DAS/2 Validation Service
About
The DAS/2 NIH grant included funding for the development of a validation service to verify conformance of DAS/2 clients and servers with the DAS/2 specification. This should promote consistency between different implementations and thereby enhance interoperability of DAS/2 based systems.
Server URL
HTTP Interface:
http://cgi.biodas.org:8080/validate_url?url=http://example.com
If the validator is down, please notify the discussion list.
Usage Information
This information pertains to the HTTP interface and was originally provided by Andrew Dalke on the DAS/2 discussion list: http://lists.open-bio.org/pipermail/das2/2006-October/000863.html.
Parameter: url
Parameter "url" is required. This is the URL to validate.
%curl 'http://cgi.biodas.org:8080/validate_url?url=http://slashdot.org/' <?xml version="1.0" encoding="utf-8"?> <DAS_VALIDATION url="http://slashdot.org/"> <MESSAGE text="Unknown Content-Type 'text/html'." severity="error" /> <MESSAGE text="expat: mismatched tag at byte 1794, line 29, column 3" severity="fatal" /> </DAS_VALIDATION>
Parameter: doctype
It has an optional parameter "doctype" which is the document type to expect
%curl 'http://cgi.biodas.org:8080/validate_url?url=http://das.biopackages.net/das/genome/human/;doctype=sources' <?xml version="1.0" encoding="utf-8"?> <DAS_VALIDATION url="http://das.biopackages.net/das/genome/human/" doctype="sources" />
In that last case there were no messages.
The XML document is
<DAS_VALIDATION url="URL-used-for-the-validation"
doctype="the-document-type"? >
<MESSAGE severity="one of info, warning, error, fatal"
text="the error message" /> *
</DAS_VALIDATION>
A note about the doctype. If the server could not get the document then the validation will not have a doctype even if you gave it one.
%curl 'http://cgi.biodas.org:8080/validate_url?url=http://slashdot.org;doctype=types' <?xml version="1.0" encoding="utf-8"?> <DAS_VALIDATION url="http://slashdot.org"> <MESSAGE text="Received Content-Type 'text/html', expected 'application/x-das-types+xml'." severity="fatal" /> <MESSAGE text="expat: mismatched tag at byte 1794, line 29, column 3" severity="fatal" /> </DAS_VALIDATION>
If you tell it the wrong doctype and it gets something in XML then it assumes the reponse is in the given doctype
%curl 'http://cgi.biodas.org:8080/validate_url?url=http://das.biopackages.net/das/genome/human/;doctype=types'
<?xml version="1.0" encoding="utf-8"?>
<DAS_VALIDATION url="http://das.biopackages.net/das/genome/human/"
doctype="types">
<MESSAGE text="Received Content-Type 'application/x-das-sources+xml',
expected 'application/x-das-types+xml'." severity="fatal" />
<MESSAGE text="Expected element
'{http://biodas.org/documents/das2}TYPES' but got
'{http://biodas.org/documents/das2}SOURCES' at byte 41, line 3, column
2" severity="fatal" />
<MESSAGE text="element "SOURCES" from namespace
"http://biodas.org/documents/das2" not allowed in this
context at byte 41, line 3, column 2" severity="error" />
If no input doctype is given then it will guess at the doctype based on analysis of what it got from the remote server
%curl 'http://cgi.biodas.org:8080/validate_url?url=http://das.biopackages.net/das/genome/human/' <?xml version="1.0" encoding="utf-8"?> <DAS_VALIDATION url="http://das.biopackages.net/das/genome/human/" doctype="sources"> <MESSAGE text="Assuming doctype of 'sources' based on Content-Type" severity="info" /> </DAS_VALIDATION>
This XML should be easy for anyone to parse.
