In the lists of principals you can click on any principal to see the full detail for that record. These differences are more conceptual than actual, however: in the DAV specification they are really all 'principals' and all equal. Groups exist to simplify the maintenance of privileges.

Rather than assigning a write privilege to each individual with write access, you can create a group with the members being the people needing write access, and assign the write privilege to that group. In this way as people come and go you can maintain the members of the group and it is easier to see who has the desired level of access. If the needed level of access changes, you can change the grant to the individual group, rather than to each member of the group.

That's all way too complicated, even if it does need to be there under the covers. Suppose you have some resources, R1, R2 and R3 and you want to centralise the booking of the resources through an administrative assistant, A1.

When A1 is away you want to have a backup person, so you also want A2 to be able to do that. In a case like this you should create an intermediate group "G" and make each of the people you want to be able to administer those resources members of that group. Each of the resources should be set up to grant default privileges to everyone to see the full schedule read privilegeand the resources should be set up to grant write or possibly all privileges to the group "G".

In this case you might only set up a single principal for the resources, and have multiple calendars, one for each resource. P1 will be able to see all of the scheduled events for R1, R2 and R3, but will not be able to create, delete or modify them.

A1 and A2 will be able to see, create and modify all the events. In this case you should create a group "G", which all team members are members of, and each team member will grant whatever privileges they wish to that group. Similar to above, you should create a group "G", which all team members are members of, and each team member will grant write privileges to that group.

The DAViCal installation page has some further information on how to install and configure this application. Administration Functions The administration of this application should be fairly simple. Users, Resources and Groups These are the things which may have collections of calendar resources i. The primary differences between the types of principal are as follows: Users will probably have calendars, and are likely to also log on to the system. Resources do have calendars, but they will not usually log on.

Groups provide an intermediate linking to minimise administration overhead. They might not have calendars, and they will not usually log on. Groups Groups exist to simplify the maintenance of privileges. An administrative assistant has full access to a managers calendar In this case the manager will simply grant the desired specific privileges to their assistant.

A team wish to see each others calendars In this case you should create a group "G", which all team members are members of, and each team member will grant whatever privileges they wish to that group. The administrative interface has no facility for viewing or modifying calendar data.The response of this report will contain all the WebDAV properties and calendar object resource data specified in the request.

In the case of the CALDAV: calendar-data XML element, one can explicitly specify the calendar components and properties that should be returned in the calendar object resource data that matches the filter. For instance, a request to retrieve the value of a property that does not exist is an error and MUST be noted with a response XML element that contains a Not Found status value. For example, this condition might be triggered if a search specification would cause the return of an extremely large number of responses.

The iCalendar Validator provides developers and testers a method to validate their iCalendar feeds, which can take data from either a URL, file or text snippet and compare it against the RFC specification.

We believe we have one of the best iCalendar validation tools available on the internet. More information about the validator can be found here.Note that other groups may also distribute working documents as Internet-Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time.

This Internet-Draft will expire on January 19, All Rights Reserved. In the five years since WebDAV [3] was standardized, at least three groups have used WebDAV as a basis to provide Internet calendar access with a minimum of development effort.

However, each group decided independently how the calendaring data model would map to the WebDAV data model and how to deal with features such as recurrance and queries for free-busy times. This draft proposes a standard data model mapping and a few extensions to WebDAV that make WebDAV-server-based calendaring work well for clients while requiring a minimum of new work particularly on clients. This draft was commissioned at the Fall Minneapolis working group meeting of the CalSched working group.

However, those implementations do not interoperate because there are many small and big decisions to be made in how to model calendaring data as WebDAV resources and properties, as well as how to implement required features that aren't already part of WebDAV.

This draft is therefore intended to propose a standard way of modeling calendar data in WebDAV, plus some additional features to make calendaring work well.

WebDAV properties and other XML element names defined in this specification all use the "urn:ietf:params:xml:ns:calsch" namespace. Implementors may find occasion to define new WebDAV properties and other XML elements in implementing this specification, but this namespace is not intended for use in custom extensions. WebDAV offers a number of advantages as a framework or basis for calendar access.

