Example
Planned useI would like to add information about where the installable binary for a software application can be located.
See alsosource code repository URL (P1324)
Motivation

In order to provide Emulation as a Service, it would be useful to point to URLs at which installable binaries can be found. I would like to include two qualifiers that could with this property: 1) software package format 2) package structure.

Planned useI would like to add this property to scientific articles if the authors state the software used in the study somewhere in the text of the article.
Motivation

Creating relationships between the items for scientific articles and items for software will allow us to present more structured data about scientific publications.

TODO

[edit]
  • topicArea/ description/ example
  • supports / This property would describe formats supported by software / Amarok supports FLAC
  • Endianness/ This property would describe the order of the bytes comprising a digital word in computer memory. It also describes the order of byte transmission over a digital link. Words may be represented in big-endian or little-endian format / Q217570 byte order described in PRONOM
  • compression type / This property would describe how compression is achieved, ex naming the compression algorithm/ fmt/3 PRONOM LZW compression
  • UTI / This property would reference external IDs from Apple's uniform type identifier vocabulary / this exists as an item but perhaps we need a property for it
  • Info URI scheme/ This property would reference namespace descriptions from info-uri.info/ (exisits as an item but not a property) PRONOM -> http://info-uri.info/registry/OAIHandler?verb=GetRecord&metadataPrefix=reg&identifier=info:pronom/
  • lossiness/ This property would describe whether or not a compression type is lossy lossiness used in PRONOM
  • emulates/ This property would indicate the operating system emulated by an emulator
  • native file format (ChemDraw --> CDX)
  • validator available at URL (chemical markup language has a validator service)
  • software used/This property would describe software used in the context of a research project. I could see this being used on the items for scientific articles.
  • checksum
