Wiki PageID

Hi,

I have a couple of questions regarding the Wiki Page ID. Does it always
stay unique for the page, where the page itself is just a placeholder for
any kind of information that might change over time?

Consider the following cases:
1. The first time someone creates page "Moon" it is assigned ID=1. If at
some point the page is renamed to "The_Moon", the ID=1 remains intact. Is
this correct?
2. What if we have page "Moon" with ID=1. Someone creates a second-page
"The_Moon" with ID=2. Is it possible that page "Moon" is transformed into a
redirect? Then, "Moon" would be redirecting to page "The_Moon"?
3. Is it possible for page "Moon" to become a category "Category:Moon" with
the same ID=1?

Thanks,
Gintas

Hello Gintautas!

information that might change over time?
That is indeed the idea. COntent changes, the page ID stays the same. If you
need to identify a specific state of the page, use the revision ID (aka permalink).

Note however that page IDs are considered "internal" identifiers. They are
stable, but they are not the canonical way to access or identify a page. Use the
title for that - or, in the context of Wikidata, use the entity ID.
1. The first time someone creates page "Moon" it is assigned ID=1. If at some
point the page is renamed to "The_Moon", the ID=1 remains intact. Is this correct?
Yes, page IDs survive renaming/moving the page.
2. What if we have page "Moon" with ID=1. Someone creates a second-page
"The_Moon" with ID=2. Is it possible that page "Moon" is transformed into a
redirect? Then, "Moon" would be redirecting to page "The_Moon"?
Yes, pages can become redirects.
3. Is it possible for page "Moon" to become a category "Category:Moon" with the
same ID=1?
Yes, pages can be moved into the category namespace.

Though I agree Daniel with what you wrote about redirects, we do have a
policy (I believe I have read this somewhere) that if you create a redirect
in the case of two items about the same thing, then it should always be the
older item number that survives (and the merge gadget is supposed to check
for this). Maybe that's too much detail information though. So for the
given example "Moon" was created first and thus it is "Moon" id that should
survive, whether or not the label is set to "The Moon" later.

Hi,

A number of years ago I was having some very frustrating times with the identifier instability in dbpedia. Two people looking up an identifier for the same concept at different times ended up with different identifiers.

So I created a proof of concept, dbpedialite, which uses Wikipedia PageIDs:
http://www.dbpedialite.org/things/87851
(At the time there was a page title edit war between Stoat and Ermine)


But now we have Wikidata – which solves this problem much better – so I should really get on and decommission dbpedialite.

What are you using Wikipedia Page IDs for? Might it be better to store the Wikidata ID and then lookup the Wikipedia page on demand?

Hoi,
It is indeed better to look up Wikipedia identifiers on demand. The
wikipedia articles associated with a Wikidata identifiers are a legacy.
Regularly Wikipedia articles are associated with different identifiers when
it is found that there is a mismatch between the different Wikipedia
article.. A good example; rose for the flower and rose for the plant..
Thanks,
GerardM

Hi Nick,

Please don't decommission dbpedialite, it does provide utility on other
fronts too :)

Could you elaborate? I was planning on turning dbpedialite into 301
redirects to Wikidata for a period of time before switching it off.

Nick,

dbpedialite provides a "best practices" demonstration for:

1. Linked Data Deployment -- i.e., it supports both content-negotiation
and metadata embedded in HTML deployment options

2. Bridging across DBpedia, Wikidata, and Wikipedia -- this also
provides value to DBpedia and Wikidata with regards to cross-reference
reconcilliation.

I believe the items above remain important :)

Yes, but "best practices" in a single place don't solve the problems
associated with mass appreciation and adoption. Basically, the more the
merrier!

Why? Because I don't believe in the power of one, with regards to a
Semantic Web of Linked Data.

Hi,

I have finally got around to starting to decommission dbpedialite.org
Pages now redirect to Wikidata entity URIs.

I won't be renewing the domain name when it expires 2019-05-09.
