Abstract: Methods and apparatuses for accessing documents in a multi-security domain environment are described herein. The novel methods may be processor implemented methods and may include saving by a processor from a first to a second security domain a version of a document, wherein the first security is a higher security domain than the second security domain. As part of the saving operation, a determination may be made as to whether the document includes one or more components not to be accessible through the second security domain, and writing the components of the document excluding the one or more components determined not to be accessible through the second security domain into the second security domain. The methods may further include opening the document through the security domain by determining whether a version of the document has been saved to the second security domain, and if so, merging a copy of modifications made to version of the document, if there are any, into the document being open.

Abstract: Methods and apparatuses for accessing documents in a multi-security domain environment are described herein. The novel methods may be processor implemented methods and may include saving by a processor from a first to a second security domain a version of a document, e.g., a wiki webpage with multiple tear portions, wherein the first security is a higher security domain than the second security domain. As part of the saving operation, a determination may be made as to whether the document includes one or more components not to be accessible through the second security domain, and writing the components of the document excluding the one or more components determined not to be accessible through the second security domain into the second security domain.

Abstract: A file system is adapted to employ a hierarchical data structure having a plurality of linked nodes of data pointers identifying data blocks of a file to manage writing of the data blocks without knowledge of, or substantive communication with any file systems with read access. The manner of management enables another file system to coherently read the data blocks of the file, while the file system can continue with write wait free.
