Mathematics encompasses a growing variety and depth of subjects over history, and comprehension requires a system to categorize and organize the many subjects into more general areas of mathematics.
 A number of different classification schemes have arisen, and though they share some similarities, there are differences due in part to the different purposes they serve.
 In addition, as mathematics continues to be developed, these classification schemes must change as well to account for newly created areas or newly discovered links between different areas.
 Classification is made more difficult by some subjects, often the most active, which straddle the boundary between different areas.

Camelot Entertainment Group, Inc. ("CMGR"), is a public company based in Irvine, California with three subsidiaries: Camelot Films, Camelot Distribution Group, including DarKnight Pictures, and Camelot Studio Group.
 Camelot is in the process of rebuilding its production and distribution subsidiaries as it continues to work on its Studio Group developments.
 As of February 1, 2017, Camelot is working toward filing a new S-1 Registration Statement in order to regain its fully reporting status and resume trading.
 The company has not traded since July 23, 2013, when it was unable to complete its annual and quarterly filing requirements due to lack of funding.
 In the interim, the company has divested itself of most of the titles it was representing for distribution as part of an overall restructuring.
 In addition to divesting the film library acquired in 2010, the company has now worked through most of the prior legal issues that arose from the acquisition of the library and is now in a position to move forward with its S-1 Registration.
 Going forward, Camelot will focus on acquiring and producing content through its Camelot Films subsidiary, direct to consumer ("DTC") digital distribution domestically as it rebuilds its foreign sales operations through its Camelot Distribution Group subsidiary, and the launch of its long planned Camelot Studio Group facility.

Protein subfamily is a level of protein classification, based on their close evolutionary relationship.
 It is typically determined by similarities in the members' 3D structures and sequences.
 It is below the larger levels of protein superfamily and protein family.
 For example, in the SCOP classification system, members of a subfamily share the same interaction interfaces and interaction partners.
 These are stricter criteria than for a family, where members have similar structures, but may be more distantly related and so have different interfaces.

The ultimate goal of meteorite classification is to group all meteorite specimens that share a common origin on a single, identifiable parent body.
 This could be a planet, asteroid, Moon, or other current Solar System object, or one that existed some time in the past (e.g. a shattered asteroid).
 However, with a few exceptions, this goal is beyond the reach of current science, mostly because there is inadequate information about the nature of most Solar System bodies (especially asteroids and comets) to achieve such a classification.
 Instead, modern meteorite classification relies on placing specimens into "groups" in which all members share certain key physical, chemical, isotopic, and mineralogical properties consistent with a common origin on a single parent body, even if that body is unidentified.
 Several meteorite groups classified this way may come from a single, heterogeneous parent body or a single group may contain members that came from a variety of very similar but distinct parent bodies.
 As such information comes to light, the classification system will most likely evolve.
The A-segment is a car classification defined by the European Commission as the first segment in the European market car classification (mini cars).
 It is a significant niche in Europe with 8% market share in 2017.
