The Processing_Information dictionary contains detailed information regarding the history of processing performed on data product(s) in order to produce the current product. ## CHANGE LOG ## 1.2.0.0, T.Hare - upgraded to v1.13.0.0 of the IM - Allow Software to be many (unbounded) to allow for many applictions to be listed for one process. 1.2.1.0 T.Hare - update for 1.E.0.0 and 1.F.0.0 and new github C.I. environment - Changed all class local_identifier to identifier_reference per v1900 IM update The Input_Product class describes one of the product most directly used as input to software for product creation, including raw, partially-processed, calibrated, or derived products. The Input_Product_List class describes all of the product(s) most directly used as input to software for product creation, including raw, partially-processed, calibrated, or derived products. These Input Products can be explicitly described in this label using the Input_Product class, and/or a list of products can be specified in another product referenced by the Internal_Reference or Local_Internal_Reference. The Parameter class describes any information about software program execution. Examples of information that can be captured here are software input arguments, software output arguments, log information, and references to specific data products. This class is intended to be freeform to allow data providers the ability to specify information they determine applicable and useful for their data processing software and data products. The Process class describes one of the software processes used to produce the data product referenced in the parent Processing_Information class. This class includes descriptions of the process owner as well as the data processing software used to create the data product. The Processing_Information class contains detailed information regarding the history of processing of the data product(s) described in the label. Information that can be specified using this class includes input products used to create a specific data product and the software and processes used to produce that product. The Software class describes the data processing software used in order to produce the data product. The Software_Program class describes the specific components or tasks of the Software executed in producing the data product. The Software_Program_Parameters class specifies the set of 1 or more parameters for the software program. These parameters can be input, output, or log information. The premise being a way to capture as much information as possible about the software program execution. This section contains the simpleTypes that provide more constraints than those at the base data type level. The simpleTypes defined here build on the base data types. This is another component of the common dictionary and therefore falls within the common namespace. The parameter_type attribute specifies the type of software parameter. Valid values: 'Input' - this parameter specifies input data, 'Output' - this parameter specifies output data, 'Log' - this parameter specifies log data The pprocess_owner_institution_name attribute specifies the name of the institution that owns the software process. The pprocess_owner_name attribute specifies the name of the person or organization that owns the software process. The program_hostname attribute specifies the machine hostname where the software program was executed. The program_path attribute specifies the file path to the software program. This path can be absolute or relative depending on the desired usage. The program_start_date_time specifies the datetime for the start of the software program execution. The program_start_date_time attribute specifies the datetime for the end of the software program execution. The program_type_name attribute specifies the type of software program used for this software processing. Some examples include: VICAR, ISIS, GDAL. The program_user attribute specifies the username of the person responsible for running the software prgoram. The program_version attribute specifies the version of the software program.
