HOD_GROUP

Encompasses groups of categories applicable to the Hyperspectral Open Database maintenance.

HOD_DATABASE

The CATEGORY of data items recording Hyperspectral Open Database depositions.

_hod_database.code

A seven digit code assigned by the Hyperspectral Open Database (HOD).

HOD_RELATED_ENTRY

The CATEGORY of data items used to describe the relationship between a HOD entry and related entries in the HOD or other databases.

_hod_related_entry.id

Value is a unique key to a set of HOD_RELATED_ENTRY items in a looped list.

_hod_related_entry.code

The entry identifier in the related database.

_hod_related_entry.database

The name of a database in which the related entry (with the code given in _hod_related_entry.code) is stored. If this data value is not given or has the value '.', it should be assumed that the code given in _hod_related_entry.code refers to the same database as the entry which is under discussion (i.e. from which the _hod_related_entry.code is taken).

_hod_related_entry.description

A short human-readable description of the relationship between the entries.

_hod_related_entry.uri

The uniform resource identifier (URI) of the related entry given in the _hod_related_entry.code data item.

HOD_CHANGE_LOG_ENTRY

The CATEGORY of data items used to document changes made to the Hyperspectral Open Database entry.

_hod_change_log_entry.id

Value is a unique key to a set of HOD_CHANGE_LOG_ENTRY items in a looped list.

_hod_change_log_entry.author

The name of the person that changed the entry.

_hod_change_log_entry.date

The date of the change that conforms to RFC 3339.

_hod_change_log_entry.text

A human-readable description of the change that was made.

HOD_MAINTAINER_COMMENT

The CATEGORY of data items used to store the comments of the data maintainer.

_hod_maintainer_comment.id

Value is a unique key to a set of HOD_MAINTAINER_COMMENT items in a looped list.

_hod_maintainer_comment.author

The name of the maintainer who wrote the comment.

_hod_maintainer_comment.date

The date of the comment that conforms to RFC 3339.

_hod_maintainer_comment.text

The comment text.

HOD_DATA_SOURCE

The CATEGORY of data items used to store the comments of the data maintainer.

_hod_data_source.file

Specifies file name of the file that served as a source of data in this HOD entry. The file should be recorded without the path or other URI components since these components usually have no sense on the recipient's system. In Unix parlance, the value recorded should be the basename of the original file. If the full, permanent URI is known and recorded the _hod_data_source.URI data item should be used instead. For many data sources, however, the basename contains enough information to locate the original source. For instance, CIFs published in IUCr journals have the Coeditor Code as a CIF file name permitting to identify the original paper where the structure is discussed. Other journals may use the DOI of the original article as a part of the file name of the supplementary CIF file which also permits one to trace back the original paper.

_hod_data_source.block

Specifies the name of the data block within the file specified in the _hod_data_source.file tag that served as a source of data in this HOD entry. Only the data block name following the 'data_' header keyword should be recorded, not the whole data block header; i.e. the value specified here should be 'I', *not* 'data_I', for a data block with the header 'data_I'.

Currently, only one source of data, the data block that contained cell constants and atomic coordinates, is recorded, and thus this tag is not placed into a loop. If the data source file is not a CIF, this tag is irrelevant and may be omitted or may contain value '.' (dot).

_hod_data_source.uri

Specifies the uniform resource identifier (URI) of the file that served as a source of data in this HOD entry. If the full, permanent URL is known and recorded, this may be used instead of _hod_data_source.file. For many data sources, however, the basename contains enough information to locate the original source. See the full discussion under _hod_data_source.file.

HOD_DEPOSITOR

The CATEGORY of data items used to store the information related to the depositor of the data.

_hod_depositor.requested_release_date

Defines the date after which the structure should be released into the public domain, previously being held as prepublication material and not released publicly.

HOD_DATA_FILE

Data items in the HOD_DATA_FILE category record details about the data files that the header file is associated to.

_hod_data_file.id

Value is a unique key to a set of HOD_DATA_FILE items in a looped list.

_hod_data_file.name

The name of the data file.

_hod_data_file.md5sum

MD5 checksum of the file.
