In the following text we want to present some of the different concepts for annotations, notes and comments which are present on the web.
We will briefly analyze the different setups, scopes and possibilties each solution offers.
We will also add some uses cases by the example of a fictional professor Brunelleschi who is using these tools at work in his institute and for himself.
But first of all, we need to set some things straight – first of all the terminology. In fact there are three fundamentally different ways to relate an information to a given resource available today:
|Annotating||which is adding a note to a line of text|
|Commenting||which is adding a note to a website (mostly a post)|
|Note taking||which is taking a note about a website|
These meta-informations can have different scopes (or endpoints):
|Site-Specific||when notes, annotations and comments can relate to one specific web site only|
|Any Web Page, if Provided by Web Site Owner||when notes, annotations and comments can relate to all websites where its owner has installed a specific script|
|Any Web Page||when notes, annotations and comments can relate to any website|
And finally, there are different places where these meta-informations are stored:
|Server provided by Web Site||when notes, annotations and comments reside on a server provided by the owner of the web site|
|Server provided by Third-Party||when notes, annotations and comments reside on a third-party server, probably chosen by the user (free/open source or commercial offering)|
We will now describe the most common cases in more detail.
1. Site-Specific Commenting
Our professor Brunelleschi browses through the websites searching for some place to spend the holidays – it’s August, after all – when he comes upon a museum’s website where one of the artefacts is falsely presented as the work of one of his colleagues. And even as the work of one of his arch enemies!
Brunelleschi is really angry, but a bit undecided about what he should do: he could contact the museum staff, but right now, in mid August, there is zero probability that someone – and even less a knowledgable person – will answer his email. And he doesn’t want to end up dealing with disgruntled staff telling him he should try again later.
But then he sees that there’s a possibility to leave comments on the web sites: he decides to write a comment about the falsely attributed authorship. But wait – should he use his real name? Probably not, better avoid to give his enemies a pretext for denouncing him as petty and arrogant.
At the end Brunelleschi writes his comment using the pseudonym »Giovannino«.
Overview: Commenting is for leaving short messages regarding a blog post or web site. It might even be anonymous, even if you are forced to register with an email. The comment is not necessarily traceable to yourself, nor will it be part of your work material.
Target: The comment function works only on specially prepared web sites, like blogs.
Functions: Sharing the comment is only indirectly possible, by sending others a link to the whole website. Sometimes a function like “Inform me if someone replys to my post” is available. Replying to a comment is definitely possible. Tagging is mostly available.
Requirements: On the user side, mostly some kind of login is required to avoid automaized spam. Web site owners instead need to setup their site to allow commenting (and sometimes need to approve comments).
Storage: Comments are stored at the specific web site.There is no export functionality.
Reuse: Reuse is not foreseen.
Available services: “Comment” functions on web sites and most blogs, like WordPress, TypePad, Blogsmith, MovableType &c. Normally the comment relates to the whole post only, but there is also an exception: the Digress.it plugin for WordPress, which lets you comment on single paragraphs.
End User Perspective: Very convenient to leave a comment or start a discussion. On longer threads, the missing export function becomes a nuisance: I’ve seen more serious threads copied into personal blogs by their authors just to preserve them.
2. General Web Annotations
But the same museum’s website has also some interesting stuff Brunelleschi has never seen before: artefacts which show stylistic and technical properties which can only be ascribed to foreign artisans, most probably coming from the Orient.
Obviously, the museum staff does not recognize the importance of these artefacts and even describe them as early modern provincial works.
No need to tell them, though! Brunelleschi opens his electronic notebook – he paid for it by credit card, but that was worth it – and starts to take notes.
Most of the time he »clips« the relevant webpage – that is, he grabs the text and the relevant images only without the usual garbage on the header and footer of the page – and into his electronic notebook and then adds, on a new line, his personal remarks.
This is quite fast and very handy, and much better than mere bookmarking because when he looks up his notes – or makes a search – he quickly finds all the texts he has clipped inside his notebook.
He knows exactly about the importance of his electronic notebook, and therefore he’s happy he’s found a commercial provider with a good reputation – not one who might be gone tomorrow – and with the possibility to export and archive all his notes.
Brunelleschi’s notebook is even securely protected with a seemingly good encryption, to make sure nobody of his colleagues can snoop in. There is only one exception: to a certian young researcher who’s dealing with oriental artists he’s given acces to all the notes relating to oriental stuff: it’s enough to »tag« (another one of these catch words! his notes with a relevant tag like »Oriental« and both of them have access to the same notes. By sharing their notes both are profiting from the other’s expertise.
Overview: Note taking allows for rapidly collecting ideas from different web sites and store them into an electronic notebook. Depending on the software you can also copy text fragments from the web page into you notes or »clip« the whole story.
Target: All web sites
Functions: Some note taking apps allow sharing notes (via URL), and sometimes even following, where you automatically see the other’s notes. Tagging is mostly available, but I haven’t yet heard of a reply function.
Requirements: On the user side, a subscription to one of the note taking services is necessary. The service can then be used for all websites. Web site owners instead need not do anything.
Storage: Notes are stored at the service provider, who might give you the possibility to export them into compatible formats (mostly XML).
Reuse: Reuse of the collected material is one of the main selling points of these systems, so tools are provided on-site or even as separate applications for your desktop.
Available services: Elektronische Notizblöcke wie Evernote, Simple Note, Springpad etc.
End user perspective: Very much common among junior researchers for its ease of use and ubiquitous availability, including mobile devices. Highly regarded for collecting and ordering (using »tags«) research material.
