Glossary

acl: Access Control List - you can use it to specify who may do what in your wiki.
contenttype: A formal, standardized way of specifying of which type some data is. E.g. ‘text/plain;charset=utf-8’ is the contenttype for some simple piece of text (encoded using utf-8 encoding), ‘image/png’ is the contenttype for a PNG image.
data: Just the raw data, no more, no less; can be some text, an image, a pdf.
emeraldtree: An XML / tree processing library used by moin.
flask: A micro framework used by moin.
item: A generic, revisioned object stored in your wiki storage.
jinja: A templating engine used by moin.
metadata: Additional information related to or about some data. For example, if you create a new PDF item revision, the revision data will be the PDF file’s content, but moin will also additionally store revision metadata that tells that this revision is in fact a PDF (its contenttype - we do not rely on or require .pdf extension on the item name), when it was saved, maybe some comment you gave when saving, etc.
revision: Part of an item’s history, has metadata and data created for this item at some specific time in its history. If you create an item, you create its first revision. If you edit it and save, you create its next revision.
session: As the protocol (http) used by a web browser is stateless, a means to keep state is needed. This is usually done by using a cookie stored within the user’s browser. It is used for example to stay logged-in into your user account or store the trail of items you visited and for easier navigation.
sqlalchemy: An SQL database abstraction library used by moin.
sqlite: An easy-to-use SQL database used by moin.
werkzeug: A WSGI library used by moin.
wiki engine: Software used to run a wiki site.
wiki farm: Running multiple wikis together on one server. Often, there is some shared, common configuration inherited by all wikis, so each individual wiki’s configuration becomes rather small.
wiki instance: All configuration and data related to a single wiki.
wiki item: A single content item within a wiki site.
wiki page: A single content item within a wiki site, possibly used for text-like items.
wiki site: A web site implemented using a wiki engine.
WSGI: Web Server Gateway Interface. It is a specification about how web servers, like e.g. Apache with mod_wsgi, communicate with web applications, like MoinMoin. It is a Python standard, described in detail in PEP 333.
