This is the root schema, which is imported by all of the other schema. It provides the about_Type data-type that will be used for configuration management. The about_Type includes a URL that provides the address of Supplementary_Info which would be located on a separate web page. This supplementary information could include some of the authors and a change list. Since about_Type when extended in other schemas to include fixed values was not valid under XML schema 1.0, an XML page has been generated from the about_Type and has been included in an appinfo element. The first line of the XML page, ?xml version="1.0"?, had to be omitted in order to permit validation of the about schema. However, the about_Type is usable for XHTML web pages and XML files. Robert Cary Leif Ph.D. Josef Spidlen Ph.D. about:about; Some of the elements and attributes are loosely based on the Dublin Core. This schema includes the elements and attributes (metadata) that are necessary to manage the configuration of a schema. This is a DRAFT proposal that has not been formally tested to comply with the W3C XML schema version 1.0 specification. No position is taken in respect to whether a particular software implementing this schema works according to medical or other regulations.

The element,Future_Work,which is not mandatory was added to this about schema on 5 July, 2009. It will permit the addition of references to suggested extensions. Many of the data-types in this schema is derived from the Ada bounded_string type. Originaly, these strings were named Bd_Some Integer_Type, e.g Bd_16_Type. The names have been changed to Bounded_Some Integer_Type , e.g. Bounded_16_Type. This change has been made because BD, Becton Dickenson, is a major cytometry supplier Initially, the id attributes were included as a means to permit the complexTypes present in XSD schemas to be simply referenced by RDF. A solution that includes the use of an id attribute has been suggested in the document below to permit the use of derived simpleTypes. This and the other schemas will follow this suggestion and extend it to complexTypes. This turns out to not be necessary because the simpleTypes of the elements within a complexType have always been visible in the CytometryML schemas; and therefore can be referenced by RDF. The length of the reference to the elements based on the complexTypes may have been superseded by the use of CURIES. XML Schema Datatypes in RDF and OWL, W3C Working Group Note 14 March 2006 This version: http://www.w3.org/TR/2006/NOTE-swbp-xsch-datatypes-20060314/ Latest version: http://www.w3.org/TR/swbp-xsch-datatypes/ The Email_Address_Type including the pattern is from PerfectXML http://www.perfectxml.com/Answers.asp?ID=3. / characters had to be inserted before dashes '-' to escape them. This is for long textual narratives or descriptions This is a string that will be created by the manufacturer or others to verify that the schema is identical to the one sent out or downloaded. The algorithm employed by the manufacturer or similar party can be secret. An example would be a cyclic redundancy check, CRC, value. Since about is the top level schema, it cannot import any of the other schemas including DICOM and Person_Name. Therefore a Person_Name_Type that does not reference DICOM had to specially be created for about. For all other uses, the Person_Name_Type in the Person_Name schema should be used. This is an extension of the DICOM responsible organization. This is an extension of Person_Name_Type This type includes humans and organizations This is an extension of Person_Name_Type The complex type about_Type should be usable for XML and XHTML web pages. The use of attributes, where reasonable, will result in simpler text for the web pages. The Maintainer_Type must be part of the about_Type, since the user should be provided with a contact, who can provide help.
