Abstract

A method is disclosed for defining the structure of a document by specifying the relationships between document elements in a data stream. A plurality of tabular specifications are provided, each of which includes a number of document elements. The logical relationship between each document element and all other document elements within each tabular specification is specified once for the entire tabular specification. The semantic interpretation for each tabular specification is associated with a named reference to that tabular specification so that multiple references to that tabular specification may yield different semantic interpretations. In this manner, it is possible to minimize the amount of specification to define a document by utilizing individual tabular specifications repeatedly. Additionally, a reference to a tabular specification may be utilized to modify the existing logical relationship between the document elements contained therein. In a preferred embodiment of the present invention, a range of allowable values for individual document elements within a tabular specification may be specified by the user.

Claims

1. A computer implemented method in a data processing system of defining relationships among elements in a multidimensional architecture, said computer implemented method comprising the steps of:

creating within said data processing system a plurality of tabular specifications, each of said tabular specifications including a plurality of elements;

specifying once for each of said plurality of tabular specifications the logical relationship between each of said plurality of elements contained therein and at least one other element contained therein;

storing said specified logical relationship in association with each of said plurality of tabular specifications;

accessing said plurality of tabular specifications and said associated specified logical relationships; and

defining relationships among elements in a multidimensional architecture by reference to said accessed plurality of tabular specifications and associated specified logical relationships.

2. The method according to claim 1, further including the step of specifying within each of said plurality of tubular specifications a range of allowable values for at least one element contained therein.

3. The method according to claim 1, wherein at least one reference to a selected one of said plurality of tabular specifications is contained within a second tabular specification.

4. The method according to claim 1, further including the step of selectively altering the logical relationship between each of the elements contained within a particular accessed tabular specification in response to an access thereof.

5. A computer implemented method in a data processing system of defining the structure of a multi-element entity within a data stream, said computer implemented method comprising the steps of:

creating within said data processing system a plurality of tabular specifications, each of said tabular specifications including a plurality of elements;

specifying once for each of said plurality of tabular specifications the logical relationship between each of said plurality of elements contained therein and at least one other element contained therein;

storing said specified logical relationship in association with each of said plurality of tabular specifications;

accessing said plurality of tabular specifications and said associated specified logical relationships utilizing a reference which includes an indication of the semantic interpretation of the elements contained within at least one of said plurality of tabular specifications; and

defining the structure of a multi-element entity within a data stream by references to said accessed plurality of tabular specifications and associated specified logical relationships.

6. The method according to claim 5, further including the step of specifying within each of said plurality of tabular specifications a range of allowable values for at least one element contained therein.

7. The method according to claim 5, wherein said reference which includes an indication of the semantic interpretation of the elements contained within at least one of said plurality of tabular specifications is contained within a second tabular specification.

8. The method according to claim 5, further including the step of selectively altering the logical relationship between each of the elements contained within a particular accessed tabular specification in response to an access thereof.

9. A data processing system for defining relationships among elements in a multidimensional architecture, said data processing system comprising:

means for creating within said data processing system a plurality of tabular specifications, each of said tabular specifications including a plurality of elements;

means for specifying once for each of said plurality of tabular specifications the logical relationship between each of said plurality of elements contained therein and at least one other element contained therein;

means responsive to said means for specifying for storing a specified logical relationship in association with each of said plurality of tabular specifications;

means, coupled to said storing means for accessing said plurality of tabular specifications and said associated specified logical relationships; and

means responsive to said means for accessing for defining relationships among elements in a multidimensional architecture by reference to said accessed plurality of tabular specifications and associated specified logical relationships.

10. The data processing system for defining relationships among elements in a multidimensional architecture according to claim 9, further including means for specifying within each of said plurality of tabular specifications a range of allowable values for at least one element contained therein.
