Noosphere Tables

Noosphere Tables

1 acl_default_uid_seq

• val [int(11) NOT NULL AUTO_INCREMENT]: acl_default unique ID counter sequence.

2 acl_default

This table stores each user’s default ACL rules. These rules are applied to that user’s objects when new objects are created. This table is virtually the same as the ACL table, which makes sense: you can think of its function as having some of its rows copied to the ACL table upon object creation events.

• uid [int(11) NOT NULL AUTO_INCREMENT]: unique ID of row

• userid [int(11) NOT NULL default '0']: user who owns this ACL entry.

• _write [tinyint(4) NOT NULL default '0']: write flag.

• _read [tinyint(4) NOT NULL default '1']: read flag.

• _acl [tinyint(4) NOT NULL default '0']: can change ACL flag.

• subjectid [int(11) NOT NULL default '0']: subject (user or group) ID this entry pertains to.

• user_or_group [char(1) NOT NULL default 'u']: is the above ID a user or group.

• default_or_normal [char(1) NOT NULL default 'n'] is this a normal (specific) rule or a default rule for when no specific rule is found?

3 acl_uid_seq

• val [int(11) NOT NULL auto_increment] counter for unique IDs in acl table.

4 acl

This table stores access control rules. Every Noosphere object has associated to it one or more entries in this table which describe who has what permissions to read the object, write to it, or control access to it (change ACLs).

• uid [int(11) NOT NULL default '0']: Unique ID of this rule.

• user_or_group [char(1) default 'u']: Does this rule pertain to access by a user (u) or a group (g)?

• _write [int(11) default '0']: Flag describing write access.

• _read [int(11) default '1']: Flag describing read access.

• objectid [int(11) NOT NULL default '0']: Identifier of object to which access rule applies.

• subjectid [int(11) NOT NULL default '0']: Identifier of user or group who is being granted access.

• _acl [int(11) default '0']: Flag describing permission to control access.

• tbl [varchar(16) NOT NULL default '']: Table in which the object to which the rule applies resides (also can be thought of as object type).

• default_or_normal [char(1) default 'n']: Is this a default rule or a normal rule? Default rules apply when no specific rule is found (group ID or user ID of the accessing user does not match anything).

5 actions_uid_seq

• val [int(11) NOT NULL auto_increment]: unique ID counter for ’actions’ table.

6 actions

This table exists to keep track of user actions such as voting in polls. Each action gets a separate entry in the table so as to make it possible to do things like ensure that no one votes twice.

• created [timestamp(14) NOT NULL]: Date of action.

• uid [int(11) NOT NULL default '0']: Unique numerical identifier of action.

• userid [int(11) default NULL]: Identifier of the user performing the action.

• objectid [int(11) default NULL]: Identifier of the object on which the action was performed if applicable.

7 authors

This table documents the authors of an object (anyone who has written to an object will be in here). There is a separate entry for each combination of author and object.

• tbl [varchar(16) NOT NULL default '']: Table in which the object authored is to be found.

9 blacklist

The blacklist is a list of perl regular expression masks which are checked against the email address of each new user. When there is a match, the user’s application is rejected. This can be used to prevent attacks where one person creates many accounts, each with an email address that fits a regular pattern.

• textbfuid [int(11) NOT NULL default '0']: Numerical identifier for record.

• textbfmask [varchar(128) NOT NULL default '']: Regular expression describing some addresses to be blocked.

10 books_uid_seq

• title [varchar(255) NOT NULL default '']: Title of book.

12 cache

The cache table is the structure necessary to maintain an accurate cache. It works like this: The table starts off empty. A user requests an object from browsing PlanetMath. The request is served by a perl function which checks the cache table for the ’name’. If the name is not present, it then calls a procedure which generates the page to the cache directory and proper sub directories (based on the namespace id string). In the meantime, the entry in the database is still ”0” for invalid, but ”1” for build. this means all subsequent requests will end up waiting and rechecking the database every (some interval) for valid to go to ”1”, at which point the page will be served from the cache location. when the page is doing being built, build goes to 0 and valid goes to 1.

The ’rrequests’ column tallies the outstanding render requests, and re-renders are prioritized to the objects with the most requests.

Note: If the object is not in the table, this is essentially equivalent to a value of ”0” for valid, except after the object goes valid, It should always have an entry in the table. This will not hold if the entire cache table is cleared—which is never normally done, but should be safe and can be used to “reset” the system if necessary.

• build [int(11) default '0']: 1 if object is being built, 0 if not.

• objectid [int(11) NOT NULL default '0']: Identifier of objects stored in cache.

• tbl [varchar(16) default NULL]: Table in which object being cached resides (can be thought of as object type).

• valid [int(11) default '0']: 1 if valid in cache, 0 if not

• bad [int default 0]: The object can be marked “bad” if it will not render; in which case the system will ignore it and output a special message when an attempt to display it is made. As of now, this flag can only be set through the database, as there is no front-end provision for it.

• rrequests [int(11) default '0']: Number of re-render requests outstanding; used to prioritize rendering.

• method [char(3) default NULL]: Rendering “method”—“l2h”, “png”, “src” for now—potentially other in the future (such as MathML, which could be encoded as “mml”).

• touched [datetime default NULL]: When the the cache entry was last modified; used to determine which entries have “timed out” rendering.

13 catlinks

This table stores intra-category scheme links. These are interpreted as directed links, going from a to b (or left-hand to right-hand).

28 inv_dfs

Invalidation table – document frequencies.

The invalidation system maps word tuples to entries so that the system can invalidate (in terms of rendering cache) entries that may be effected by the addition or removal of terms to the corpus.

This table primarily keeps track of document frequencies – the number of documents (objects) a word or phrase appears in. This is used for determining whether even longer phrases (generated by adding one word to the current phrase) need to also be indexed. This is key in making this into an adaptive inverted index tracking tuples, not just single worlds.

• id [int(11) NOT NULL]: The word or phrase ID.

29 inv_idx

Main invalidation index of occurrences.

Note that unlike a search engine index, we do not bother tracking term frequency (the actual count of occurrences in the document). This is because we only care about whether the phrase occurs at all in the record (if so; we may need to invalidate the object; if not, then we can ignore it).

• id [int(11) NOT NULL]: Word or phrase ID.

• word_or_phrase [tinyint(4) NOT NULL]: Whether the current record is for a word or phrase (tells us what table to look it up in).

58 relsuggest

This table exists to keep track of suggestions regarding reciprocal “related” links (the contents of “see also” fields when an object is viewed). When a related link is created, the owner of the destination object needs to receive a notice asking whether the reciprocal link should be created. When this happens, an entry is added to this table, so that the owner of that object is not asked again whenever the related list of that object is edited.

• related [varchar(255) NOT NULL default '']: Canonical name of the related object under consideration.

• objectid [int(11) NOT NULL default '0']: Object ID of the outgoing related link in question.

• tbl [varchar(16) NOT NULL default '']: Table ID of the above object.
