Hi all,

as for the discussion on whether we should use chaining (prev / next links) or simple integer numbers for representing order, I have a firm preference for the latter (i.e. a property itemPosition rather than prev / next links). In fact, in GoodRelations, we introduced the latter e.g. for ordering days of the week because the first approach did not work too well.

This is for the following reasons:

1. Chaining works well only with "perfect" data - consistent and complete. If you miss one element (e.g. due to invalid markup etc.), you are lost. Data on the Web is typically noisy and buggy, so the conceptual beauty of chains comes at the cost of unreliability.

2. Chaining blows up the markup - you typically have two properties per each entity (one to the previous, one to the next).

3. Most importantly: For consumers of the data, it is much easier to sort items by a single literal than to reconstruct the ordered list from the chain structure. That was the reasons why the days of the week in GoodRelations now have an integer value indicating their position.

As for the question on representing the order of entities that form the list: This must, IMO, be solved with a dedicated data structure, since the position in the list is always a property of the entity solely in the context of that list and not a globally valid property of the entity. Think of a list of favorite actors or songs - the same items can be ordered completely different on different sites.

So I revisit my proposal and suggest to add a property 

	represents Thing The entity represented by the entry in the list (e.g. the artist, song, ...).

The you can define the actual entity inside the list entry and link to it from the list element.

The full proposal is attached.

This should cater for all use-cases discussed so far.

Martin

Apparently we're missing a proper way to add 'order' to schema.org. This doesn't only count for an ItemList but for example also faults in being able to declare the order of a series of WebPages (book) or images (IKEA manual), etc.

If you want to be able to model the entity independently of the list item and have a formal link between both, we need an additional property. But then this should maybe be a generic property for linking entities and their representation (maybe from the library extension, did not check), and we are also in the middle of philosophical distinctions that are, while valuable, difficult to teach to broad audiences ;-)

A counter argument is that while Table is a significant Web page element type, List is a more generic data structure and not constrained to Web pages. (But then again, some tables outside of HTML markup, e.g. in JSON-LD or CSV, are also not WebPageElements in the strict sense).

How entities are a constituent of higher level goals and processes is probably the real answer to better search. If not search, they would be a very interesting in terms of knowledge discovery - such as being to ask 'What happens at the Chile embassy [location]?' in Sam's example, to use just one permutation of many possible questions. Bringing all this to a scale such as the web would be very exciting.

The key difference is that you probably want to specify the step number instead of relying on page layout as parsers often discard the order of elements.

Rankings for processes are also different to content backlinks, which we are working on, as you could define pre-requisites (do this before doing this) and chain processes after (after doing this - continue with this).

For example - the list, "How to enjoy a great Saturday night in" might have a reference to a food - pizza AND a movie - as an entity, etc. Granted, the example isn't the best, but it's entirely unrelated to any specific thing.
