Reading (and writing) Opera .adr bookmarks - opera

Is there any library to parse the .adr file format used by Opera bookmarks?
Does it also support writing in that format?
At first, I'd ask for a Python library, but I'm also curious if there are such library for other languages.

There is parser example for Perl language https://github.com/cosimo/Bookmarks-Parser/

I have been tinkering with this recently and wrote parser in PHP for it.
I am not sure writing or modifying it is viable, given items contain some kinds of internal IDs whichi probably tie into Opera Link and stuff.

Parsing / Converting legacy Word documents? (msword2 / 5)

We got some really old .doc documents. Normally we use tika (our application normally does a text extract and then a PDF/A convert) but apparently msword2 (and msword5) are not supported currently. The only alternative I found was Libreoffice commandline. Is there anything else?
Searching for this is quite hard since everyone else seems to be looking for "old" as in 1995< and not <1991
We have looked into the issue a bit more and it seems that the only answer is that we need to use some version of the libwps library (which is the same LibreOffice uses).
We will look into the pros and cons of using Libreoffice commandline or the library itself and will probably just create a microservice for our application to use.

objective-c tags file for vim

I'd like to use Vim for editing sources and Xcode for all other purposes like managing, debugging etc. I've installed cocoa.vim plugin and it helps with highlighting, but I still need a way to navigate around the code. In java project I used ctags for the purpose, but it doesn't support obj-c.
So the question is: what is the easiest way to generate vi-compatible tags file for Objective-C sources?
I'm the author of the second link that jelera pointed to and must say it is now out of date.
I would follow the advice in the accepted answer of Alternatives to Ctags/Cscope with Objective-c? in order to get full Obj-C parser support in ctags.
If you use tagbar, this post will help get the new ctags binary working with it:

This is pretty much the setup I now use.

Parsing Apple.Mail's *.elmx files [MIME messages]

I'm in search of a framework, which allows to parse *.elmx email files of Apple.Mail.
Ultimately, I'd like to extract attachments from emails.
Unfortunately, I'm not aware of such a framework. Are you?
PS: For general parsing problems, ParseKit looks promising.
There is an open-source solution written almost entirely in objective-c called Pantomime although probably dated. Here's the link.
Consider using AppleScript and Automator and integrate the AppleScript in your Cocoa app.

How does wikipedia generates PDF

I would like to know on how wikipedia (http://en.wikipedia.org/) creates PDF? It seem to be using some application at the back-end. Could anyone please let me know on how this is done?
Thanks

Wikipedia runs Mediawiki.
A Google check tells me that they have two PDF extensions.
This one is the one who's still mantained: PDF_Writer
It doesn't use a PHP HTML→PDF generator, (though there are some)
It actually does something trickier and more clever.
The PDF Writer uses the Python Reportlab libraries to generate PDF based on a
DOM derived from parsing mediawiki-markup using the mwlib parser.
To confirm ZJR's answer, these are the document properties:

A technology for reading pdfs online with annotations?

is there an open source solution that displays PDFs for online reading? It has to be searchable much like google books and if possible has the ability to display annotations?
By "online reading" I'll assume you mean without a PDF reader plugin on the client. In that case you'll need to convert to HTML
http://pdftohtml.sourceforge.net/
If you don't mind losing the ability to copy text then converting to PNG may give you a more accurate rendering
http://www.imagemagick.org/
Regardless of the output format you can manage your searching using the original PDF data. One technology for this is mnogosearch
http://www.mnogosearch.org/
Monogosearch uses pdftotext internally, you may find this useful if you want to write your own search routines. pdftotext is part of the Xpdf suite of utilities
http://www.foolabs.com/xpdf/about.html
All of the tools listed above are available on Windows or Linux
You may also be interested in the Vuzit DocuPub Platform: http://vuzit.com/products/docupub_platform
The display technology itself is not open source, but they provide an API to access their service, so perhaps it is worth investigating.
Don't know if you are looking a software to install or some service to pay for...
I've read a lot about www.getbackboard.com (this is not advertising, only reporting something I've read about, that maybe fits your needs.. ;)
Not sure if they do annotations, but both of these will show PDFs quite well:
http://pdfmenot.com
http://docs.google.com
ICEPdf recently released their code as open source. It is Java based.
PyPdf is really nice. It supports reading the text as well as encryption which I know that itextsharp does not.
Of course you'd have to program in python as IronPython's class libraries aren't quite to the point where you can ref them from another language and use them. (But I imagine they will be someday soon)
PyPdf
This is not open source, but check it out anyways. You can download a free trial of their SDK to try it out. Reading PDF's and their annotations is not simple and I wouldn't trust a production app to open source decoders.
Here is an online demo.

Another good pdf reader is FoxitReader.
