The eml-software module contains general information that describes software resources. This module is intended to fully document software that is needed in order to view a resource (such as a dataset) or to process a dataset. The software module is also imported into the eml-methods module in order to document what software was used to process or perform quality control procedures on a dataset. The eml-software module, like other modules, may be "referenced" via the <references> tag. This allows a software resource to be described once, and then used as a reference in other locations within the EML document via its ID.

All datasets where software was used in the analysis or creation of the dataset. yes Software Package Defines a software distribution and all of its dependent software. The software element contains general information about a software resource that is being documented. This field is intended to give information for software tools that are needed to interpret a dataset, software that was written to process a resource, or software as a resource in itself. It is based on eml-resource and Open Software Description (OSD) a W3C submission. There can be multiple implementations within a software package because a physical software package can run on multiple hardware and/or operating systems. See implementation element documentation for a more thorough explanation. Implementation Describes the hardware and/or operating system requirements for one implementation of a package. Implementation describes the hardware, operating system resources a package runs on. Note, a package can have multiple implementations. So for example, a package may be written in java and the package may run on numerous hardware and/or operating systems like Pentium/Linux, Pentium/NT and so on. Hardware and Software descriptions that have different requirements can be placed here. Please see the examples for each subelement of the implementation type. Distribution Information on how the resource is distributed online and offline This field provides information on how the resource is distributed online and offline. Connections to online systems can be described as URLs and as a list of relevant connection parameters. Physical Size Physical size of an implemetation. The physical size of an implemetation on disk. 100 Megabytes International Language The International Language of the software implementation.

This element and its enumerations of assert and install can be used as commands by a software application to carry out these actions on software package dependencies. This is a change from how we have used all previous elements within eml. Up until now all other elements have been simply metadata designed to describe data, literature citations, etc... with the Action element we can use this module as a command to carry out the action. Dependency Dependency describes the software package(s) that the software package is dependent upon. The dependency element is recursive. It is a sub-element of the software Element but it also has as a sub-element its parent element Software Package. Dependecy has been made optional because to make it mandatory does not allow the recursion to end. Dependency has also been made a sub-element of implementation because there can be both implementation and package level dependencies within a package.
