Part-Whole relationships. Part(s) describing surronding Whole.

The idea is to develop kind of data structure, with parts nested compounding a whole, and the inner parts of the structure knows, in reverse order, the containing tree of elements or structure around it.

1: Definitions:

1. superPart: Part containing one or more parts.
2. part: Inside a superPart. Can contain subParts.
3. subPart: Inner unit inside a part.
4. NID: Nesting level ID (deep level entities are in a nested/tree structure)

   XML Example:

   <superPart NID="0"> <part NID="1"> <subPart NID="2"> </part> <! -- end NID 1 --> </superPart> <! -- end NID 0 -->
5. SeqID: Sequence ID (symbol sequencing and identification)

   Symbols sequencing and identification begins with first occurrence of a symbol in a structure, begining with 0, next symbol is tagged with 1. If next symbol appeared before, then the tag used before to identify it is used.

6. OccID: Occurrence ID

   Times element appeared in a sequence. First time same element occurs is 0, then 1, etc.

7. CID: Count ID (0, 1, 2,...)

   Sequential count, begining with 0, of elements in determinate context (Nesting level, Sequence, etc.)

8. MvtID: Movement ID

   Signals start (S), inside (I), outside (O) or end (E) movement in a statement chain.

2. Example:

• Linear Form:

( superPart ( part ( ( superPart ) ( subPart ( part ( superPart ) ) ) ) ) NID: 0 1 2 2 3 4 SeqID: 0 1 0 2 1 0 OccID: 0 0 1 0 1 2 CID: 0 1 2 3 4 5 MvtID: S I O I O E

• XML Example:

<superPart NID="0"> <part NID="1"> <superPart NID="2"/> <subPart NID="2"> <part NID="3"> </superPart NID="4"> </part> </subPart> </part> </superPart>

• Another Example:

( head ( face ( ( head ) ( eyes ( face ( head ) ) ) ) ) NID: 0 1 2 2 3 4 SeqID: 0 1 0 2 1 0 OccID: 0 0 1 0 1 2 CID: 0 1 2 3 4 5 MvtID: S I O I O E3. Composite IDs:

Combining CID, NID, SeqID and OccID, other IDs for easier retrieval of elements in statement can be achieved.

For example: NID + OccID = CID (Count of elements inside a specific nesting level)

( head ( face ( ( head ) ( eyes ( face ( head ) ) ) ) ) NID: 0 1 2 2 3 4 SeqID: 0 1 0 2 1 0 OccID: 0 0 1 0 1 2 CID: 0 1 2 3 4 5 OrderID: (0. 0) (1. 0) (2. 0) (2. 1) (3. 0) (4. 0)
4. Terms (Parts) Relationships and Roles:

In specific context of container part, another part plays a role or function in the context of container part. This is the semantics of the containment relationship, for example: John, inside a specific Team, is a player, more specificaly, a goalkeeper.

Parsing Example:

[previusElement]:[role/type] => [actualElement]:[role/type] => [nextElement]:[role/type]
5. Measurement units: superUnit (eg. : Kilometer) unit (eg. : Meter) subUnit (eg. : Centimeter) Ratio: superUnit (1) => unit (1/n) => subUnit (1/n : n)
