Me4DCAP V0.1

Authors
Malta, Mariana Curado; Baptista, Ana Alice;

Publication

Abstract
This report is framed in a research in progress project that has as goal the development of a method for the development of Dublin Core Application Pro les (Me4DCAP). The development of the rst version of Me4DCAP has been published. This paper describes in detail Me4DCAP V0.1, showing the sources used to justify its design. Me4DCAP was based in a Design Science Research methodological approach. It has as starting point the Singapore framework for Dublin Core Application Pro les (DCAP) and the Rational Uni ed Process; and integrates also knowledge from: (i) software development processes and techniques, focusing on the early stages of the processes that deal with data modeling; and from (ii) the practices of the metadata community concerning DCAP development. Me4DCAP establishes the way through the DCAP development. It establishes when activities must take place, how they interconnect, and which deliverables they will bring about; it also suggests which techniques should be used to build these deliverables.

Abstract
The development and widespread market acceptance of recent technological devices, such as smart phones and tablets, poses new challenges and great opportunities for innovative service designs. In fact these devices no longer merely replicate the same functionalities in different contexts, they can also dynamically interact among themselves when in close proximity. Thus, this is a two-fold challenge for service designers, they must handle the additional points of contact between service providers and their customers independently, and also in combinations. In this paper we present the relevant concepts for designing multi-interface services, and also introduce the concept of dynamic service interfaces. We illustrate these dynamic service interfaces by presenting an application to the design of a new multimedia service. This service makes use of dynamic service interfaces to deliver an improved and innovative customer experience. © 2013 IEEE.

Abstract
The municipal planning and management tasks are generally performed based on text documents or through digital maps provided by geographic information systems (GIS). However, most municipal GIS follow different data models, leading to interoperability problems when there is a need to combine data from different sources. Furthermore, most of the time these tasks are performed in a collaborative way between the municipal technicians, emerging some difficulties in decision making due to the three-dimensional nature of urban space. Thus, this paper describes a methodology which can integrate multiple sources of real data from diverse municipal GIS, in a unified data model based on the CityGML specification. This model is mapped onto an urban ontology oriented for procedural modeling, which, in turn, produces the threedimensional models of the urban environments. The system developed operates in a client-server approach, where the server is responsible for mapping the urban information to the unified data model and the client represents the procedural modeling technology that generates the urban environment in three-dimensional format, allowing users to interact and amplify the existing urban information.

Abstract
This paper presents a solution for geometric manipulation in procedural modeling as an Application Programming Interface (API). This approach intends to enable a more powerful control over the geometric entities by performing selections based on their attributes, similar to picking features in graphical interfaces. This is achieved through the definition of a topological structure, which features a set of properties, such as scope, spatial localization and semantic information. The applicable modeling operations allow a more customized control, as well as successive tracking, which induce a greater, faster and more intuitive approach for geometry generation. This approach still constitutes ongoing work, but has already been successfully applied for the generation of large virtual urban environments.
