Abstract [en]

One approach to manage collections is to create data about the things in it. This descriptive data is called metadata, and this term is in this thesis used as a collective noun, i.e no plural form exists. A library is a typical example of an organization that uses metadata, to manage a collection of books. The metadata about a book describes certain attributes of it, for example who the author is. Metadata also provides possibilities for a person to judge if a book is interesting without having to deal with the book itself. The metadata of the things in a collection is a representation of the collection that is easier to deal with than the collection itself. Nowadays metadata is often managed in computer-based systems that enable search possibilities and sorting of search results according to different principles. Metadata can be created both by computers and humans. This thesis will deal with certain aspects of the human activity of creating metadata and includes an explorative study of this activity. The increased amount of public information that is produced is also required to be easily accessible and therefore the situation when metadata is a part of the Semantic Web has been considered an important part of this thesis. This situation is also referred to as the Web of Data or Linked Data.

With the Web of Data, metadata records living in isolation from each other can now be linked together over the web. This will probably change what kind of metadata that is being created, but also how it is being created. This thesis describes the construction and use of a framework called Annotation Profiles, a set of artifacts developed to enable an adaptable metadata creation environment with respect to what metadata that can be created. The main artifact is the Annotation Profile Model (APM), a model that holds enough information for a software application to generate a customized metadata editor from it. An instance of this model is called an annotation profile, that can be seen as a configuration for metadata editors. Changes to what metadata can be edited in a metadata editor can be done without modifying the code of the application. Two code libraries that implement the APM have been developed and have been evaluated both internally within the research group where they were developed, but also externally via interviews with software developers that have used one of the code-libraries. Another artifact presented is a protocol for how RDF metadata can be remotely updated when metadata is edited through a metadata editor. It is also described how the APM opens up possibilities for end user development and this is one of the avenues of pursuit in future research related to the APM.

Abstract [en]

he requirements on learning support from knowledge work differ compared totraditional work. Based on those observations an approach for supporting learning inknowledge work is proposed considering requirements from e-learning as well as fromknowledge management. In addition to traditional e-learning, on-demand e-learning takes thecurrent situation of the knowledge worker into consideration to ensure learning support ofknowledge work is proposed. For using a broad variety of resources in on demand e-learning asingle metadata schema for describing seems not sufficient for every organisation. Therefore,application profiles appear adequate for describing resources used in the proposed approach forarranging knowledge elements. Identifying the knowledge workers current situation a learningneed should be derived and to use it afterwards for selecting and delivering knowledgeelements.

Abstract [en]

Most of today's generic annotation tools for semantic web metadata (RDF) are designed forexperts. People with no or little knowledge about RDF are therefore forced to use simplified andoften domain-specific tools that work with fixed sets of metadata elements. This paper introducesthe Annotation Profile Model as a configuration mechanism from which annotation tools can beautomatically generated. The intention is to encourage metadata- or domain experts to defineannotation profiles according to metadata vocabularies. This will allow end-users oradministrators to select appropriate annotation profiles for the task at hand, and then an editorwill be provided by the underlying system. This paper discusses the design of the AnnotationProfile Model, which consists of a data-capturing part (the Graph Pattern Model) and apresentation part (the Form Template model). An implementation that can generate both web-based and standalone editors is also introduced.

Abstract [en]

The use of RDF on the web is increasing, unfortunately the amount of editing tools suitable for end users without knowledge of technicalities of the language are not so common. We believe that a vital ingredient for the editing tools to flourish is a working remote modification protocol. This will allow editing tools to be developed separately from triple-stores and make them more flexible and reusable. Several initiatives for remote modification exist already but have not gained wide-spread adoption. In this paper we will show that most of them fall short when it comes to edit arbitrary RDF constructs, especially in combination with typical requirements of editing tools. We will first list these requirements, then propose a solution that fulfills them and finally outline an implementation. With this implementation we will also demonstrate how Annotation Profiles, a configuration mechanism for RDF metadata editors, has the additional feature of making modification requests very precise.

Abstract [en]

In 2005 the European Hematology Association developed theEuropean Hematology Curriculum. This was distributed as a printed bookletand the intention was that junior hematologist could use it for personalcompetence development. In the EU-funded project H-net this Curriculum hasbeen adapted into the a web environment by using RDF and placed inside aweb portfolio system. How this is done is further described in this article.Furthermore, the possibilities of reusing the curriculum in ways that was notinitially intended is described, such as describing Learning Resources inside theweb-portfolio system with how they relate to different parts of the curriculum.That way a search for learning resources inside the portfolio by using thecurriculum is enabled. And, since the medical field of hematology is closelyrelated to other medical fields the design of the web-version of the curriculumwas done in a way that builds for possible combination with any othercurriculum in another medical field.

5. The activity of human metadata creation and the Semantic Web

2015 (English)In: International Journal of Metadata, Semantics and Ontologies, ISSN 1744-263X, Vol. 10, no 2, 64-74 p.Article in journal (Refereed) Published
Abstract [en]

This paper presents an explorative study of the human activity of creating metadata, done with the purpose of exploring the practices of this activity and how those can potentially impact the utility of the metadata as it is exposed on a level that enables semantic collaboration, like the Semantic Web. Previous research around human metadata creation seems to indicate that how the activity is carried out has a common core, but is unique in each situation on how it can be improved. The data for this study was gathered through interviews and analyzed using activity theory. The analysis of the data gathered through the interviews indicate that the main objective of the activity is to enable discovery within a collection. Metadata is however created with a community of users in mind, which is sometimes reflected in metadata creation guidelines. These guidelines can in turn impact the discoverability across these communities as metadata is exposed on the Semantic Web.

6. Towards End-User Development for Metadata Creators

(English)Manuscript (preprint) (Other academic)
Abstract [en]

Many organization, like libraries, museums, archives, etc. are dependent on metadata about their resources as a representation of their collection. This paper will present an approach aimed at reducing the need for a developer when constructing the metadata editing tool required for such systems, where the long term goal is to enable end-user development (EUD) for the metadata creators. The approach is still under development, but right now it includes a model and a code-library called RDForms that was designed for developers to quickly set up a form based metadata editor, where the metadata that can be edited is changed through a configuration mechanism. An evaluation on the use of RDForms in the wild is presented that seems to indicate that the developers are the ones also configuring the metadata editor. If the configuration instead could be made by the metadata creators the need for a developer would be even further reduced.
