Re: [whatwg] inverse property mechanism for Microdata?

Yes. I notice that the words we were playing with at schema.org relate to the underlying graph data model itemprop-inverse, -reverse etc., whereas your draft name, itemprop-up is about the markup hierarchy. Yeah. I think most authors think in terms of what they see (their markup), not in terms of the data model. (I have had a _lot_ of conversations with authors where it was clear that they had no idea there was an underlying data model for the microdata that was separate from the markup.) Yup, there are some cases where this can be addressed through the rigorous use of entity IDs in itemid, as you sketch below. That would be relatively new territory for schema.org and for publishers. Perhaps there is an attribute name we can find that would leave the door open to more use cases, e.g. itemprop-backwards rather than itemprop-up. It seems reasonable to try to address relationships between sibling elements too. Well you'd been a new attribute to do that, unless I'm misunderstanding your proposal. Maybe you mean this attribute wouldn't point to a relative place in the markup, but would point to an identified element given by another attribute? I think that would be quite confusing. Something like (trying out -backwards instead of -up, to allow for non-hierarchical usage): div itemid=bigshop itemscope itemtype=http://schema.org/LocalBusiness; h1span itemprop=name(Entity A) Beachwalk Beachwear Giftware/span/h1 /div div itemscope itemtype=http://schema.org/Pharmacy; meta itemprop-backwards=containedIn itemid=bigshop / h2span itemprop=nameTiny pharmacy store within a store/span/h2 /div ? Can we use itemid in that way, to give a property value too? I don't see itemid used much in the wild and the spec only mentions its use for the item having the property, rather than using when supplying the value of a property. itemid= is a URL that gives the identifier of the item. We'd want to use a new attribute to do something like this; e.g.: itemrelation=containedIn bigshop where itemrelation takes just two keywords, a property name and the ID (not itemid) of the target element. But that's pretty elaborate. Is there a need for this? Or is the relationship to the parent all that's needed? In your original e-mail you only suggested wanting to go up. Microdata actually already has a solution to this. The vocabulary can define an ID for each item using itemid=, and can define multiple items having the same ID as being the same conceptual item. Thus: !-- first episode -- div itemscope itemtype=http://schema.org/Episode; ... div itemprop=actor itemscope itemtype=http://schema.org/Person; itemid=http://.../person/123;/div div itemprop=actor itemscope itemtype=http://schema.org/Person; itemid=http://.../person/456;/div /div !-- second episode -- div itemscope itemtype=http://schema.org/Episode; ... div itemprop=actor itemscope itemtype=http://schema.org/Person; itemid=http://.../person/123;/div div itemprop=actor itemscope itemtype=http://schema.org/Person; itemid=http://.../person/456;/div /div !-- actors -- div itemscope itemtype=http://schema.org/Person; itemid=http://.../person/123; ... /div div itemscope itemtype=http://schema.org/Person; itemid=http://.../person/456; ... /div This also enables the data to be spread across multiple pages without confusion. (This is similar to how RDF uses identifiers for everything -- essentially, in RDF terms, this turns the microdata item from a bnode into a node with a global identifier.) Yes, it succeeds or fails to the extent people agree on these global identifiers. Do people not agree on them, typically? Your example would become: div itemscope itemtype=http://schema.org/LocalBusiness; itemid=... h1span itemprop=name(Entity A) Beachwalk Beachwear Giftware/span/h1 span itemprop=description A

Is there a security reason to prefer the latest navigator? Agreed, the specified behaviour makes sense to me, if only because of the name. The fact that you can also use window.open for subsequent navigation (which leads to the different behaviours), muddies the water a bit, but that's a genie that would definitely refuse to go back in the bottle. Over security reasons, although I don't have any concrete examples, I would have thought that either could possibly cause problems, if the opposite behaviour was expected. So, consistency is probably the most important thing. I can also see that both pieces of information (original opener and last navigator) might be useful. So, maybe the other could be added either way.

I was hoping there might be other people with opinions, to give us different perspectives on this, but it seems nobody else cares. :-( Since you asked, I think the whole endeavour (of trying to tokenise an address) is pointless and should be abandoned outright. :) In principle I agree, but in practice I think we have to work with the reality that that is what people are doing. Short of my ideal of *only* offering the full address (as used on a label) as an opaque string, I think it would be most reasonable to consider the 'locality' field itself to be a fully-specified opaque string, including whatever information is necessary to completely identify the location from the region level (such as the prefecture and district), rather than a single level. Failing all that, I would at least prefer for the fields to have names instead of abstract numbering, because people are likely to be confused about the order, no matter which end is the 'widest'. It also seems more intuitive, to me, for the 'locality', as, after all, 'local', to be the most specific level. Would people not be confused by names in the same way?

Yes, this alternative works, but in my opinion is not preferable. Because these words don't really mean anything. Nor do numbers.

Also in a natural-language conversation, if you ask me what region of the country I live in, I'd say New England, the Midwest, or some such; certainly not the state where I reside. The descriptions for these tokens are currently pretty specific, for example they say a city would be a locality. But this is not true for Beijing or some other cities. To fix the descriptions, we'd have to change them to something like region: the highest level administrative region below country in the address and locality: the second-highest level administrative region below country in the address, sub-locality: the third-highest level administrative region [...]. With you so far. At this point, one wonders why the tokens aren't just [something]1, [something]2, etc. I don't understand how you get there. Why would you wonder this? address-line1 | address-line2 |- street-address address-line3 | locality subsubregion subregion region country-name I don't understand why you think authors will think they need to include subregion, but won't think they need to include address-level3. I think they'll assume subregion returns something for the US if it's sandwiched between region and locality, because county is in between state and city. But in reality, subregion will return nothing. But why does this not apply to the numeric version? Having synonyms is really bad. It leads to huge amounts of confusion. This is why I'm trying to avoid having synonyms for the address-level* stuff. We should definitely not add some just to introduce a slightly better name. My suggestion is to change the address-line1 to street-address-line1, not to have synonyms. Chrome would then support address-line1 for a limited period of time, but outside the spec. There's no outside the spec. The spec tries to describe reality. If you implement something, then that's the reality, and that's what the spec would say, and therefore we'd have

Although, the history case might hold the original state. Anyway, getting way ahead of myself. I'll see if there are any more opinions, then look to move Gecko towards the spec and see if any compat issues arise.
Re: [whatwg] More effective model for handling resources
Hi Ian, I believe this is being handled by the next-generation transport protocols (SPDY or whatever it's called now). I recommend approaching the relevant groups to check that your precise case has been handled. I just found out that SPDY Server Push and Cookies could accomplish the above mentioned caching. Cookies will take care of information providing. And the server just uses Server Push to push content.
