Hi Francois,

I hope you haven’t done that yet as I just found some more small errors.

In Example 23 PCBoard2 and PCBoard3 should read:

<PCBBoard2> a ssn:System , sosa:Platform ;
  rdfs:label "PCB Board 2"@en ;
  rdfs:comment "PCB Board 2 hosts DHT22 temperature and humidity sensor #4579 permanently, one can say it has it as one of its subsystems."@en ;
  sosa:hosts <DHT22/4579> ;
  ssn:hasSubSystem <DHT22/4579> .

<PCBBoard3> a ssn:System , sosa:Platform ;
  rdfs:label "PCB Board 3"@en ;
  rdfs:comment "PCB Board 3 hosts DHT22 temperature and humidity sensor #4580 permanently, one can say it has it as one of its subsystems."@en ;
  sosa:hosts <DHT22/4580> ;
  ssn:hasSubSystem <DHT22/4580> .

Thanks,
Armin

    Hi,
    
    As mentioned during Wednesday's plenary call, a few broken links, listed below, have been identified (thanks Kerry for pointing them out!) in the SSN Ontology Recommendation. Good news is our "In-place modification of W3C Technical Reports" policy [1] makes it possible to incorporate fixes to the published version without re-publishing a new document, so I am planning to do that on Tuesday next week.
    
    The problems are:
    
    1. In Section 5.1 [2], the link to the ontology graph should be to:
     http://www.w3.org/ns/ssn/systems/

    ... as stated in the previous paragraph, and not to:
     http://www.w3.org/ns/ssn/System

    ... which does not exist in practice.
    
    2. In Section 6.5.1 [3], the table asserts that the namespace for the SOSA to PROV alignment ontology is:
     http://www.w3.org/ns/sosa/prov/

    ... which is correct, but the link is to:
     http://www.w3.org/ns/prov-o

    ... which is clearly incorrect.
    
    3. In section B.11 [4], the link to the graph should be to the IP68.ttl file, and not to the dht22-deployment-sosa.ttl file (which is the graph for the example in B.10).
    
    Another typo was noted in B.5 [5] (see issue #979 on GitHub [6]). The final ";" in the example in Turtle should rather be a ".". No matter how benign this change may seem, I cannot fix it in the published document, so this would have to be published as an erratum next to the spec. Let's run that process separately.
    
    Back to broken links, to avoid having to do these sort of modifications multiple times, now would be a good time to report on other wrong links in the spec! So, please all take a moment to go through the specification one more time, just in case...
    
    Thanks,
    Francois.
