Definition Title of the dataset Specifications e Required field e May be used only once e 1 to 160 characters permitted from the entire printable ASCII character set e All 160 characters must be entered on one line Use e Title should be descriptive enough so that when a user is presented with a long list of titles the user can determine the general content of the dataset e In order to make titles descriptive important elements about the data may be included in the title i e parameters measured geographic location instrument investigator project temporal coverage e For readability capitalization of the title should follow standard constructs Do not use all capital letters or all lower case letters but use the appropriate case where applicable Example Hourly Tidal Observations from the Coast of China 1942 1986 5 1 2 Summary The Summary Assistant can be used as a guide to assist in completing this field e Required field e May be used only once e Multiple lines of text are allowed each line containing a maximum of 80 characters Characters may be selected from the printable ASCII character set e Should include information needed for a user to determine the usefulness of the dataset e Should start with a topic sentence describing what information is in the dataset Often this is some measurable quantity or quantities such as sea surface temperature human popula2. undocumented data may lose their value New employees may have little understanding of the contents and uses of a digital database and may find they don t understand the results generated from these data Lack of knowledge about other organisations data can lead to duplication of effort It may seem burdensome to add the cost of generating metadata to the cost of data collection but in the long run it is worth it The information needed to create metadata is often readily available when the data are collected A small amount of time invested at the beginning of a project may save money in the future Data producers and users cannot afford to be without documented data The initial expense of documenting data clearly outweighs the potential costs of duplicated or redundant data generation 2 2 DATA DIRECTORY OVERVIEW A fundamental component of the management of marine data is to know what data exists both within an organisation and from other organisations The ability to quickly locate a dataset and determine its relevance is of prime importance This is the purpose of a data directory A data directory contains metadata or data about data Metadata includes a description of each dataset the physical location of the dataset the geographic area covered and the person responsible for the dataset content A data directory provides an efficient management and search tool to allow organisations to describe their data holdings as well as informing t

13. EDI BACKGROUND AND OBJECTIVES The Marine Environmental Data Information Referral Catalogue MEDI is a directory system for datasets data catalogues and data inventories within the framework of the IOC s International Oceanographic Data and Information Exchange IODE programme It has been set up to ensure the widest possible coverage of data holdings and included a review of existing national and international data directory systems as well as implications of inter operability with similar systems within other international organisations The development of global data directories in particular the Global Change Master Directory resulted in a review of the MEDI structure to ensure its compatibility with other directories The ability to merge metadata collected by MEDI with global data directories was considered to be an essential component of MEDI This version is compatible with the GCMD DIF structure The objectives of MEDI are to develop a global database of information on data holdings held in the IOC Member States and agencies with the following specifications e the database will be a compilation of input assembled by IOC Member States and relevant agencies e acentral database will allow end user to search as a minimum on location data type temporal resolution and organizational parameters e a central database will provide the end user with information describing the selected data holdings and their sources e the system w

Other pertinent information Example This Seasat dataset contains Level 1b altimeter data The parameters are the satellite height above the sea surface from the altimeter sigma naught and the satellite height with respect to the reference ellipsoid from orbit determination The dataset volume is approximately 3 5 GB and the smallest order is approximately 140 MB SEASAT was launched on June 28 1978 carrying a five sensor payload and operated successfully until a power failure brought transmission to a stop on October 10 1978 Its height and inclination were 791 km and 108 0 deg respectively The objective of the altimeter ALT was to determine ocean topography with a height measurement precision of 10 cm Altitude was determined by measuring the time required for a pulse to be transmitted reflected from the ocean surface and received by the altimeter The ALT carrier frequency was 13 5 GHz and operated in chirp pulse mode with a 3 2 micro sec uncompressed pulse width and 3 125 nano sec compressed pulse width The pulse limited footprint diameter was 1 2 km for calm seas and 12 km for rough seas 5 1 3 Parameters Definition Describes the types of measurements represented by the data Specifications Required field e May be repeated as often as necessary e Parameters include Categories Topics Terms Variables and Detailed Variables Example MEDI User Manual page 11 Within the group Cate
