7	resourceMaintenance	0..*	Information about the frequency, scope, and responsible party for the updating of the resource.	resourceMaintenance: (MD_MaintenanceInformation) maintenanceAndUpdateFrequency: (MD_MaintenanceFrequencyCode) irregular maintenanceNote: Additions as new data are received.
8	graphicOverview	0..*	A small image that exemplifies the collective resource. The graphic file should be less than 500KB and 1000x1000 pixels. Provide URL to an image that can be rendered in browsers.	graphicOverview: (MD_BrowseGraphic) fileName: http://ngdc.noaa.gov/mgg/image/geology_mercator2048.png fileDescription: data locations fileType: PNG
9	resourceFormat	0..*	Information about the formats of the resource. This is independant of the distribution details and is useful to provide when the resource has a status of 'planned' or 'underDevelopment'.
10	descriptiveKeywords	0..*	Commonly used words or phrases which describe the dataset. Optionally, the keyword type and a citation for the authoritative or registered resource of the keywords are also provided.
11	resourceSpecificUsage	0..*	Basic information about specific application(s) for which the resource(s) has been or is being used by different users.

13	associatedResource	0..*	The citations and identifiers of associated resources, such as projects and documents.
14	spatialRepresentationType	0..*	Object(s) used to represent the geographic information.	<gmd:spatialRepresentationType> <gmd:MD_SpatialRepresentationTypeCode codeList="http://www.isotc211.org/2005/resources/Codelist/gmxCodelists.xml #MD_SpatialRepresentationTypeCode" codeListValue="vector"> vector </gmd:MD_SpatialRepresentationTypeCode> </gmd:spatialRepresentationType>
15	spatialResolution	0..*	The level of detail of the dataset expressed as equivalent scale or ground distance.	tbd
16	language	1..*	Languages of the dataset using standard ISO three-letter codes.	eng: USA
17	characterSet	0..*	Character coding standard in the dataset.	tbd
18	topicCategory	0..*	High-level thematic classifications to assist in the grouping and searching of data. Required when the hierarchyLevelName scopeCode is 'dataset'. Recommended when hierarchyLevelName scopeCode is 'series', 'fieldSession', or 'nonGeographicDataset'. The most applicable topics in NOAA are usually geoscientificInformation, climatologyMeteorologyAtmosphere, oceans or elevation. Repeat if more than one category is applicable. Keep the capitalization and spacing of the terms.	<gmd:topicCategory> <gmd:MD_TopicCategoryCode>oceans</gmd:MD_TopicCategoryCode> </gmd:topicCategory>
19	environmentDescription	0..1	Describes the dataset’s processing environment. Includes information, such as software, computer operating system, filename, and dataset size. Provide full citations in the LI_Lineage section.
20	extent	0..*	Information about the spatial, horizontal and/or vertical, and the temporal coverage of the resource.
21	supplementalInformation	0..1	Other descriptive information about the resource.	Only the portion of the SIO database funded by IDOE is in this archive.
