Although governments publish large amounts of open data, their use by the public sector is still in its infancy. Therefore, this study aims to gain insights into promoted benefits and factors that hinder (barriers), facilitate (enablers), and propel (drivers) Open Government Data (OGD) use and reuse by the public sector. A systematic literature review of 38 publications resulted in an overview of these factors. Findings suggest that OGD use benefits are increased transparency and the development of new/improved processes, products, and services. Moreover, open data institutionalization and pressure from external stakeholders drive the use. However, data issues and the lack of supporting open data organizational structure, capacity, and skills hinder OGD use. While the existence of open data policy and laws, motivated leadership, and open data infrastructure enable it. Thus, if OGD use is to reach maturity, administrations need to create the means to institutionalize open data.
As e-government initiatives progressed, several models for measuring e-government maturity were proposed. Many are stage models based on the Capability Maturity Model (CMM) in which e-government maturity is conceptualized as stages of growth that evolve over time. The paper aims to investigate if e-government stage maturity models measure the use and usefulness of egovernment. A meta-synthesis technique was used to compare and contrast 11 meta-models (models derived from other models), at the stage level, for their perspectives, concepts, metaphors, and their similarities and differences. We found that although models use different names and metaphors for analogous concepts, similarities exist among them, and individual stages overlap. Results show two gaps in research regarding the assessment of the actual use and usefulness of e-government. First, meta-models primarily assess the supply-side and operational/technology and citizen/service perspectives. Second, the use and usefulness of e-government are not addressed.
This paper describes a Service Oriented Architecture (SOA) based on Web services technology designed to assist cultural heritage institutions in the implementation of migration based preservation interventions. The proposed SOA delivers a recommendation service and a method to carry out complex format migrations. The recommendation service is supported by three evaluation components that assess the quality of every migration intervention in terms of its performance (Migration Broker), suitability of involved formats (Format Evaluator) and data loss (Object Evaluator). Throughout the paper the whole workflow between these three components is explained in detail as well as the most relevant tasks that carried out internally in each of them. The proposed system is also able to produce preservation metadata that can be used by client institutions to document preservation interventions and retain objects' authenticity. Although the primary goal of this SOA is the implementation of migration based preservation interventions, it can also be used for other purposes such as comparing file formats or evaluating the performance of conversion applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
