Nadja,
"Why is the topic map standard at http://www.topicmaps.org/standards/ an unofficial topic map standard?" Links can be found to working technical committee reports, which are generally re-titled as "standards" once voted and accepted by ISO. These TC reports vary little from what is published by the ISO community as a "standard".
"ISO/IEC 19788-1:2011 is information-technology-neutral" means that information elements defined by the standard for learning resources can be represented using a concrete implementation syntax such as provided by the RDF or by Topic Maps or by SMW syntax or by JSON or by a variety of others. For instance, a data element defined by 19788 might be "Learning Resource" which has an attribute called "Minimum Education Level".
In RDF a given LearningResource would be exchanged via
<rdf:RDF xmlns:iso="http://iso.org/19788/" xmlns:dc="dublin core">
<iso:LearningResource rdf:about="LR12345">
<dc:title>Lithium</dc:title>
<iso:minEducLevel>12th grade</iso:minEducLevel>
</iso:LearningResource>
</rdf:RDF>
The owl:Class definition for iso:LearningResource and rdf:Property definition for iso:minEducLevel are not shown.
In Topic Maps, exchange is had from
<tm:topicmap xmlns:tm="http://iso.org/13250/" xmlns:dc="dublin core">
<tm:topic>
<tm:itemIdentity>LR12345</tm:itemIdentity>
<tm:name>
<tm:value>Lithium</tm:value>
</tm:name>
<tm:occurrence>
<tm:type>
<tm:resourceRef href="http://iso.org/19788/MinimumEducationLevel"/>
</tm:type>
<tm:resourceData>12th grade</tm:resourceData>
</tm:occurrence>
</tm:topic>
</tm:topicmap>
Markup for a "published subject identifier" -- eg http://iso.org/19788/MinimumEducationLevel -- is not shown.
In SMW, the page named "Lithium" might be exported as
<page>
<title>Lithium</title>
<revision>
<text xml:space="preserve">
[[Category:ISO 19788 Learning Resources]]
[[minEducLevel::12th grade]]
</text>
</revision>
</page>
while a page entitled "Category:ISO 19788 Learning Resources" is mapped elsewhere in the wiki to an import-able owl:Class definition and a page entitled "Property:minEducLevel" is mapped to an import-able rdf:Property definition.
It'd be interesting to hear from the Wikidata team what the SNAK API serialization(s) would be.

You provided a nice link to unofficial topic map standards, thank you. Here's others: http://www.garshol.priv.no/download/tmlinks.html."
They talk about that it is ISO 13250 standard.
You had drawn my attention to the ISO, thanks for that however the impression that they might have some standards is from their
where they write amongst others:
"The primary purpose of ISO/IEC 19788 is to specify metadata elements and their attributes for the description of learning resources. This includes the rules governing the identification of data elements and the specification of their attributes."
since this thing costs 162 CHF i can't check what those guys are really doing there, however it would be strange to define
metadata which is not for automated processing. In particular they write a little later:
"ISO/IEC 19788-1:2011 is information-technology-neutral and defines a set of common approaches, i.e. methodologies and constructs, which apply to the development of the subsequent parts of ISO/IEC 19788."
would they write this if ISO/IEC 19788 was information-technology-neutral as well?
moreover there exists also a
but where the word AUTOMATED appears explicitly.
but of course it would be nicer to have someone who knows explicitly what exactly they are having in mind there at ISO.
