Item An open source software selection process and a case study(2009-06-02) He, GuobinIn this study, I design an empirical open source software selection process, which reuses some ideas from Commercial Off-the-Shelf selection methods and addresses the characteristics of the open source software. Basically, it consists of three basic steps: identification, screening and evaluation. The identification step is to find all possible alternatives to open source software that can meet the high level requirements. The next step is screening, in which the refined requirements are applied to filter the alternatives. The evaluation step is based on the Analytic Hierarchy Process, in which the alternatives are inspected from functional suitability, source code, support strength and popularity. In more detail, under functionality suitability criterion, alternatives to open source software are evaluated in viewing of how much functionality can fit in with the functional user requirements. The source code of the alternatives is evaluated from six criteria: programming language, code size, code comment, code intra-module complexity and code inter-module complexity. The evaluation of support strength depends on the evaluation of field support and support resources. The field support includes commercial support and community support. The community support specifically refers to the direct responses from the community to the support requests. Aside from field support, open source software projects also provide various support-related resources such as, documents, wiki, blog, etc. To determine the popularity of the alternatives, I evaluate them from software use, development participation and web popularity. In the case study, I utilize the process to select the best open source unified modeling language tool from the ten alternatives for the software development process. After the screening phase, the four competitive alternatives, BOUML, ArgoUML, UMLet and Violet, are evaluated from functionality, source code, support strength and popularity criteria. The evaluation result indicates that ArgoUML is the best tool for the requirement. The case study demonstrates the effectiveness of the selection process. Various important attributes of open source software are taken into consideration systematically and the final decision is reached based on comprehensive investigation and analysis. The process provides an operable solution to the open source selection problem in practice.Item Implementing Open Source Systems for Digital Asset Management and Preservation(2016-05-26) Weidner, Andrew; Krewer, Drew; Scott, Bethany; Watkins, Sean; University of HoustonThe University of Houston (UH) Libraries recently completed the comprehensive evaluation and testing of multiple systems for digital asset management and preservation. In concurrent efforts, a Digital Asset Management Systems Task Force (DAMSTF) and Digital Preservation Task Force (DPTF) selected open source solutions – Hydra and Archivematica, respectively – for the long term stewardship of the UH Libraries’ digital collections. Members of the DAMSTF and DPTF will provide an overview of the systems implementation process and discuss some of the challenges that the implementation team has faced along the way.Item Introduction to DSpace(2016-12-08) Lindsey, Nerissa S.; McElfresh, Laura KaneItem Multilingual User Interface Options for Open Source Library Technology(Texas Digital Library, 2023-05-16) Oduok, ImaLinguistic accessibility is often overlooked in overall discussions of software and website usage. As part of my residency, I looked at the linguistic accessibility of several TDL open source software platforms to assess what is currently available and what isn’t. Part of that assessment was identifying what options may exist to expand the selection of available translations. This session will break down the current language offering for TDL supported platforms, limitations, and potential solutions for the future.Item Outside The Box: Building a Digital Curation Ecosystem for Preservation and Access(2017-05-24) Weidner, Andrew; Watkins, Sean; Scott, Bethany; Krewer, Drew; Washington, Anne; Richardson, Matt; Wu, Annie; Thompson, Santi; University of HoustonThis presentation covers the tools and workflows that the University of Houston (UH) Libraries have developed to facilitate digital curation activities for our new repository architecture based on Hydra-in-a-Box, Archivematica, and ArchivesSpace, collectively known as the Bayou City Digital Asset Management System (BCDAMS). BCDAMS development work began in early 2015 as an extension of a one and a half year process to evaluate and test DAMS. As a whole, these workflows and tools create an ecosystem that supports the long term preservation and access of the digitized cultural heritage materials in the UH Libraries unique collections. The project team, consisting of members from Digitization, Metadata, Special Collections, and Web Services, employed an agile development methodology to lay the foundation for the UH Libraries migration from our current system to the BCDAMS. Over nine development cycles, each lasting approximately one month, the BCDAMS team created five applications (named for bayous in the Houston metropolitan area) that address key issues in digital curation: - Persistent identification of digital resources (Greens) - Local management of linked data vocabularies (Cedar) - Preparation of files and metadata for Archivematica ingest (Carpenters) - Metadata editing for Hydra-in-a-Box ingest (Brays) - Representation of archival collections in ArchivesSpace (Halls) In addition, the project team began the complex process of descriptive metadata analysis and remediation to prepare for collection migration, resulting in a Ruby gem for downloading metadata through the CONTENTdm API and an online metadata application profile that is shared by all systems. Each development cycle ended with an internal report documenting the project’s progress.
