---

The ETSI Work Programme Advanced Search engine is designed to allow users the facility to search for ETSI work items using a large variety of search criteria. It is primarily intended for expert users, i.e. those people with a detailed knowledge of ETSI.

An ETSI document number is given once a document has entered the public domain and is made up of two parts, the document type and a string of figures.

In the TYPE drop-down menu you can select the type of document you are looking for, e.g. MI, EN, ES, EG, TR, TS.

You also have the option to leave the type blank and search for all document types.

In the NUMBER box you can type in the ETSI number if known, or a part of the number. The * symbol can be used as a wildcard to replace any unknown number or letter.

Note that the MI TYPE does not result in the production of a document so there will be no corresponding NUMBER.

In this drop-down menu you can select the technical body whose work items you are searching for. Your search will automatically include the work items of all sub-technical bodies related to the technical body you select. If you do not require sub-technical body work items then you can deselect the 'Include Working Groups' box.

If you wish to select more than one technical body then hold the Ctrl button and click on each TB of interest.

By default, only active technical bodies appear in the list. If you are interested in the work items of inactive technical bodies then click on 'Include Non-Active TBs'.

In this box you can specify a work item reference which is allocated to all ETSI work items, or a part of the reference number. The * symbol can be used as a wildcard to replace any unknown number or letter.

Most Work Item References are constructed using the following rules:

Where:

Separator: "-"

WG Code

A 2 digit code identifying the Working Group, e.g. TM 1 = 01, TM 4 = 04. If there is no WG involved, then the value 00 is used (representing the TB).

Serial number

Usually a 3 or 4 digit number allocated by the Technical Body responsible for the work item (in some cases characters or numbers with more than 3 or 4 digits are used).

In addition, a work item can be split into multiple parts with the addition of a "part" indication (-1, -2, etc.) or into sub-parts (e.g. -1-1, -1-2).

You have the ability to carry out a text search on the title of a document. The * symbol can be used as a wildcard to replace any unknown number or letter. The Boolean Search allows you to use the options 'AND', 'OR', NOT and (). For example: Benchmark AND (CS-4 OR NETWORK) AND NOT Transmission.

You have the ability to carry out a text search on the scope of a document. The * symbol can be used as a wildcard to replace any unknown number or letter. The Boolean Search allows you to use the options 'AND', 'OR', NOT and (). For example: Benchmark AND (CS-4 OR NETWORK) AND NOT Transmission.

When work items change state, their new state is flagged for a certain time (the review period). Using the "Work Item state flag" field, you can inspect all the changes made to the EWP during the current review period. You can select Work Items which have been:

• created ("new")
• substantially modified ("changed")
• completed ("finalized")
• abandoned ("stopped")
• not changed ("none")
• made historical ("historical")
• withdrawn ("withdrawn")
• transferred from one TB to another ("transferred")

during the current review period.

The review period runs from the time the Work Item state changed (eg. created, stopped) until the end of the month following that event. For example, a Work Item created in June will remain flagged as "new" until the end of July.

The settings of this field can be combined with selections in other fields, so you can choose to examine, for example, new Work Items for a given Technical Body; or stopped Work Items for which the deliverable type was EN.

Note that this search criterion cannot be used in conjunction with the "Modified During" search criterion.

IMPORTANT: When selecting the value "stopped" for the Work Item state field, remember to select "Stopped" (or "All") in the "Work Item Status" area, otherwise no Work Items will be found.

Representatives of ETSI Member organizations are encouraged to inspect the EWP on a regular basis. Further explanatory information on flagged Work Items - for example, justification for its creation, the nature of a substantive change, or the reason for stopping it - is given in a remark, which can be seen when examining the details of the Work Item (by clicking on its reference code). If you disagree with the introduction / change / abandonment of a Work Item, you should in the first instance raise the matter with the Chairman of the Technical Body concerned.

Refer to subclause 1.6.3 of the Technical Working Procedures for further details.

This drop down menu allows you to see all work items which have been modified within a period of the last 1 day, 1 week, 1 month, 1 quarter or 1 year.

Note that this search criterion cannot be used in conjunction with the "Work Item State" search criterion.

Here you are given three options;

ALL - this option will allow you to see all work items irrespective of their status.

