consistency and compatibility Clause Samples
consistency and compatibility. To promote a cohesive plan of development, buildings shall have architectural features that offer common themes and styles while recognizing local character. Acceptable examples include Italianate Revival, Mediterranean, Neoclassical, and Art Deco Mission. Generally, the perimeter zone is envisioned as having more design flexibility than the core zone and can accommodate corporate headquarters that develop as a campus vs. a street front development due to image or security reasons.
consistency and compatibility. In order to get a better understanding of when the properties consistency [6,7,20] and compatibility [6, 7, 20] are relevant, a scenario is examined where a contract is used to out source the development of an element E with an interface X. Specifically, the scenario can be described in three phases:
1) a contract (A, G) and an interface specification X are handed from the client to a supplier;
2) an element E = (X, B) is delivered to the client that meets the condition (i) of Corollary 1; and
3) the client integrates the element E with a set of elements to form an archi- tecture where the environment of E meets the condition (ii) of Corollary 1. As expressed in phases (1-2), the client would expect the supplier to deliver an element that meets the condition (i) of Corollary 1 with respect to the contract C . However, in order for the supplier to be able to meet the demands from the client, the supplier would expect that the contract is such that there actually exists an element that meets the condition (i) of Corollary 1. If such an element exists, then the contract will be referred to as a consistent contract. Furthermore, in order for the client to be able to complete phase (3), at least one architecture containing an element E = (X, B) where the environment of E meets the condition (ii) of Corollary 1, needs to exist. If such an architecture exists, then the contract will be referred to as a compatible contract. Now that the concepts of consistency and compatibility have been introduced in the context of a scenario, formal definitions follow. ^ ^ ^^ Definition 7 (Consistent Contract). A contract (A, G) is consistent with respect to a set of variables X if there exists an element E = (X, B) such that AA ∩ B ⊆ G and AA ∩ G ⊆ B.
1. Definition 7 is also closely related to definitions in [6, 7], but where Definition 7, in contrast to the definitions in [6,7], allows contracts that are not limited to the interface and are further not limited to elements with defined inputs and outputs.
