NAME
slp.reg - SLP static registration file
SYNOPSIS
/etc/slp.reg
DESCRIPTION
The /etc/slp.reg file provides a mechanism for old applications which are not SLP enabled and cannot
be converted, and for portably exchanging registrations between SLP implementations.
This file contains a list of service registrations that are read by slpd at startup time and advertised later by
slpd which can be acting either as the service agent server or the directory agent.
The character encoding of the registrations is required to be UTF-8.
The syntax of the serialized registration file, in ABNF format [5], is as follows:
ser-file = reg-list
reg-list = reg / reg reg-list
reg = creg / ser-reg
creg = comment-line ser-reg
comment-line = ( "#" / ";" ) 1*allchar newline
ser-reg = url-props [slist] [attr-list] newline
url-props = surl "," lang "," ltime [ "," type ] newline
surl = ;The registration’s URL. See
; [8] for syntax.
lang = 1*8ALPHA [ "-" 1*8ALPHA ]
;RFC 1766 Language Tag see [6].
ltime = 1*5DIGIT
; A positive 16-bit integer
; giving the lifetime
; of the registration.
type = ; The service type name, see [7]
; and [8] for syntax.
slist = "scopes" "=" scope-list newline
scope-list = scope-name / scope-name "," scope-list
scope = ; See grammar of [7] for
; scope-name syntax.
attr-list = attr-def / attr-def attr-list
attr-def = ( attr / keyword ) newline
keyword = attr-id
attr = attr-id "=" attr-val-list
attr-id = ;Attribute id, see [7] for syntax.
attr-val-list = attr-val / attr-val "," attr-val-list
attr-val = ;Attribute value, see [7] for syntax.
allchar = char / WSP
char = DIGIT / ALPHA / other
other = %x21-%x2f / %x3a-%x40 /
%x5b-%x60 / %7b-%7e
; All printable, nonwhitespace US-ASCII
; characters.
newline = CR / ( CRLF )
The syntax for scope names, attribute tags, and attribute values requires escapes for special characters.
DAs and SA servers that process serialized registrations must handle them exactly as if they were
registered by an SA. In the url-props production, the type token is optional. If the type token is present
for a service:URL, a warning is signaled and the type name is ignored. If the maximum lifetime ltime is
specified (65535 sec.), the registration is taken to be permanent, and is continually refreshed by the DA or
SA server until it exits.
Scopes can be included in a registration by including an attribute definition with tag "scopes" followed by a
comma separated list of scope names immediately after the url-props production. If the optional scope list
is present, the registrations are made in the indicated scopes. Otherwise, they are registered in the scopes
with which the DA or SA server was configured through the net.slp.useScopes property.
