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:
superPart: Part containing one or more parts.
part: Inside a superPart. Can contain subParts.
subPart: Inner unit inside a part.
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 -->
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.
OccID: Occurrence ID
Times element appeared in a sequence. First time same element occurs is 0, then 1, etc.
CID: Count ID (0, 1, 2, ...)
Sequential count, begining with 0, of elements in determinate context (Nesting level, Sequence, etc.)
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 E
3. 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)
