There are many types of identifiers, and it depends on your data which is more useful. Identifiers can be anything: a name, an official name, a tax number, a country code, an industry code, etc. An example of country or region codes is the NUTS classification. Examples of industry codes are: NACE, SIC & NAICS.
This section focuses on company identifiers. These identifiers can be used to search or download data for specific companies. Afterwards they can be used to combine datasets. Many databases with financial data include several of these identifiers. Some of these identification codes are proprietary and are therefore only available in databases owned by specific data suppliers.
Some commonly encountered company codes are:
There are many more codes or names but the above mentioned codes are the most commonly encountered and used codes in licensed financial databases at VU Amsterdam. An overview of most often encountered identification codes with some important databases that have them is available here. You can also use this overview to select an identifier that you can use to combine multiple databases.
An identifier is a number of characters and may look like a regular number. When you work with datasets you need to be careful that the software reads or imports identifiers as strings or characters but not as numbers. This is not only important when combining data but sometimes also when downloading data in a format like Microsoft Excel, or when viewing or opening a dataset.
Excel or other software sometimes formats codes as if they were numbers. Example: the code "0068G78" would be changed to "68G78". For a number, the leading zeroes have no value, but for an identification code they can be very important. Code "0068G78" proably refers to a different firm than "68G78". In Excel, such original codes can usually be repaired using the REPT() function :=REPT("0";X-LEN(Cell))&Cell
Explanation: This function will repeat/add the character Zero ("0") to the characters in a cel, and the number of zeroes depends on the X minus the Length (= len() ) of the number of characters already in the cell. The value in the original cell will be added to this.
NARCIS is dé nationale portal voor wie informatie zoekt over wetenschappers en hun werk. Naast wetenschappers maken ook studenten, journalisten en medewerkers binnen onderwijs, overheid en het bedrijfsleven gebruik van NARCIS.
NARCIS biedt toegang tot wetenschappelijke informatie waaronder (open access) publicaties afkomstig uit de repositories van alle Nederlandse universiteiten, KNAW, NWO en diverse wetenschappelijke instellingen, datasets van een aantal data-archieven, alsmede beschrijvingen van onderzoeksprojecten, onderzoekers en onderzoeksinstituten.
Dit houdt in dat NARCIS (nog) niet gebruikt kan worden als ingang tot complete overzichten van publicaties van onderzoekers. Er zijn echter steeds meer instellingen die al hun wetenschappelijke publicaties via NARCIS toegankelijk maken. Op deze wijze kunnen de publicatielijsten van de wetenschappers zo compleet mogelijk worden gemaakt.
In 2004 is de ontwikkeling van NARCIS gestart als een samenwerkingsproject van KNAW Onderzoek Informatie, NWO, VSNU en METIS in het kader van de dienstenontwikkeling binnen het DARE-programma van SURFfoundation. Dit project heeft de portal NARCIS verwezenlijkt, waarin in januari 2007 de dienst DAREnet is geïncorporeerd. Sinds 2011 is NARCIS een dienst van DANS.
A MOOC is an online course aimed at unlimited participation and open access via the web.
National Academic Research and Collaborations Information System
NARCIS is the main national portal for those looking for information about researchers and their work. Besides researchers, NARCIS is also used by students, journalists and people working in educational and government institutions as well as the business sector.
NARCIS provides access to scientific information, including (open access) publications from the repositories of all the Dutch universities, KNAW, NWO and a number of research institutes, datasets from some data archives as well as descriptions of research projects, researchers and research institutes.
This means that NARCIS cannot be used as an entry point to access complete overviews of publications of researchers (yet). However, there are more institutions that make all their scientific publications accessible via NARCIS. By doing so, it will become possible to create much more complete publication lists of researchers.
In 2004, the development of NARCIS started as a cooperation project of KNAW Research Information, NWO, VSNU and METIS, as part of the development of services within the DARE programme of SURFfoundation. This project resulted in the NARCIS portal, in which the DAREnet service was incorporated in January 2007. NARCIS has been part of DANS since 2011.
When people create educational resources, they may choose to share them with others openly and freely. This means that others can use these materials as part of their courses and lessons without permission. A creator of an open textbook, for example, can give explicit permission to others to use their book free of charge. We call these open education resources (OER).
