Scope
|
|
\layout Standard
|
|
|
|
As many different opensource and freesoftware groupware systems are being
|
|
developed, the full realization of the dream of a connected world should
|
|
be prefaced by an agreement to interoperate.
|
|
There are limited ways in which cooperation with these and commercial groupware
|
|
systems may be achecived, the majority if not all of which were derived
|
|
via the establishment of open standards.
|
|
These might include email (POP3/IMAP), contacts(LDAP,vcard), or scheduling(ical
|
|
/vcal).
|
|
It is felt that while these have proven themselves to be very useful, they
|
|
are insufficient to satisfy the real needs of a typical business environment.
|
|
\layout Standard
|
|
|
|
This document hopes to provide a reasonable, if limited, recommendation
|
|
for a set of standardized methods to be used for groupware services interaction.
|
|
More specifically, it hopes to address the need for such a standard as
|
|
well as to spur discussion about the common service names and methods themselve
|
|
s.
|
|
\layout Standard
|
|
|
|
Examples will be given for implementations in XML-RPC, since this standard
|
|
is relatively fixed and open.
|
|
\layout Standard
|
|
|
|
This document does not provide recommendations for the underlying access
|
|
control system which would allow or deny a particular action.
|
|
\layout Standard
|
|
|
|
Also not discussed here is login and authorization to be used for initial
|
|
access to a service provider.

The Services

|
Overview
|
|
\layout Standard
|
|
|
|
There are a few common services types that will be needed for minimum useability
|
|
of a groupware server or application.
|
|
They are:
|
|
\layout Itemize
|
|
|
|
Contacts
|
|
\layout Itemize
|
|
|
|
Schedule
|
|
\layout Itemize
|
|
|
|
Notes
|
|
\layout Itemize
|
|
|
|
Todo
|
|
\layout Standard
|
|
|
|
These services are represented already in places such as existing groupware
|
|
client-server applications and also in the PalmOS basic-4 buttons and applicati
|
|
ons.
|
|
Different systems may have different names for these services internally,
|
|
e.g.
|
|
Contacts - addresses, addressbook, people, Schedule - calendar, agenda,
|
|
meetings.
|
|
\layout Standard
|
|
|
|
Within each of these services are some common methods that would be called
|
|
to store, retreive, or update data:
|
|
\layout Itemize
|
|
|
|
read_list
|
|
\layout Itemize
|
|
|
|
read
|
|
\layout Itemize
|
|
|
|
save
|
|
\layout Itemize
|
|
|
|
delete
|

Detail
|
|
\layout Subsubsection
|
|
|
|
Contacts
|
|
\layout Standard
|
|
|
|
The concept of contacts may encompass local addressbooks, LDAP, and lists
|
|
stored in other media.
|
|
The purpose of the contacts service is not to duplicate or attempt to replace
|
|
these.
|
|
In some respects, it might do just that.
|
|
But its goal is more so to provide a common and shareable way for the other
|
|
core services to create, edit, and read a common user and address list.
|
|
All of the other services may use the contact service to obtain record
|
|
owner information to be used in access control.
|
|
They would also use them when it is required to share this data, as with
|
|
a meeting where other local and non-local users will be invited to attend.
|
|
\layout Standard
|
|
|
|
Contacts may include the local installed user base, users on other cooperative
|
|
servers, or email addresses used for limited cooperation with other groupware
|
|
services that are not compliant with this service scheme or implementations
|
|
thereof.
|
|
It could also include individuals using web-based or local ISP email services.
|
|
The scope of this document, however, is to define the service with regard
|
|
to the common methods to be used for server-server and client-server communicat
|
|
ions:
|
|
\layout Itemize
|
|
|
|
read_list
|
|
\layout Standard
|
|
|
|
This method is used to list contacts, with or without limits, filters, or
|
|
search criteria.
|
|
In this way it can be used for simple lists or to search for contact records
|
|
and their identifiers.
|
|
The optional search criteria includes:
|
|
\layout Enumerate
|
|
|
|
start - Start at this identifier (integer: default 0)
|
|
\layout Enumerate
|
|
|
|
limit - Limit to this number of records returned(integer: unlimited by default)
|
|
\layout Enumerate
|
|
|
|
fieldlist - limit to showing only these fields (array: default to identifier,
|
|
owner identifier, possibly firstname and lastname)
|
|
\layout Enumerate
|
|
|
|
filter - Show records that are public or private only, or other system-specific
|
|
filters, e.g group or company(string: default '')
|
|
\layout Enumerate
|
|
|
|
query - Search internal fieldlist for a value (string: default '')
|
|
\layout Standard
|
|
|
|
The return for this method includes:
|
|
\layout Enumerate
|
|
|
|
count of number of records returned(integer)
|
|
\layout Enumerate
|
|
|
|
array consisting of: array: identifier => (array: fieldlist key => value
|
|
pairs)
|
|
\layout Itemize
|
|
|
|
read
|
|
\layout Standard
|
|
|
|
Once the identifier for a single contact record is known, the contact may
|
|
be read for more detail using this method.
|
|
This takes two parameters:
|
|
\layout Enumerate
|
|
|
|
identifier - (integer: no default)
|
|
\layout Enumerate
|
|
|
|
fieldlist - limit to showing only these fields (array: default to identifier,
|
|
owner identifier, possibly firstname and lastname)
|
|
\layout Standard
|
|
|
|
And returns:
|
|
\layout Enumerate
|
|
|
|
array consisting of: array: identifier => (array: fieldlist key => value
|
|
pairs)
|
|
\layout Itemize
|
|
|
|
save
|
|
\layout Standard
|
|
|
|
This is a method used to save an existing record or create a new one.
|
|
If the identifier for an existing record is not passed, a new entry will
|
|
be created.
|
|
\layout Itemize
|
|
|
|
delete
|
|
\layout Standard
|
|
|
|
This will allow deletion of a record by passing its identifier.

Examples in XML-RPC
|
|
\layout Standard
|
|
|
|
Query the contacts service for read_list, using only start and limit to
|
|
grab the first 5 records, starting with identifier 1.
|
|
Additionally, return only the firstname and lastname fields n_given and
|
|
n_family (firstname and lastname in pseudo vcard format):
