The topic of this master's thesis is a comparison of web Rapid Application Development frameworks Ruby on Rails and Spring Roo. The paper focuses on creating extensive overview of pros and cons of the subjected tools from the web developer's point of view to enhance his awareness about the subject, also to come up with new questions for further analysis or even convince him to use one of the frameworks in the real projects. Firstly, the paper contains a theoretical overview of the common conceptions for better understanding of the following parts and then specific principles for each of the selected frameworks. Secondly, there is a practical part. On one hand it demonstrates the implementation of a reference application using both platforms to illustrate the practical distinctions. On the other hand, it also contains an overall comparison based on the defined methodology. Altogether, it should form a comprehensive comparison of the selected frameworks for web developers interested in Ruby and Java platforms.

Rephotography has been a popular research topic in the photography field for a long time. The purpose of rephotography itself is to repeatedly take photographs of the same scene at a different time. As a result, the sequence of rephotographs with the reference, often historical, the picture provides a compelling visualization of the evolution of the subject or capture its changes in time. However, the act of rephotography is difficult for the rephotographers as they have to cope with the ambiguous motions in six degrees of freedom and with the changes of the subject itself or its surrounding environment.        This thesis aims to create a mobile application that would help its users to capture a rephotograph more accurately and allow them to share the scenes amongst other users. The designed application uses available on-device sensors to navigate the user to the location and guide the user during the rephotography process to capture a precise rephotograph. Furthermore, the application contains user interface elements designed explicitly for rephotography. Moreover, the work describes topics about user interface design, iOS application development, and designing and deploying backend API for the mobile application.

The goal of MDD is to reduce the semantic distance between a problem and its solution specification. Therefore MDD focuses on high-level abstraction modeling and successive model transformations, until finally, generate code. Studies assert that model-driven development can be significantly more efficient than traditional source code-driven software development and still reduce the possibility of occurrence of several problems during the software life-cycle. Likewise, Web engineering can also be benefited by MDD adoption, especially when supported by approaches that facilitate MDD use. Web development is usually agile with frequent releases, these approaches must be flexible to adapt to this context. However, generally, the approaches proposed by the academic community have complex processes which involve many different model definitions, programming languages, plug-ins and IDEs. These features contradict the practices adopted by Web developers. This paper presents the MWDA (Model-Driven Web Applications) approach that provides a simple process to support model-driven web development. This approach does not depend on tools, technologies or plug-ins and encourage combination with other forms of reuse and development processes. Furthermore, the Ruby- MDWA was developed with Ruby language and Ruby on Rails framework support, in order to create Web applications with MDWA assistance. This tool provides a set of textual models and defines M2M and M2C transformation tools, maintaining the requirements traceability since its specification to its construction and further maintenance. In order to show the use of the approach and tool, it was performed a real study case with a software company, from São Carlos SP, where a project management system was developed. In parallel, two experiments were conducted with undergraduate students in Computer Science and Computer Engineering and a Masters in Computer Science, to evaluate the gains and limitations of the Ruby-MDWA tool. / As técnicas de desenvolvimento de software evoluem continuamente com a finalidade de melhorar processos de construção e manutenção de software, além de obter ganhos em tempo, custo e qualidade. O objetivo do MDD é reduzir a distância semântica entre um problema e a especificação de sua solução. Para isso, MDD tem enfoque na modelagem de alto nível de abstração e em sucessivos refinamentos dos modelos construídos em artefatos mais detalhados, até enfim, gerar código. Há afirmações de que o desenvolvimento orientado a modelos pode ser significativamente mais eficiente que o desenvolvimento tradicional guiado por código fonte, além de reduzir a possibilidade de ocorrência de uma série de problemas durante o ciclo de vida do software. Da mesma forma, a engenharia de aplicações Web também pode ser beneficiada pela adoção de MDD, em especial com o apoio de abordagens que facilitem sua utilização. Como o desenvolvimento de aplicações Web comumente é ágil e com publicações freqüentes, essas abordagens devem ser flexíveis para que se adaptem a esse contexto. Entretanto, em geral, as abordagens propostas pela comunidade acadêmica apresentam processos complexos que envolvem diversos modelos, linguagens de programação, plug-ins e ambientes de programação. Essas características contrariam as práticas aprovadas pelos desenvolvedores Web. Esta dissertação apresenta a abordagem MDWA (Model-Driven Web Applications) que fornece um processo simples para desenvolvimento de software Web com apoio de MDD. A abordagem não depende de ferramentas, tecnologias ou plug-ins e estimula a combinação com outras formas de reuso e processos de desenvolvimento. Além disso, foi construída uma ferramenta, denominada Ruby-MDWA, baseada na linguagem Ruby e no framework Ruby on Rails destinada à criação de aplicações Web com auxílio da abordagem MDWA. Essa ferramenta fornece um conjunto de quatro modelos textuais e define transformadores M2M e M2C, que mantém a rastreabilidade de um requisito desde sua especificação até sua construção e posterior manutenção. Para mostrar o uso da abordagem e da ferramenta, foi realizado um estudo de caso real em conjunto com uma empresa de software de São Carlos SP, onde um sistema de gerenciamento de projetos foi desenvolvido. De forma paralela, foram conduzidos dois experimentos com alunos de graduação em Bacharelado em Ciência da Computação e Engenharia de Computação e mestrado em computação da UFSCar, visando avaliar os ganhos e as limitações da ferramenta Ruby-MDWA.

There are also typical application cases and requirements for camera trap construction described in this thesis.

In the emerging Web of Data, publishing stable and unique identifiers promises great potential in using the web as common platform to discover and enrich data in the ecologic sciences. With our collaborative e-Science platform “BEFdata”, we generated and published unique identifiers for the data repository of the Biodiversity – Ecosystem Functioning Research Unit of the German Research Foundation (BEF-China; DFG: FOR 891). We linked part of the identifiers to two external data providers, thus creating a virtual common platform including several ecological repositories. We used the Global Biodiversity Facility (GBIF) as well the International Plant Name Index (IPNI) to enrich the data from our own field observations. We conclude in discussing other potential providers for identifiers for the ecological research domain. We demonstrate the ease of making use of existing decentralized and unsupervised identifiers for a data repository, which opens new avenues to collaborative data discovery for learning, teaching, and research in ecology.
