Visualizing Research Digital Libraries with Open Standards

Large scale research Digital Libraries (DLs) have a large array of potentially useful metadata. Yet, many popular DLs do not provide a convenient way to navigate the metadata or to visualize classification schema in the user session. For example, in the broad world of Management Information Systems (MIS) research, a high-level overview of MIS topics and their interrelationships would be useful ...

Standards for Digital Libraries and Archives: Digital Longevity

There is a lack of durable thinking on digital longevity. For this we require cross-domain communication and acceptation of standardized concepts, procedures, document formats and IT-tools. Four kinds of standards are required for preservation of digital documents over an indefinite period of time: standards for the architecture, document format standards for preservation, metadata standards fo...

Evaluation of the Iranian academic library collections based on the Standards of Iran University Libraries (SIUL) standards

Sampling Efficiency in Digital Camera Performance Standards

One of the first ISO digital camera standards to address image microstructure was ISO 12233, which introduced the SFR, spatial frequency response, based on the analysis of edge features in digital images. The SFR, whether derived from edges or periodic signals, describes the capture of image detail as a function of spatial frequency. Often during camera testing, however, there is an interest in...
