper formulation of constraints and validation of RDF data on these constraints are developed. Several approaches and constraint languages exist but there is no clear favorite and none of the languages is able to meet all requirements raised by data practitioners.To support the work, a comprehensive, community-driven database has been created where case studies, use cases, requirements and solutions are collected. Based on this database,we published by today 81 types of constraints that are required by various stakeholders for data applications. We generally use this collection of constraint types to gain a better understanding of the expressiveness of existing solutions and gaps that still need to be filled. Regarding the implementation of constraint languages, we already proposed to use high-level languages to describe the constraints, but map them to SPARQL queries in order to execute the actual validation; we demonstrated this approach for Description Set Profiles.In this paper, we generalize from the experience of implementing Description Set Profiles by introducing an abstraction layer that is able to describe any constraint type in a way that is more or less straight-forwardly transformable to SPARQL queries. It provides a basic terminology and classification system for RDF constraints to foster discussions on RDF validation. We demonstrate that using another layer on top of SPARQL helps to implement validation consistently accross constraint languages and simplifies the actual implementation of new languages. |

TITLE: The Use of Application Profiles and Metadata Schema by Digital Repositories
ABSTRACT: Shows the results of a survey by questionnaire sent to the managers of 2,165 digital repositories registered at the OpenDoar. Its purpose was to identify the existence and the use of application profiles and related metadata schemas. Of this total, 431 questionnaires were filled. The survey enabled the identification of profiles, as well as schemas and metadata elements used for these repositories. According to the results the number of repositories that use or provide application profiles is very low. The Dublin Core remains as the most commonly used metadata schema, followed by the MARC 21, METS and MODS. The dataset that resulted from the survey is openly available at RepositrioUM, the institutional repository of the University of Minho. |

TITLE: Do We Need Application Profiles? Reflections and suggestions from work in DCMI and ISO/IEC
ABSTRACT: In this paper, the authors question the role and naming of "˜application profiles' (APs). It is not a research paper but aims to initiate a discussion that the authors think is pertinent. Both have been involved in the development and use of application profiles for some considerable time. This paper does not provide answers but aims to raise issues for others' consideration. Essentially, the issues show that communities can share work easily through the interchange of APs but suggests that greater precision in their naming would be useful, and they may not always be necessary given current technologies. |

TITLE: A DCAP for the Social and Solidarity Economy
ABSTRACT: This paper presents a Dublin Core Application Profile (DCAP) developed to serve the Social and Solidarity Economy (SSE). SSE organisations work with scarce resources, networking and partnerships appear as a highly relevant way of working, with potential for SSE organisations to gain visibility and attract funding, or even to be able to work at scale. Studies revealed that the SSE community wants to implement interoperability between their Web platforms - to build a global SSE e-marketplace, and also among their Web platforms and external ones. The DCAP-SSE serves this purpose; it was developed based in the Me4MAP, a method for the development of metadata Application Profiles. SSE organisations are submerged in the market economy but they have specificities not taken into account in this economy. The DCAP-SSE integrates not only terms from well-known metadata schemas, Resource Description Framework (RDF) vocabularies or ontologies, in order to enhance interoperability and take advantage of the benefits of the Linked Open Data ecosystem, but also terms from the essglobal RDF vocabulary. This new vocabulary was created to respond exactly to the SSE specific needs. The DCAP-SSE also integrates five new Vocabulary Encoding Schemes to be used with DCAP-SSE properties. This version of DCAP-SSE is a work in progress. Validation work needs to be continued, and new SSE dimensions will probably be integrated in future versions of the DCAP-SSE. Some work of dissemination and of development of support materials needs also to be undertaken. |

TITLE: MOD: Metadata for Ontology Description and Publication
ABSTRACT: Ontology is an important artifact in Semantic Web applications. Today, there is enormous number of ontologies available on the Web. Even then, finding and identifying the right ontology is not that easy. This is because majority of the ontologies are either not described or described with a general purpose metadata vocabulary like, Dublin Core. On the other hand, ontology construction, irrespective of its types (e.g., general ontology, domain ontology, application ontology), is an expensive affair both in terms of human resources and other infrastructural resources. Hence, the ideal situation would be to reuse the existing ontologies to reduce the development effort and cost, and also to improve the quality of the original ontology. In the current work we present an ontology metadata vocabulary, called Ontology Library Metadata (OLM) for describing and publishing the ontologies. To design the vocabulary, we also propose a set of guiding principles and a well-established methodology, which counts real concerns of ontology users and practitioners. |
