# Metadata and privacy
|
|
|
|
Metadata consist of information that characterizes data.
|
|
Metadata are used to provide documentation for data products.
|
|
In essence, metadata answer who, what, when, where, why, and how about
|
|
every facet of the data that are being documented.
|
|
|
|
Metadata within a file can tell a lot about you.
|
|
Cameras record data about when a picture was taken and what
|
|
camera was used. Office documents like PDF or Office automatically adds
|
|
author and company information to documents and spreadsheets.
|
|
Maybe you don't want to disclose those information on the web.
|
|
|
|
This is precisely the job of MAT2: getting rid, as much as possible, of
|
|
metadata.
|
|
|
|
# Requirements
|
|
|
|
- `python3-mutagen` for audio support
|
|
- `python3-gi-cairo` and `gir1.2-poppler-0.18` for PDF support
|
|
- `gir1.2-gdkpixbuf-2.0` for images support
|
|
- `libimage-exiftool-perl` for everything else
|
|
|
|
Please note that MAT2 requires at least Python3.5, meaning that it
|
|
doesn't run on [Debian Jessie](https://packages.debian.org/jessie/python3),
|
|
|
|
# Running the test suite
|
|
|
|
```bash
|
|
$ python3 -m unittest discover -v
|
|
```
|
|
|
|
# Supported formats
|
|
|
|
```bash
|
|
$ python3 ./mat2 -l
|
|
```
