NAME
dacs.services - DACS web services
SYNOPSIS
dacswebservice [dacsoptions[1]]
DESCRIPTION
These web services are part of the DACS suite.
The following is a list of DACS web services with a brief description of each. General aspects of DACS and its web services are discussed
in dacs(1)[2]. Individual web services are discussed in more detail elsewhere. By default, these CGI programs are installed in the dacs
subdirectory of the Apache cgi-bin directory.
By convention, DACS web service names use underscores as word separators. Some web services have command counterparts; their names omit the
underscores.
o
dacs_admin
A low-level administration tool for DACS.

o
dacs_auth_agent
Authenticate by delegating responsibility to a trusted identity.

Each one implements a particular authentication method and optionally
returns role information.

Standard CGI Arguments for DACS Web Services
The following set of CGI arguments are recognized by most DACS web services. When the document for a DACS web service says that it accepts
"the standard CGI arguments", it is referring to the following arguments; not all of these arguments are necessarily meaningful to all web
services, however.
In general, duplicate CGI argument names are not allowed; i.e., you cannot pass an argument named DACS_JURISDICTION more than once when
calling a DACS web service, even if each occurrence of the argument has the same value.
DACS_JURISDICTION
This argument is required by most web services. It specifies the name of the jurisdiction to which the request is being sent. Web
services will verify that the jurisdiction that receives the request is the same as the intended recipient.
DACS_VERSION
If this argument is present, it specifies the major DACS version number (e.g., 1.4) expected by the client. The service request will
fail if the DACS software does not support this version number. If not provided, no compatibility checks are performed.
FILE
Reserved for future use for file uploading. Requests content type application/x-dacs-credentials.
FORMAT
This optional argument requests a particular output format. The default value varies, but it is usually HTML. Not all formats are
supported by every web service; refer to the manual page for details. The following values are recognized:
HTML
Requests content type text/html;
JSON
Requests content type application/json (JavaScript Object Notation, see www.json.org[16] and RFC 4627[17]);
PHP
Used by the dacs_list_jurisdictions(8)[10] web service when its output is to processed by PHP;
PLAIN
Requests content type text/plain;
TEXT
Like PLAIN except that no content type is specified;
XML
Requests content type text/xml. If the DTD_BASE_URL directive is configured, a DOCTYPE element with the keyword SYSTEM followed by
a value derived from DTD_BASE_URL is emitted; e.g.,
<!DOCTYPE foo SYSTEM "http://fedroot.com/dacs/dtd-xsd/foo.dtd">
If DTD_BASE_URL is not configured, an internal DTD is emitted. A default xmlns attribute is emitted in both cases;
XMLDTD
Requests content type text/xml This emits an internal DTD and default xmlns attribute;
XMLSCHEMA
Requests content type text/xml. If the XSD_BASE_URL directive is configured, xmlns:xsi and xsi:schemaLocation attributes are
emitted, the former having a compile-time value (e.g., "http://www.w3.org/2001/XMLSchema-instance") and the latter being a pair,
the first having the same value as the value of the xmlns attribute and the second having a value derived from XSD_BASE_URL; e.g.,
<foo xmlns="http://fedroot.com/dacs/v1.4"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://fedroot.com/dacs/v1.4
http://amd.dss.bc.ca/dacs/dtd-xsd/foo.xsd">
The default xmlns attribute is also emitted. If XSD_BASE_URL is not configured, only the default xmlns attribute is emitted; and
XMLSIMPLE
Requests content type text/xml Neither a DTD (no DOCTYPE) nor a default xmlns attribute is emitted.
Also see the -format[18] command line flag (one of the dacsoptions[1]).
DIAGNOSTICS
Programs usually exit 0 if everything was fine, 1 if an error occurred.