EXCLUDE STOPPED - this option (set as the default option) will allow you to view active work items only. Note that in this context, the term active includes completed and published work items as well as those where work is still in progress.

STOPPED - this option will allow you to see only stopped work items.

FROM/TO - this allows you to view all work items which are between two particular milestones according to their progress in the standardization process. For example, all work items which are between 'Start of OAP' and 'End of OAP'. The search can be further refined by selecting a start and finish date for the query. This will only show WIs where either the achieved date or target date (planned) for the selected milestone range falls between the dates selected.

You have the option to search for all work items written by a particular rapporteur. You may type a first name, last name, a part of a name using * as a wildcard or just click on 'LIST' to get a list of all rapporteurs.

Secondly you have the option to search by the organisation of the rapporteur. You can be specific by typing for example, 'ALCATEL BELL' or if you only know that the rapporteur works for ALCATEL but you are not sure which subsidiary then type ALCATEL* and you will be given a list of all work items under the responsibility of any rapporteur working for any subsidiary of ALCATEL.

If you know that you are looking for work items attached to a particular project then select the 'Project Code' in the drop-down menu. Initially, sub-project codes are not shown to make the list more manageable. If you require a greater level of detail, you may select "Include sub Project Codes" link.

Similarly you can search for a work item by 'Keyword'.

If you wish to select more than one Project Code or Keyword, then in both cases you can do this by holding the Ctrl button and clicking on the codes required. When more than one Project Code or Keyword is selected you have the choice of combining them either with the OR function ("One Of") or the AND function ("All").

If you are aware of an EC 'DIRECTIVE' being attached to a work item you can search using this information.

It is also possible to search for 'Only Harmonised Standards' and/or 'Only Mandated Standards' by checking the relevant boxes.

You also have the possibility to view all work items attached to a particular 'STF' (Specialist Task Force).

• Users:

What is the end-use of the proposed ETSI Deliverable? Is it of interest to companies/organisations outside the telecommunications industry? Is it useful for companies or organisations seeking to improve their experience of using communications, or achieve better Quality of Service? Will it improve privacy and security of user communications?

• Consumers:

Does the topic concern communications or broadcasting in the home environment, user-friendliness of products and applications in general, accessibility, or privacy and security of individuals? Are there aspects related to individuals’ accessibility to products or services? If so, then consumer representatives need to participate.

• Environment issues:

Does the subject have any relevance or potential impact for the environment? Does the proposal have any relevance for, or potential impact on, the use of resources (energy, material, water), emissions/discharges (to air, soil, water), radiation, noise and impact on biodiversity? If so, then the work needs to involve environmental stakeholders.

• Labour:

Does the proposed ETSI Deliverable affect Occupational Health and Safety in the working environment? Are the actions of a worker operating communications equipment likely to be involved or affected, bearing worker safety in mind in particular? If so, then worker representatives should be consulted.

• SMEs:

Will the ETSI Deliverable be of particular interest for SMEs, for example will it be especially be useful for smaller companies? Will its implementation have particular implications for SMEs? If the ETSI Deliverable requires testing or third-party conformity assessment, is this likely to have high costs that would affect companies with smaller production scales? Is the ETSI Deliverable likely to be used as reference in public procurement?
Do you consider that the participation of SMEs in your TC, EP or SC should be increased? Would you like SME associations, clusters and trade bodies to be informed about it, such that they can call on their constituents to participate?

• Security and privacy:

Security is an increasingly important aspect of many ETSI Deliverables, as are data protection and the privacy of end-users, whether entities or individuals. Often these aspects are the main objective of ETSI Deliverables. But do ETSI Deliverables proposed for other purposes have implications for security and/or privacy? If so, due reference is needed on the Work Item form.

Finally, when you have entered as much criteria as you need you can choose to have the results/report sorted in one of five different ways:

• by ETSI Work Item Reference
• by ETSI Document Number
• by ETSI Document Type
• new/changed
• by Technical Body

NOTE: When the document number sort order is selected, the various versions/editions of an individual document will be shown in reverse order (i.e. newest first).

The list of work items resulting from a search can be viewed in 3 different formats (Summary reports). In each report it is possible to select an individual work item and obtain more detail.
