Errors found in main Ontology data (which will be displayed at catalog.caida.org):

  1. Some classes have properties of type 'Url' from schema.org, which is not a real type, should be either 'url' or 'URL'
    → PropertyMap has propertyUrl (Url) and namespaceUrl (Url)
    → NamespaceProperty has classUrl (Url) and propertyUrl (Url)

  2. Description for AsnLinkRelationshipNamespace:
    Although business agreements between ISPs can be complicated, the original model introduced by Gao abstracts business relationships into the following three most common types: Customer ASN0 [is a the] customer of ASN1, Provider ASN1 is the provider of ASN1, Peer ASN1 and ASN2 are peers, and [Silbing] ASN1 and ASN2 are siblings.

  3. Description for AsnNumberNamespace:
    An autonomous system is a collection of connected Internet Protocol routing prefixes under the control of one or more network operators on behalf of a single administrative entity or domain, that presents a common and clearly defined routing policy to the Internet. Until 2007, AS numbers were 16-bit unsigned integers with a range from 0 to 65,536. In 2007, AS numbers were [expaned] to 32-bit unsigned integers creating a theoretical range from 0 to 4,294,967,295. This range is contrasted by a set of reserved blocks, limiting the set of available AS numbers.