3. Site-Specific Annotations
The real day-time work of Brunelleschi though is the administration of a study group for his research institute, which has grown to 5 full time and 2 part time workers. It takes a lot of time and energy to guide his people … and to avoid they chase phantoms!
Fortunately, Brunelleschi has taken care to install a commenting system which allows him to look at all the writings his workers are preparing and to leave a note: most of the time it’s a simple advice, a positive note, sometimes he takes care to have a longer discussion.
It’s also kind of an incubator, because all discussions – his notes and his worker’s replies – are behind a firewall and cannot be seen from outside. But for the study group, these notes and replies which always bear the author’s name and a time stamp, are permanently visible and, in fact, end up being part of the project.
At the end of the project, all texts – and all the notes – will be permanently archived in the institute’s long term archival system, where future researchers will find them.
Overview: A side-wide annotation systems allow to annotate large texts, or group of texts, within a controlled environment. Its users are mostly employees who automatically have access to the system. The system might mostly be used for revisioning documents (e.g. manuals).
Target: Unfortunately, the system works only on specially prepared websites.
Functions: Sharing annotations is automatically part of the process as a whole group of people will be assigned to the task. But you will be able to share annotations only withing the work group. Replying, and maybe even tagging will certainly be possible, but a “following” function is rare.
Requirements: On the user side, a subscription to service is necessary – if not automatically provided company-wide. On the provider side, these systems are mostly deployed by larger corporations, research institutions, and organizations like Europeana which can justify the complex and costly installations.
Storage: Comments are stored at the company or institute only, which might – or might not – give you the possibility to export them.
Reuse: Most systems are closed in the sense that they don’t allow for (or foresee) output and reuse outside the system itself.
Available services: The only working(!) system I know of is Highlighter (link) which is a commercial service mostly used in educational context.
End user perspective: The end user will see the system mostly as employee of a company or institute – adding notes to the document pool will be part of his normal work, but the result will mostly not be his own “intellectual property”.
4. General Web Annotations
For his personal studies about Dante’s »Divina Commedia« and its influence on early Renaissance artists our professor Brunelleschi is using yet another instrument, which allows him line-for-line commenting on texts, but is adapt at being used on all web pages, not only texts which reside on his institute’s server.
In this case it is necessary to annotate texts residing foreign servers, mostly in the US but also in Italy and some texts in Germany, and to add annotations without these servers even knowing about it.
At the same time, Brunelleschi can virtually work together with his colleague in L’Aquila, Italy, because the both see the same texts and there is a mechanism to reply to the other’s annotations. On a normal day, the time it takes his colleague in Italy to respond to one of his annotations is only a couple of minutes!
Brunelleschi can display the texts, the layered annotations and even a special page where all text fragments and annotations are collected, which serves him well when he has to write down an article.
Overview: Annotating texts line-for-line is a very demanding task for any application especially if it’s supposed to work on any website. Although extremely useful for intensive scientific research, until spring 2012 there was no working(!) application available for the common user.
Target: All web sites
Functions: Sharing annotations, following other users, tagging and replying are available.
Requirements: On the user side, a subscription to (the only) one of the commercial annotating services is necessary. The service can then be used for all websites. Web site owners instead need not do anything.
Storage: Annotations are stored at the commercial service provider, who gives you the possibility to export them into compatible formats (mostly XML).
Reuse: Reuse is at the forefront of all services, with possibilities to re-arrange material, and re-tag it, up to export functionality as MSWord.
Available services: As of now, I only know of Annotary link. A kind of similar service is Scrible which copies (clips) a website and then lets you annotate it (the clipped website, not the original one!).
End user perspective: Great for scientific work. Very young service provider, so no long time experience available. Export functions – as of now – are only print/pdf, but more (MSWord) is promised.
5. General Web / Public Commenting
At the end of the day, and before leaving for home, Brunelleschi finds some time to dedicate to his hobby: in fact, few know that he is a dedicated fan of a special kind of small hand-built boats named »gozzi« which are typical of the Amalfi and Sorrento peninsula. In the last days thee was some talk about a new boat by famous builder Aprea, and Brunelleschi immerges himself into the discussion.
Finally he finds the first images of the new boat – an open 7.50m boat – and puts a comment on the web page. At the same time, he shares the comment with his friends by using »Circles« function, which allows him to fine-tune who exactly will see his post: only his close friends, only the Aprea aficionados or the general public. His choices depend on the subject matter, but for today he shares his comment with everyone. Soon he sees the first responses, and some further links to other images.
The comment and response system is quite rudimentary, nothing scientific here, it’s more like a marketplace where everyone shares his comments, replies to the others’ comments and then moves on. The exact membership of each circle is hard to know, because people come and go, or might only be silent onlookers.
Scope: Public commenting systems are mostly used for rapidly sharing news to a larger, sometimes undefined audience. The content of the comment is mostly not much more than a simple “Hey, look here!” but it’s ease of use makes up for its shortcomings.
Target: Specially prepared websites
Functions: Sharing, following, tagging and replying are all implemented.
Requirements: On the user side, a subscription to one of the social services is necessary. The service can then be used for all participating websites. Web site owners instead mostly need to install only a small script on their site.
Storage: Comments are stored at the social service provider, who rarely (as of now, I only know of Google’s Takeout service) might give you the possibility to export them.
Reuse: Only few services allow export of social comments, and thus a possible reuse – although such a reuse would be quite meaningless without the accompanying platform (and the other users’ comments).
Available services: Social comment systems like Google+, FB Comments &c.
End user perspective: Useful for quickly and easily spreading news.
Add: RE-USE (e.g. Word.Doc export for own work, etc.)
Add: Annotator & Yuma
