Profile Name ISO 19115:2003 ECDS
Profile Version 3.0
The purpose of the metadata profile for ECDS is to identify the metadata required to accurately describe ECDS datasets. The ECDS profile is a subset of the international standard ISO 19115:2003. In addition, the ECDS profile has adopted the usage of supplementary code lists and vocabularies that assist in the description of climate and environmental resources.
In general, the ECDS profile is more strict than the ISO standard in that some entities which are optional in the ISO standard are made mandatory in the ECDS profile. Some restrictions on the number of entities permitted has also been made. Even though there are changes to the ISO standard, any metadata post that is in accordance with the ECDS profile will also be in accordance with the ISO standard.
The content of this specification might be a bit too technical for some users. However, it aims to be structured in a way that anyone with some understanding about the ISO standard and profiles can benefit from it. For a more in depth specification we refer to the official ISO standard specification.
Please read Profile Structure for a brief overview of the ECDS profile. It describes what the major parts of the profile are and how it is structured. If there are any confusions when reading the Profile Specification, please have a look at Understanding the Specification to understand it better. Types and Code Values are also included to better understand the specifics of what goes in to a metadata post.

About The Profile
The ECDS profile contains many but not all the entities defined in the ISO standard. The subset we have chosen for the ECDS profile contains entities to describe the metadata itself, the dataset, distribution and quality. The ECDS profile establishes no additional elements besides those part of the ISO standard. This chapter explains in short what parts are included in the ECDS profile. For a more technical specification, please see the chapter Metadata. Note that some of the names used in this chapter are different from the names used in the specification. This is for clarity and the differences should be obvious.
This part of the ECDS profile contains information about the metadata post itself. All values are fixed or generated when using the ECDS portal.
File Identifier - Generated identifier for the specific metadata post.
Language - Fixed to English.
Scope - Fixed to Dataset.
Date - Generated when the metadata is created.
Metadata Standard Name - Fixed to ISO 19115:2003 ECDS
Metadata Standard Version - Fixed to 3.0
Contact - Generated from the logged in user. It represents the party responsible for the metadata post. This should not to be confused with the other two types of contacts in the profile which are used for the dataset itself and the distribution of the dataset. The Contact consists of an Individual Name, an Organisation Name, an Electronic Mail Address and a Role. The Role for this specific Contact is fixed to Point Of Contact
This part of the ECDS profile contains information about the actual dataset, the distribution of the dataset and the quality of the dataset. The values are submitted by the user when creating or updating a metadata post in the ECDS portal.
A short text answering the questions what? where? and when? i.e. What has been researched? Where was the research conducted? and When was it conducted?
Indicates when major changes has been done to the dataset. It consists of a Date, and a Type which can be one of the types Creation, Revision and Publication.
It is good practice to have a version number of the dataset, if the dataset is changed now and then. This means that someone using your data knows what dataset (what version) has been used in their research. You can use your own notation of the version number; e g 1,2,3... or A,B,C...
Title is not a unique identifier. There are several organisations from which you may receive a unique identifier for your data set. This may be useful when referring to your dataset in a publication. Datasets can be moved but the unique identifier is permanent. We recommend that the Digital Object Identifier System (doi) is used.
Other Citation Details
This is the reference that is used if someone has used your dataset and it is cited in an article. References may be provided in styles used by professional scientific journals. The organisation DataCite deals with citation of datasets.
Brief description of the dataset (not the project result).
The state on the dataset. Please see Process Code for a complete list of available states.
Points of Contacts
The parties or persons to contact regarding questions about the dataset. Every Point Of Contact consists of an Individual Name, an Organisation Name, an Electronic Mail Address and a Role. The Role for the Points of Contact can be either Point Of Contact or Principle Investigator. We recommend that the user specifies at least one of each type.
Provides any graphics which illustrates the dataset. Could be a photo from the site or a graph showing a time series of the data or anything which you think illustrates the dataset. The user may submit as many illustrations as needed. The Graphic Overviews consists of a File which should be an URL to the illustration on-line, a Description of the graphic that illustrates the dataset, and the Format of the illustration. i.e. jpg, png, tiff...
At least one Keyword must be submitted, but any number will do. Keywords in the ECDS profile is selected from the GCMD Science keywords.
Limitation affecting the fitness for use of the dataset, for example “The quality of the data is not good enough to be used as input observation data in climatological models”.
We suggest you use Other Restrictions and Other constraints to specify any constraints.
Text specification of the constraints that are used. We suggest you use the Creative Commons License and write “Creative Commons Attribution". This means (in short) that this license lets others distribute, remix, tweak and build upon your work, even commercially, as long as they credit you for the original creation.
Language used in the dataset. This should not be confused with the Language of the metadata post which specifies the language in the metadata post itself.

