<h1>Terminology</h1>
|

|
|
|

|
|
<p>To stay sane and communicate effectively we try hard to use
|
||
|
|
consistent terminology throughout the pieces of the project. Please let us know
|
||
|
|
if things here are confusing or lacking.</p>

<dt>blob</dt>
|
||
|
|
<dd>an immutable sequence of 0 or more bytes, with no extra metadata</dd>
|
||
|
|
|
||
|
|
<dt>blobref</dt>
|
||
|
|
<dd>a reference to a blob, consisting of a cryptographic hash
|
||
|
|
function name and that hash function's digest of the blob's bytes,
|
||
|
|
in hex. Examples of valid blobrefs include:
|
||
|
|
<pre>
|
||
|
|
sha1-f1d2d2f924e986ac86fdf7b36c94bcdf32beec15

Concatenating the two together with a hyphen is the common
|
||
|
|
representation, with both parts in all lower case.

<dt>blob server</dt>
|
||
|
|
<dd>the simplest and lowest layer of the Camlistore servers. A blob server,
|
||
|
|
while potentially shared between users, is <em>logically private to a single user</em>
|
||
|
|
and holds that user's blobs (<a href="/docs/schema">whatever they may represent</a>).
