As per 5545, URL is meant to be a pointer to an alternative representation ("more dynamic rendition") of the event - e.g., it could be a web page with details of the event. SOURCE, on the other hand, is meant to be a pointer to the original location where the iCalendar data itself was retrieved from. I could add the following sentence to the SOURCE property description to help clarify the differences: Note that the URL property (Section 3.8.4.6 of [RFC5545]) defines a URL for an alternative representation of the calendar information (which could take the form of a web page, or an image, etc), whereas the SOURCE property is used to refer to the location where updated iCalendar data can be found. -- Cyrus Daboo From nobody Tue Apr 7 11:59:05 2015 Return-Path: X-Original-To: calsify@ietfa.amsl.com Delivered-To: calsify@ietfa.amsl.com Received: from localhost (ietfa.amsl.com [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id A0F421B3A6C for ; Tue, 7 Apr 2015 11:59:03 -0700 (PDT) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -4.21 X-Spam-Level: X-Spam-Status: No, score=-4.21 tagged_above=-999 required=5 tests=[BAYES_00=-1.9, RCVD_IN_DNSWL_MED=-2.3, T_RP_MATCHES_RCVD=-0.01] autolearn=ham Received: from mail.ietf.org ([4.31.198.44]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id r7KIP2pIqg67 for ; Tue, 7 Apr 2015 11:58:53 -0700 (PDT) Received: from smtp.andrew.cmu.edu (SMTP.ANDREW.CMU.EDU [128.2.157.39]) (using TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 bits)) (No client certificate requested) by ietfa.amsl.com (Postfix) with ESMTPS id 506461A90A3 for ; Tue, 7 Apr 2015 11:58:53 -0700 (PDT) Received: from localhost.localdomain (cpe-76-180-151-43.buffalo.res.rr.com [76.180.151.43]) (user=murch mech=PLAIN (0 bits)) by smtp.andrew.cmu.edu (8.14.8/8.14.8) with ESMTP id t37Iwi6S027255 (version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-SHA bits=256 verify=NOT); Tue, 7 Apr 2015 14:58:45 -0400 Message-ID: <552428E4.9040504@andrew.cmu.edu> Date: Tue, 07 Apr 2015 14:58:44 -0400 From: Ken Murchison Organization: Carnegie Mellon University User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:24.0) Gecko/20100101 Thunderbird/24.2.0 MIME-Version: 1.0 To: Cyrus Daboo , Calsify References: <5524223E.1050607@andrew.cmu.edu> In-Reply-To: Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit X-PMX-Version: 6.0.3.2322014, Antispam-Engine: 2.7.2.2107409, Antispam-Data: 2015.4.7.185118 X-SMTP-Spam-Clean: 28% ( SXL_IP_DYNAMIC 3, HTML_00_01 0.05, HTML_00_10 0.05, BODYTEXTP_SIZE_3000_LESS 0, BODY_SIZE_1300_1399 0, BODY_SIZE_2000_LESS 0, BODY_SIZE_5000_LESS 0, BODY_SIZE_7000_LESS 0, DATE_TZ_NA 0, FROM_EDU_TLD 0, RDNS_GENERIC_POOLED 0, RDNS_POOLED 0, RDNS_RESIDENTIAL 0, RDNS_SUSP 0, RDNS_SUSP_GENERIC 0, RDNS_SUSP_SPECIFIC 0, REFERENCES 0, __ANY_URI 0, __BOUNCE_CHALLENGE_SUBJ 0, __BOUNCE_NDR_SUBJ_EXEMPT 0, __CP_MEDIA_BODY 0, __CP_NOT_1 0, __CT 0, __CTE 0, __CT_TEXT_PLAIN 0, __FORWARDED_MSG 0, __HAS_FROM 0, __HAS_MSGID 0, __IN_REP_TO 0, __MIME_TEXT_ONLY 0, __MIME_VERSION 0, __MOZILLA_MSGID 0, __MOZILLA_USER_AGENT 0, __PHISH_PHRASE1_B 0, __PHISH_SPEAR_STRUCTURE_1 0, __RDNS_POOLED_1 0, __REFERENCES 0, __SANE_MSGID 0, __SUBJ_ALPHA_NEGATE 0, __TO_MALFORMED_2 0, __URI_NO_PATH 0, __URI_NO_WWW 0, __URI_NS , __USER_AGENT 0) X-SMTP-Spam-Score: 28% X-Scanned-By: MIMEDefang 2.74 on 128.2.157.39 Archived-At: Subject: Re: [calsify] draft-ietf-calext-extensions-00 X-BeenThere: calsify@ietf.org X-Mailman-Version: 2.1.15 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 07 Apr 2015 18:59:03 -0000 On 04/07/2015 02:50 PM, Cyrus Daboo wrote: > Hi Ken, > > --On April 7, 2015 at 2:30:22 PM -0400 Ken Murchison > wrote: > >> This all looks pretty straightforward to me and I will add/update >> support >> for these properties and parameters to libical once we come to consensus >> on the draft. >> >> However, I am somewhat unclear on the distinction between URL and >> SOURCE. > > As per 5545, URL is meant to be a pointer to an alternative > representation ("more dynamic rendition") of the event - e.g., it > could be a web page with details of the event.

A few comments: - The current text in Section 4 leaves me unclear as to whether the ordering of VAVAILABILITY components by priority means that the expected order is: 0, 1, 2, ... , 8, 9 OR 0, 9, 8, ... , 2, 1 - The text in Section 5.1.1 (available 8:00AM to 6:00PM, 2 hr event) doesn't match the iCalendar data in Appendix A (available 9:00AM to 6:00PM, 1 hr event) - I'd suggest fixing the iCalendar data to match the text since the table in 5.1.1 uses 2 hr blocks of time on even hours - Since VAVAILABILITY components can be stored in calendar collections, do we need to add a section that discusses how it behaves with CALDAV:time-range? Perhaps a new Section 6.2.x such as the following: Section 9.9 of [RFC4791] describes how to specify time ranges to limit the set of calendar components returned by the server. This specification extends [RFC4791] to describe how to apply time range filtering to VAVAILABILITY components. A VAVAILABILITY component is said to overlap a given time range if the condition for the corresponding component state specified in the table below is satisfied. The conditions depend on the presence of the DTSTART, DTEND, and DURATION properties in the AVAILABILITY component. Note that, as specified above, the DTEND value MUST be a DATE-TIME value equal to or after the DTSTART value if specified. +------------------------------------------------------------+ | VAVAILABILITY has the DTSTART property? | | +--------------------------------------------------------+ | | VAVAILABILITY has the DTEND property? | | | +----------------------------------------------------+ | | | VAVAILABILITY has the DURATION property? | | | | +------------------------------------------------+ | | | | Condition to evaluate | +---+---+---+------------------------------------------------+ | Y | Y | N | (start < DTEND AND end > DTSTART) | +---+---+---+------------------------------------------------+ | Y | N | Y | (start < DTSTART+DURATION AND end > DTSTART) | +---+---+---+------------------------------------------------+ | Y | N | N | (end > DTSTART) | +---+---+---+------------------------------------------------+ | N | Y | N | (start < DTEND) | +---+---+---+------------------------------------------------+ | N | N | * | TRUE | +---+---+---+------------------------------------------------+ -- Kenneth Murchison Principal Systems Software Engineer Carnegie Mellon University
