Statistical metadata and data quality

Metadata

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

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.

(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.

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 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.

Beginning from 2002 every person has a travel document, and the personal data of a child is no longer entered into the document of a parent.

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)).

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

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 database now holds details of 7.1 million stolen and lost travel documents, including 550,000 blank documents.

The UNOSAT service works closely with the Department of Peacekeeping Operations and other United Nations entities to populate that database on metadata.

I have since confirmed the existence of a draft business continuity and disaster recovery plan. My team has also provided the OCG with comments on a draft ICT policy document.

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.

The key is accurate content both indicators and supporting metadata.

OECD reported on its positive experiences in implementing a Quality Framework that included reviews of its services by peers, producers and users, and stressed the importance of metadata within this Framework.

Using meta data to index pages was found to be less than reliable, however, because the webmaster's choice of keywords in the meta tag could potentially be an inaccurate representation of the site's actual content.

We recommend strong support for continuation of the initiative of the Inter agency and Expert Group, led by the Statistics Division, to improve the availability and quality of metadata supporting the MDG database (see para.

The Statistics Division is studying the possibility of implementing applications similar to MetaStore as a management tool for its metadata.

(a) Define the modalities of a report on the ability of countries to produce individual indicators, not imputations by international agencies, and on how metadata should be presented to accompany indicators on all Millennium Development Goals
