Best Practices for Publishing, Retrieving, and Using Spatial Data on the Web

Data owners are creating an ever richer set of information resources online, and these are being used for more and more applications. With the rapid growth of connected embedded devices, GPS-enabled mobile devices, and various organizations that publish their location-based data (i.e., weather and traffic services), maps and geographical and spatial information (i.e., GIS and open maps), spatial data on the Web is becoming ubiquitous and voluminous. However, the heterogeneity of the available spatial data, as well as some challenges related to spatial data in particular make it difficult for data users, web applications and services to discover, interpret and use the information in large and distributed web systems. This paper summarizes some of the efforts that have been undertaken in the joint W3C/OGC Working Group on Spatial Data on the Web, in particular the effort to describe the best practices for publishing spatial data on the Web. This paper presents the set of principles that guide the selection of these best practices, describes best practices that are employed to enable publishing, discovery and retrieving (querying) this type of data on the Web, and identifies some areas where a best practice has not yet emerged

Researching the ethical dimensions of mobile, ubiquitous,and immersive technology enhanced learning (MUITEL) in informal settings: a thematic review and dialogue

In this paper we examine the ethical dimensions of researching the mobile, ubiquitous and immersive dimensions of technology enhanced learning (MUITEL), with a particular focus on learning in informal settings. We begin with an analysis of the interactions between mobile, ubiquitous and immersive technologies and the wider context of the digital economy. In this analysis we identify social, economic and educational developments that blur boundaries: between the individual and the consumer, between the formal and the informal, between education and other forms of learning. This leads to a complex array of possibilities for learning designs, and an equally complex array of ethical dimensions and challenges. We then examine the recent literature on the ethical dimensions of TEL research, and identify key trends, ethical dilemmas, and issues for researchers investigating MUITEL in informal educational settings. We then present a summary of research dialogue between the authors (as TEL researchers) to illuminate these MUITEL research challenges, indicating new trends in ethical procedure that may offer inspiration for other researchers. We conclude with an outline, derived from the foregoing analysis, of ways in which ethical guidelines and processes can be developed by researchers - through interacting with participants and other professionals. We conclude that ethical issues need to remain as open questions and be revisited as part of research practices. Because technologies and relationships develop, reassessments will always be required in the light of new understandings. We hope this analysis will motivate and support continued reflection and discussion about how to conduct ethically committed MUITEL research

Seeing Polycentrically: Examining Governance Situations Using a Polycentricity Lens

Because many types of governance can be polycentric, an observer faces a challenge in trying to identify and understand polycentric governance in actual settings. This chapter adopts the perspective of thinking about polycentricity as a lens through which to view governance situations. We take an inquiry approach, considering how one might determine whether and in what ways a given governance situation demonstrates the characteristics of polycentric governance. We proceed through a series of questions an observer could pose as part of 'seeing polycentrically', i.e., looking at the aspects and dimensions of polycentric governance introduced in Stephan, Marshall, and McGinnis as a way of building an understanding of a governance situation. We attempt to describe why these queries are important and how posing and answering these questions helps in examining and understanding the situation. We close the chapter by considering the challenges of assessing the operation of polycentric governance arrangements
