@Diigo

Please, what's new in version 3.1b508?

( http://groups.diigo.com/Diigo_HQ/forum/topic/42779 notes that use of parentheses is bugged ;)

http://groups.diigo.com/Diigo_HQ/forum/topic/4232 and other topics discuss PDF.

An appeal of PDF: it's relatively common, and plug-ins allow the format to viewed within some (not all) web browsers.

A downside, from a Diigo user perspective: I *guess* that ISO 19005-1:2005 PDF 1.4 (PDF/A-1) may be not well suited to rich/conversational annotations of the types that are desired by Diigo groups and individuals.

That probably steers any PDF-related possibilities in one or more of the following directions:

a) conversion to OpenDocument format (ODF)
b) conversion to Office Open XML (OOXML)
c) conversion to XHTML.

Diigo tendency towards HTML/XHTML might be balanced with other communities' tendency towards standards-based annotation of ODF and OOXML.

+1 to simplicity and speed

Still, Diigolet could be improved (as suggested in many/varied topics).

Rule of thumb: anything that is not immediately present or easy in Diigolet should be easy in the web interfaces to Diigo.

@ Diigo

Sorry, this may be a duplicate of a previously reported bug,
http://groups.diigo.com/Diigo_HQ/forum/topic/41040

http://www.diigo.com/tools/export export (of all) to Netscape bookmark format includes tag, if that helps.

Alternatively, make your selection then extract annotations; the resulting HTML includes the bookmarks.

What's the ultimate aim?

There was a similar discussion a few days ago,
http://groups.diigo.com/Diigo_HQ/forum/topic/broken-links-41934

Using the same combination of software, and bookmarking this topic, I can't reproduce the issue:



Please, can you offer an example of an affected URL?

> Selecting "don't show annotations" … should not mask that a page
> is bookmarked.

That suggestion seems reasonable.

Well done for pinpointing the issue…

This is very different from a calendar (timeline) in relation to when you bookmarked something. Diigo V3 beta does not offer to-do function to users of Diigo.

Subject: calendars

If you wish for a web-based system that supports VTODO, I can recommend Chandler Hub.

Keyword: VALARM

If you want an alarm in relation to a Diigo bookmark, you can:

1. in Diigo: get annotated link, copy

2. in Chandler Hub, or in any other service that supports VTODO and VALARM: paste.

For a VTODO: the default participation status is NEEDS-ACTION.

Do you wish for a reminder (VALARM) in RSS to read only once?

Or do you wish for repeated reminders, until the participation status of a VTODO is changed (from NEEDS-ACTION) to ACCEPTED, IN-PROCESS or COMPLETED?

I imagine a teacher highlighting sentences that suit a particular level of expertise.

For an early part of a course: the teacher (with or without a Diigo Educator Account) might use a private Diigo list, or a Diigo group, to draw attention to sentences that suit less expertise.

For the later parts of a course: the teacher might draw attention to sentences that suit greater expertise.


Subject: colours/levels of Diigo highlights

Discussions of colours include:
http://groups.diigo.com/Diigo_HQ/forum/topic/144
http://groups.diigo.com/Diigo_HQ/forum/topic/2558

I can not imagine layers/levels of highlighting.

IMHO highlighting in Diigo should be as simple as possible, as close as possible to the reality of drawing a highlighter pen across a sheet of paper.

To a single level of highlight, you can stick multiple groups of notes.


Hope that helps,

Regards
Graham
