Glossary¶
- DMF
- Data Management Framework. This is the overarching component.
- data files
- Files, text or binary, that are tracked by the DMF by being associated with one or more resources.
- flowsheet
- An object that encapsulates the connections between models to create a meaningful end to end description of a process.
- property data
- A set of values relating to measured properties for chemical compounds or other components of interest. For example, pressure and temperature data.
- property model
- A model, usable in Pyomo, for calculating property values based on property data.
- Pyomo
- Python-based, open-source optimization modeling language used to perform all the underlying computation for the models. See the Pyomo website for more details.
- relation
- A connection between two resources. These connections have labels, such as “contains” or “derivedfrom”. They can be expressed as triples of the form (subject, predicate, object), which is not coincidentally the basic unit of the Resource Description Framework (RDF), a web data interchange standard.
- resource
- A distinct object stored in the DMF, e.g., a unit model, flowsheet, property data package. Resources have a unique identifier, and may connect to each other.
- unit model
- A Pyomo “block” that models one unit in a flowsheet.
- workspace
- The container for a set of DMF resources and files. Associated with a configuration file. All DMF actions occur within a single workspace.
