compact-0018

I think there's a problem in compact-0018 regarding finding the appropriate terms for term1 and term2.

The test includes two lists, associated with an IRI shared between term1 and term2. The difference is that term1 and no language defined, and term2 has a language different from the default of the context ("en" vs "de").

The result comes down to calculating the term ranks for each value in the list. I come up with the following calculations:


value

term1

term2

{ "@value": "v1.1", "@language": "de" },

3

0

{ "@value": "v1.2", "@language": "de" },

3

0

{ "@value": "v1.3", "@language": "de" },

3

0

4,

2

1

{ "@value": "v1.5", "@language": "en" },

1

3

{ "@value": "v1.6", "@language": "en" }

1

3

total (term1)

13

7







{ "@value": "v2.1", "@language": "en" },

1

3

{ "@value": "v2.2", "@language": "en" },

1

3

{ "@value": "v2.3", "@language": "en" },

1

3

4,

2

1

{ "@value": "v2.5", "@language": "de" },

3

0

{ "@value": "v2.6", "@language": "de" }

3

0

total (term2)

11

10


(pardon the formatting)

Basically, I find that term1 is selected in both cases, which results in an illegal compaction, as a term with @container: @list can't have two list values.

The playground, and presumably Markus' implementation does allocate between term1 and term2, so it seems that there's an inconsistency.

I think the test would be just as valid if v1.5 were "de" and v2.5 were "en", which would give the totals of 15 and 4 for the v1.x values and 9 and 13 for the v2.x values, which would result in the proper allocation.

Am I missing some detail in the algorithms?
