This includes trade definitions, recommendations, sources, country notes, information about classifications, etc.

Statistical metadata and data quality

Metadata

Discovery metadata in order to support searches for the availability of the data. Standards such as the Dublin Core metadata initiative already exist

The development of metadata is a large and complex task.

Improvement in related metadata and data quality.

For example, IMF is evaluating whether the MetaStore computer system could fully accommodate its DQAF dissemination standards metadata model.

Quality metadata in order to enable users of the data to judge its fitness for purpose.

Metadata about meaning to understand content, concepts and definitions.

We also strongly urge that the standard of metadata should be improved.

A data dictionary, or metadata repository, as defined in the IBM Dictionary of Computing , is a centralized repository of information about data such as meaning, relationships to other data, origin, usage, and format.

(i) Metadata is the responsibility of the international agency that provides the data.

There is also need for the systems and documentation to support the metadata components.

Metadata should be prepared according to an agreed framework giving a proper description of what constitutes such data.

This ongoing exercise, including the improvement of the metadata system, will enable flexible data retrieval.

Quality frameworks include the integrity and methodological soundness of the framework of accounts and tables, dissemination standards and documentation of data sources (metadata).

The data will be transferred in Extensible Markup Language (XML) format using Statistical Data and Metadata Exchange (SDMX) cross sectional schema.

Many members of the group have had experience exploring the metadata as a result of this exercise.

This is particularly important given that a devolved model is being used for creating and storing metadata.

OECD will monitor the timeliness of data and metadata reporting.

The organizations treat metadata as an indispensable part of their respective databases and agreed to improve the efficiency of trade metadata preparation, storage, access, management and dissemination.

On the technical side, the Statistics Division developed web services for data transfers by applying Statistical Data and Metadata Exchange (SDMX) standards.

As a consequence of the continuing increase in the volume of data collected from member organizations, participants and beneficiaries, it is recommended that a central repository for data storage be created.

Feedback is important, particularly in instances where the metadata has significant deficiencies.

Useful exchanges of information took place within the Task Force on the organizations' practices with respect to data quality and metadata management.

(f) Although considerable effort went into providing metadata to support the MDG database, it fell well short of what is desirable.

OECD also presented its MetaStore, a system designed to process metadata along with their data quality framework, which should be applied to all OECD statistical domains.

The Protection Information Section was responsible for the protection related document repository, collecting information and populating databases.

The organizations agreed on a list of requirements for the data and metadata to be collected from OECD member countries.

The Task Force members expressed their interest in this metadata management system and are exploring the adaptation of this system in their environments.

It applies data warehouse technology in order to aggregate transaction information, to merge the information with CRM products, and to provide KPI (key performance indicators).

The software package for a stand alone data dictionary or data repository may interact with the software modules of the DBMS, but it is mainly used by the designers, users and administrators of a computer system for information resource management.

IMF informed the Task Force of the implementation and use of its Data Quality Assessment Framework (DQAF) as a tool for surveillance and technical assistance, and for structuring metadata for IMF dissemination standards (the General Data Dissemination System (GDDS) and the Special Data Dissemination Standard (SDDS)).

Change software repository

International organizations have begun the process of extracting data directly from countries' database systems through the Statistical Data and Metadata Exchange (SDMX).

Out of the major applications, only the CDR is still on a Windows NT platform, and work is under way to upgrade its environment and to provide additional features.

Client satisfaction surveys should be introduced to provide regular feedback on the quality of the data and metadata (see para.

The Statistics Division and OECD will ensure that users have no difficulty in accessing the metadata maintained by both organizations.

The report (E CN.3 2006 14), prepared by the United Nations Statistics Division in consultation with the Friends of the Chair, addresses the above concerns as far as available data permits, and also makes suggestions on metadata.

The largest repository is the Inter university Consortium for Political and Social Research (ICPSR) at the University of Michigan, which provides access to an extensive collection of downloadable political and social data for the United States and the world.

Install software from a high trust whitelisted repository.

Although it is pleasing to note that many international agencies are making deliberate steps to improve the metadata to support MDG indicators, some are lagging well behind.

Meta tags provide a guide to each page's content.

Specify an alternative sources.list.d file to which repositories should be added.