Geographic position for the dataset represented as a bounding box (west longitude, east longitude, north latitude and south latitude).
Time period of the content of the dataset represented as a time period (begin date, end date). The time reference system is fixed to Gregorian.
If other extents are important, such as vertical extent, it can be specified here.
The person or party whom to contact regarding the distribution of the dataset. The Distributor consists of an Individual Name, an Organisation Name, an Electronic Mail Address and a Role. We suggest you use Distributor as Role.
Describes the format in which the dataset is available in. It contains a Name (e.g. xml, json, csv, grib, shape) and a Version when applicable (e.g. 2007 for Excel or 2 for grib)
References to the actual dataset. Every Resource contains an URL directly to the dataset or a portal where the dataset is accessable, and a Description about the specified Resouce. In the ECDS portal you add the dataset or portal (as an URL or uploaded file) when creating or editing your metadata post. This is why there is no Resources in the form. They are automatically attached as On-line Resources to the metadata post by the ECDS portal.
Provides overall information about the quality of the content in the dataset, such as which instruments have been used, the process by which the data are created, and the quality control of the data. The Scope of the dataset is fixed to Dataset in the ECDS portal.
Starting with Metadata every section describes an entity or value in the profile. Every section specifies a brief description and useful information about the entity or value. It also describes the context in which it reside, and any constraints of conditions if there are any. There are also a short snipplet of how the entity of value are specified in the metadata post.
All entities and values falls in one of the following categories
- Optional - if the entity or value may or may not be included
- Mandatory - if the entity or value must be included
- Conditional - if the entity or value must be included depending on some other entity or value.
Entities and values must be specified a certain number of times. The valid number of instances can be one of the following.
- 1 - means one and only one instance is allowed
- 0..N - means zero or more instances are allowed
- 1..N - means one or more instances are allowed
Entities and values all have an associated type. See Types for definitions of all available types. For entities there is a reference to the entity specification.
The root entity contains information about the metadata post itself. Besides the fixed and generated values a responsible party must be specified. Metadata must also contain Identification Info where information about the dataset is specified, Distribution Info where information about the distribution of the dataset is specified and optionally Data Quality Info where statements about the quality of the dataset is specified.

This entity contains information about parties responsible for different areas in the profile. To make the datasets and metadata posts more accessible it is a good idea to specify as much and accurate information as possible. Always try to specify an Individual Name, Organisation Name and an Electronic Mail Address if possible. This will help not only any stakeholder to communicate, but also makes it clear who is responsible for the metadata post.
... ... ... ...
Electronic Mail Address
Email address to be used in communication with the person or party. If possible, an Electronic Mail Address should always be specified.
There are only seven different types in the ECDS profile. Entity is used for grouping other entities and values together and the rest of the types are used for different kinds of values.

For example specifying a Graphic Overview
... ... ...
The most common of the types are text. Values of this type may be any text.
For example specifying John Doe as Individual Name
Values of this type must be decimal numbers to be valid.
For example specifying -12.5 as West Bound Longitude
