Notes on the SLinkS RDF schema, as I read it:

version 0.99       10/26/99 

nice, friendly license!

pointer to http://www.w3.org/TR/REC-rdf-syntax-19990222 is faulty; the
address of the RDF REC is

<rdf:Property ID="template">

hmm... odd; http://www.openly.com/slinks/slinks.dtd is an RDF class?
I guess you can use it that way; is that what you meant?

Interesting idiom: using foo.dtd to denote the RDF class consisting
documents that validate per foo.dtd.

<rdf:Property ID="restriction">
        <rdfs:comment>restrictions are indications by a Linkee that the
modified Link Method may only be used under specific conditions
specified here.
The specifications have legal definitions available at
http://www.openly.com/SLinkS/legal.html </rdfs:comment>

Er.. I don't like to see URIs lost (to the RDF parser) in plain text.
I wonder if you can use the RDF(s?) seeAlso property?

<rdfs:Class ID="MIME-Type">
        <rdfs:comment>These are the allowed MIME-types.</rdfs:comment>
        <MIME-Type ID="text-html">

I recommend, in stead, that you allow any resource as a MIME type,
and note that those those that start with:


have been registered with IANA; for example:


I guess you could spell this in RDF as:


	rdf:type="#MIME-Type" />

or, equivalently (I think):



<rdfs:Class ID="WebServiceType">
        <rdfs:comment>The allowed web service type. Only one type should
specified. Default is OnLineAccess.</rdfs:comment>
        <rdfs:label>WEB SERVICE TYPE</rdfs:label>

        <WebServiceType ID="OnLineAccess">
                <rdfs:comment>This Web Service provides "on-line" access
to a
citeable resource, or aggregates online access.</rdfs:comment>
                <rdfs:label>On-Line Access</rdfs:label>

I thin you meant to enumerate some instances of the class
but what you've done is to give some (odd looking) properties of

i.e. it says:

	#WebServiceType --- #WebServiceType --> #OnLineAccess

but I think what you meant was:

	#OnLineAccess --- rdfs:type ---> #WebServiceType

To say what you mean, close the <rdfs:Class ID="WebServiceType">...
element before you start the enumeration.
similarly for your enumeration of subjects.

regarding <rdf:Property ID="title">; you should probably note that
it's a subPropertyType of the dublin core title.
