REF PART LIBRARY

Entities are the basic data structures of the schema. They are defined by structured collections of one or more data attributes. An attribute provides detail of part of an entity description. There are mainly two types of attribute, predefined and composite. Predefined attribute types include integer, real, logical, and string. Composite types are declared explicitly in the schema - for example, the attribute type REF PART LIBRARY which indicates a reference to an entity in a part library by grouping the three necessary attributes together will be defined as a composite attribute. Some collections of attributes may appear both as entities and as composite attributes, for example POINT. ...

Fig. 12. Sequence spaces for the sequence/structure shown in the right column, (a) Sequence for ssRNA of length 3 with monomers G and A only, (b) Part ofthe sequence space for the 1,4-benzodiazepin-2-one derivative library constructed in Ref. 156. For clarity, not all neighbor relations are shown with lines in this figure. Points which differ at one site are called 1-mutant neighbors. For example, the points marked o are all 1-mutant neighbors of the point marked .

The concept of activity and activity coefficients are found in most physical and analytical chemistry texts that consider ionic equihbria. The texts listed in Ref. 4 are part of the author s personal library.
