This article describes how virtual research environments (VREs) offer new opportunities for researchers to analyse open data and to obtain new insights for policy making. Although various VRE-related initiatives are under development, there is a lack of insight into how VREs support collaborative open data analysis by researchers and how this might be improved, ultimately leading to input for policy making to solve societal issues. This article clarifies in which ways VREs support researchers in open data analysis. Seven cases presenting different modes of researcher support for open data analysis were investigated and compared. Four types of support were identified: 1) ‘Figure it out yourself', 2) ‘Leading users by the hand', 3) ‘Training to provide the basics' and 4) ‘Learning from peers'. The author provides recommendations to improve the support of researchers' open data analysis and to subsequently obtain new insights for policy making to solve societal challenges.

Public and private organizations increasingly release their data to gain benefits such as transparency and economic growth. The use of these open data can be supported and stimulated by providing considerable metadata (data about the data), including discovery, contextual and detailed metadata. In this paper we argue that metadata are key enablers for the effective use of Linked Open Data (LOD). We illustrate the potential of metadata by 1) presenting an overview of advantages and disadvantages of metadata derived from literature, 2) presenting metadata requirements for LOD architectures derived from literature, workshops and a questionnaire, 3) describing a LOD metadata architecture that meets the requirements and 4) showing examples of the application of this architecture in the ENGAGE project. The paper shows that using metadata with the appropriate metadata architecture can yield considerable benefits for LOD publication and use, including improving find ability, accessibility, storing, preservation, analysing, comparing, reproducing, finding inconsistencies, correct interpretation, visualizing, linking data, assessing and ranking the quality of data and avoiding unnecessary duplication of data. The Common European Research Information Format (CERIF) can be used to build the metadata architecture and achieve the advantages.

In this chapter I will describe what the CLARIN infrastructure is and how it can be used, with a focus on the Low Countries (and especially the Netherlands) part of the CLARIN infrastructure. I aim to explain how a Humanities researcher can use the CLARIN infrastructure. I describe the basic functionality that CLARIN aims to offer, including searching for data and software, applying software to data, and storing data and software resulting from research.

If we want to share data, the long-term storage of those data in a trustworthy digital archive is an essential condition. Trust is the basis of storing and sharing data. That trust must be present in the various stakeholders involved. Certification of digital archives can make an important contribution to the confidence of these stakeholders in the digital archives. Ten years ago DANS was assigned the task of developing a Seal of Approval for digital data to ensure that archived data can still be found, understood and used in the future. In 2009 this Data Seal of Approval (DSA) was transferred to an international body, the DSA Board, which has managed and further developed the guidelines and the peer review process ever since. The objectives of the DSA are to safeguard data, ensure high quality and guide reliable management of data for the future without requiring implementation of new standards, regulations or heavy investments. The DSA contains 16 guidelines for applying and verifying quality aspects concerning the creation, storage, use and reuse of digital data. Based on feedback from data archives that applied for a DSA and different case studies we have gained some insight into the benefits of DSA. Still, the impact of having the Seal is not easy to measure. Seal holders usually refer to qualitative benefits in the form of increased awareness of the value of their repositories to their communities, funders and publishers. Ten years down the line we can safely state that the Data Seal of Approval has proven its added value. If we try to look five years into the future, what can we expect? There are different developments: a growing interest in DSA among European research infrastructures, the collaboration between DSA and the ISCU World Data System under the umbrella of the RDA (Research Data Alliance) and the European Commission is showing a growing interest in certification services. The success of DSA also provides the challenge to further professionalize the DSA organization in the coming years, this to enable its community to continue to grow.

This article explores the affordances and functionalities of the Dutch CLARIAH research infrastructure – and the integrated video annotation tool – for doing media historical research with digitised audiovisual sources from television archives. The growing importance of digital research infrastructures, archives and tools, has enticed media historians to rethink their research practices more and more in terms of methodological transparency, tool criticism and reflection. Moreover, also questions related to the heuristics and hermeneutics of our scholarly work need to be reconsidered. The article hence sketches the role of digital research infrastructures for the humanities (in the Netherlands), and the use of video annotation in media studies and other research domains. By doing so, the authors reflect on their own specific engagements with the CLARIAH infrastructure and its tools, both as media historians and co-developers. This dual position greatly determines the possibilities and constraints for the various modes of digital scholarship relevant to media history. To exemplify this, two short case studies – based on a pilot project ‘Me and Myself. Tracing First Person in Documentary History in AV-Collections’ (M&M) – show how the authors deployed video annotation to segment interpretative units of interest, rather than opting for units of analysis common in statistical analysis. The deliberate choice to abandon formal modes of moving image annotation and analysis ensued from a delicate interplay between the desired interpretative research goals, and the integration of tool criticism and reflection in the research design. The authors found that due to the formal and stylistic complexity of documentaries, also alternative, hermeneutic research strategies ought to be supported by digital infrastructures and its tools.

In the Netherlands, the archiving and publication of archaeological research data has led to the establishment of the e-Depot for Dutch Archaeology (EDNA) accommodated at DANS. EDNA is a collaboration between DANS and the Cultural Heritage Agency (RCE). DANS is an institute of the Royal Netherlands Academy of Arts and Sciences (KNAW) and the Netherlands Organisation for Scientific Research (NWO). The slogan "Digital archaeology requires a digital memory" was used in 2007 to bring care for digital data to the attention of Dutch archaeologists. The e-depot ensures durable archiving and unlocking of all digital documentation of the archaeological research. By 2014, DANS provides online access via EASY to more than 21,500 archaeological datasets: 18,500 reports and 3,000 large datasets consisting of data of excavations and explorations (photos, GIS, data-tables, drawings). Both the research descriptions and all data can be downloaded. Agreements to this end have been laid down in the quality standard for Dutch archaeology. DANS ensures that access to digital research data keeps improving, through its services and by taking part in national and international projects and networks. By participating in projects such as Odyssee, CARARE, ARIADNE and DARIAH, the options for finding, accessing and re-using archaeological and other data are continuously improving. DANS stimulates cooperation between data producers and users and does research into long-term accessibility. The existing infrastructure of the e-depot for Dutch Archaeology allows for sharing of good practices such as long-term preservation, data organisation and data dissemination for accessibility.
