<h2>Choosing a Multiformat</h2>

<p>
<dfn class="external lint-ignore">Multiformats</dfn> enable self-describing
data; if data is known to be a Multiformat, its exact type can be determined by
reading a few compact header bytes that are expressed at the beginning of the
data. <a href="#multibase-0">Multibase</a>, <a href="#multihash">Multihash</a>,
and <a href="#Multikey">Multikey</a> are types of Multiformats that are defined
by this specification.
</p>

<p>
The Multiformats specifications exist because application developers
appropriately choose different base-encoding functions, cryptographic
hashing functions, and cryptographic key formats, among other things,
based on different use cases and their requirements. No single
base-encoding function, cryptographic hashing function, or cryptographic
key format in the world has ever satisfied all requirement sets.
Multiformats provides an alternative means by which to encode and/or
detect any base-encoding, cryptographic hash, or cryptographic key
format in self-documenting data and documents.
</p>

<p>
To increase interoperability, specification authors are urged to minimize
the number of Multiformats &mdash; optimally, choosing only one &mdash; to
be used for any particular application or ecosystem.
