Using the public folder mechanism of Dropbox, it is possible to use MolSync to make chemical data available to anyone, simply by copying a file into the public folder, or one of its subfolders. Any files within the public folder can be accessed without having to authenticate. MolSync provides ways to share this data conveniently, including a built-in feature tweet feature.
One of the features that Dropbox provides is a special folder: /Public. Any files in this folder, or one of its subfolders, can be accessed by anyone, via a particular URL. People can download any of these files without having to login or even have a Dropbox account at all, which makes it an effective mechanism for hosting files that are available for anyone to download.
The MolSync app makes use of this feature by offering a way to share chemical data particularly conveniently, via the Open in Browser menu option:
This feature composes a composite URL, which makes use of the molsync.com server to render the content as a fully marked up web page, which represents the data:
As can be seen in the banner along the top, there are a number of options for sharing this page on social networking sites:
One of these options allows the content to be tweeted, from within the browser. However, there is a more direct way to go about it.
iOS 5.0 introduced Twitter access baked into the operating system, which allows it to be configured for all apps:
Any given app must ask for permission to access your Twitter account, but once granted, permission remains active by default. This works similarly to the location services: no app is permitted to use this, unless you explicitly agree to allow it.
First of all, open the /Public folder in MolSync:
Select a chemical data file, e.g. aspirin.mol, and touch-and-hold to bring up the menu:
Select Tweet this... from the menu. If this is the first time you have used Twitter integration from within MolSync, you will be asked to grant permission to the app.
A sharing URL will be generated for the file, and a dialog will appear:
The text line contains the entire URL for the sharing page, which is quite long, so only part of it is visible on an iPhone-sized device. To add any further notes to the tweet, just start typing, and hit Accept when done. The URL will be automatically shortened when the tweet is emitted.
MolSync provides access to a variety of ways to share data. Sharing public content through a dynamic web page allows convenient access to sharing via social networking sites. Since iOS 5 was released, MolSync supports Twitter integration within the app itself, allowing public information to be disseminated with just one step.