Most of these advantages boil down to a significant reduction in design costs, implementation costs, interoperability test costs, deployment costs, and the cost of mistakes. Every new standard author or implementor finds certain small errors and the IETF spends considerable time and effort remediating these.

Some of the advantages are contingent upon the way WebDAV is used, which is why this section exploring advantages is inseparable from the rest of this document for the moment. This can make a lot of sense because it allows very simple calendar browsing clients to be written for devices that already have a HTTP stack: the client merely needs to download those calendar objects and be able to parse their formats. Since the iCalendar [1] formats are well-defined and well-supported, there's a natural choice for what resource to download for a granular calendar object.

Specifying new URL formats creates additional work for implementors of clients, servers and related applications that might see those URLs.

Dark Mode Beta - help us root out low-contrast and un-converted bits.If you use a calendar app to organize your life, you may have noticed that you can add a new event on your phone and it will be immediately updated to your desktop.

Likewise, your contacts can also be updated instantly across your devices whenever you make changes. The answer behind what is actually going on will depend on which system we are talking about, but some of the most common underlying protocols for syncing are CalDAV and CardDAV. You have a secretary who normally handles your scheduling, but you run into an old friend on the street.

You have a quick conversation and then, knowing that you have the night free, you agree to meet up that for dinner.

The problem? Just minutes before, your secretary had scheduled drinks with your superiors at the exact same time. When you see your secretary a little while later, you find out that you have been double-booked and face the difficult decision of either ditching your friend or skipping the business drinks, which could lead to numerous career opportunities.

Well, what if a current version of your schedule could be accessed at any time from anywhere? This is what CalDAV can give us. There is a range of other calendar systems that perform similar functions, but CalDAV is an interoperable standard that is now used in a range of calendar applications. Some of the most common clients that use the CalDAV standard include:. There is also a range of third-party applications that support CalDAV and make it easy to use on systems like Windows.

Our setup makes it simple for users to access, share and update their calendars across their devices. On top of this, our CalDAV solution also comes with our security-first approach. Your calendar is guarded by TLS and can only be accessed with your password, meaning that only authorized individuals have access to your data.

To understand CalDAV and how it can update in real-time, we have to think about where the calendar is actually stored. Is it stored on your computer? On your phone?

In the ether? Or is it somehow simultaneously stored everywhere? The answer is that your calendar is stored on a remote server. This provides a central hub that gives your devices up-to-date information.

If someone wants to schedule something on your calendar, they can perform queries to find when you have free time available. The owner of a particular calendar can set their own security levels, as well as nominate who can make changes to their calendar.

Since CalDAV is an interoperable standard, it can do this between organizations and across a range of different types of software. As you might have already guessed, CardDAV allows people to keep their address books and contact information updated in real-time and across all of their devices.

With CardDAV, you can alter the personal details of a contact on your phone and the same changes will be made on your computer, without you having to do anything else. Some of the most common clients that use the CardDAV standard include:. Once again, your address book is kept on a remote server. When updates are made from your phone or computer, the changes are put through to the server, which keeps all of your other devices in sync.

The CardDAV standard makes it much easier to keep your contacts in order and up-to-date. You must be connected or logged in to post a comment. This is to reduce spam comments.

Click Create projectenter a name, and click Create. To use the CalDAV interface, a client program initially connects with the calendar server at one of two starting points.

Where calid should be replaced by the "calendar ID" of the calendar to be accessed. This can be found through the Google Calendar web interface as follows: in the pull-down menu next to the calendar name, select Calendar Settings.

On the resulting page the calendar ID is shown in a section labelled Calendar Address. The calendar ID for a user's primary calendar is the same as that user's email address.

If a client program such as Mozilla Sunbird requires a calendar collection as the starting point, the URI to connect to is:. We recommend you transition to the new endpoint format described above.

Should I write my own SardineReport? I looks like I should end up with something like:. You can find a sample in RFC Section 7. I don't know Sardine, but yes, report sounds right. You can probably base yours on their SyncCollectionReport. Nothing extra required. I've implemented a report class which works, however, the result returned by Radicale seem to be incorrect.
