General Purpose Optimization Library (GPOL): A Flexible and Efficient Multi-Purpose Optimization Library in Python

A General-Purpose Provenance Library

Most provenance capture takes place inside particular tools – a workflow engine, a database, an operating system, or an application. However, most users have an existing toolset – a collection of different tools that work well for their needs and with which they are comfortable. Currently, such users have limited ability to collect provenance without disrupting their work and changing environme...

General-Purpose Digital Library Content Laboratory Systems1

The last decade witnessed a proliferation of systems specially devised for aggregating and then operating over information objects – e.g., publications, experimental data, multimedia and compound objects – collected from possibly heterogeneous and autonomous data sources. Such systems, to which we refer as “Digital Library Content Laboratories”, are typically highly domain-specific and thus fea...

General purpose medical digital library definition

1 The need of an approach for the definition of a platform-independent medical digital library, using only 2 open-source tools, will be described. To test the need and the success of such an approach, a library will 3 be created, which can later be used in a larger scale as a general purpose digital medical tool, when comes 4 the need to evaluate an image. 5 As a first test, the library will be...

Stress-Testing General Purpose Digital Library Software

DSpace, Fedora, and Greenstone are three widely used open source digital library systems. In this paper we report on scalability tests performed on these tools by ourselves and others. These range from repositories populated with synthetically produced data to real world deployment with content measured in millions of items. A case study is presented that details how one of the systems performe...
