Language Design
Object-Process Methodology (OPM) is a modeling language. OPM combines a minimal set of building blocks – stateful objects and processes that transform them – with a dual graphic-textual representation in a single diagram type.
OPM uses two types of elements: entities and links. Entities are used to express "physical" or "informational" elements which can be inside or outside of the system being designed, i.e. "systemic" or "environmental".
The entities used in OPM are objects, states and processes. An object is a thing existing for a period of time. A state is a situation an object can be in. A process is a phenomenon that transforms one or more objects by creating them, altering their states or destroying/consuming them.
The links used in OPM are structural links and procedural links. A structural link forms a relation between two objects and is persistent. A procedural link is used to link a process to an object - in which case it indicates a change in the state of the object - or to another process - in which case it indicates the launching of the second process when the first ends.

Famous quotes containing the words language and/or design:
“I suggested to them also the great desirability of a general knowledge on the Island of the English language. They are under an English speaking government and are a part of the territory of an English speaking nation.... While I appreciated the desirability of maintaining their grasp on the Spanish language, the beauty of that language and the richness of its literature, that as a practical matter for them it was quite necessary to have a good comprehension of English.”
—Calvin Coolidge (1872–1933)
“With wonderful art he grinds into paint for his picture all his moods and experiences, so that all his forces may be brought to the encounter. Apparently writing without a particular design or responsibility, setting down his soliloquies from time to time, taking advantage of all his humors, when at length the hour comes to declare himself, he puts down in plain English, without quotation marks, what he, Thomas Carlyle, is ready to defend in the face of the world.”
—Henry David Thoreau (1817–1862)
