Data Portability Kit

DPK is a Data Portability Kit. This is the Swift Army Knife that let you take back control on your online data.

Thanks to GDPR, online providers now have to offer takeout features for your data. This is a great opportunity to get back your data. It is thus now a good time to manage and possibly publish them using open tools and platform.

That said, each providers will give you access to your data in a different format.

The goal of DPK is to provide a unified tool to extract your data in a unified, ready-to-use format.

The project will create a directory structure that is directly usable with your post in Markdown format and Metadata in a consistent and unique JSON format.

With DPK, you get the change to get your data in a format that can really be reused, without any hidden dependencies.

General principles

The goal of the tool is to produce content that is self contained. As such, we do not want to rely on third-party services that can disappear at anytime. That's why as much as we can, we try to resolve short URLs to their final target.

We also do not want to promote trackers. When using Twitter oembed for example, we sanitize the provided HTML and thus we do not includes the widget.js Javascript tags. If we embed third-party content as a convenience (for playing videos inline for example), it will be asynchonously, on user demand. This, thus will be compliant with browser Do Not Track policy. We will not even check if Do Not Track is enabled and assume it is enabled (as it should be).

Data conversion

Shortlinks

URL Shorteners were popular when it was needed to share long links on Twitter, due to Tweet size limitations. Now, they are mostly used for click on shared links. Short URL also hide the real link and if the short URL service disappear or decide to redirect to another target, the original content will be lost.

That's why the toolkit provide methods to resolve short URLs and replace the short URL link with it's longer form. It helps preserving the web link feature by removing middlemen.

Twitter

You can ask Twitter to download your archive here: Your Twitter Data.
You will receive a link to download your archive when ready.

When you got it, unzip the file and convert your tweets to a Markdown directory structure with the command:

go run cmd/twitter-to-md/twitter-to-md.go ~/Downloads/twitter-2018-12-27-abcd121212 posts

It will create a directory with your data in a format you can reuse with your blogging tool platform.

In the process, it will also embed a local representation of quoted tweets and replace shortened links with their original value.

Tooling

mget

mget is a command-line tool to download web page metadata and format it as JSON.

It is able to extract metadata using various standards and specifications such as:

• HTML 5 + RDFa (Linked Data)
• Dublin Core
• Open Graph
• Twitter cards

This is an handy tool to explore the semantic web:

You can install it with go command-line tool:

$ go get -u github.com/processone/dpk/cmd/mget

Assuming you have ~/go/bin in your path, you can then run it with:

$ mget https://www.process-one.net
