‘Data about data’

Describes and locates information objects

Provides context

Enables the search-ability, browse-ability, find-ability and

management of information objects

“The invisible hand” that enables effective information

organisation

Metadata constitutes a central part of library functions

(Alemu, Stevens, Ross, & Chandler, 2012; Anderson, Delve, Pinchbeck, & Alemu, 2009; Day, 2001; Gartner,

2008; Lagoze, 2010; Nilsson, 2010; NISO, 2004; OCLC/RLG, 2001; Zeng & Qin, 2008)

As library grow, of information

increases, changes and users’ expectations

change:

Contemporary standards-based metadata approaches fail to

to adequately describe the semantic aspects of

information objects

The of documents is missing (Otlet, 1934)

“In Otlet’s world each user would leave an imprint, a trail, which would

become part of the explicit history of each document” (Wright , 2007, p.190)

Scant use of theories/theoretical frameworks in the inclusion

of socially-constructed metadata

(Coyle, 2010; Coyle & Hillmann, 2007; Lagoze, 2010; Mathes, 2004; Shirky, 2005;

Veltman, 2001; Weinberger, 2005, 2007; Wright, 2007)

(Lehmann, 2010; Andersen & Skouvig, 2006.; Floridi, 2000; Hjorland, 2000)

Developing a

Exploring the inclusion of

approaches

Inductively identify concepts

Identify principles

Develop framework

Standards-based metadata approaches imply an

philosophical perspective

Web 2.0 (socially-constructed) metadata approaches seem to

follow a philosophical perspective

Cultural artefacts very often lend themselves to various

and contexts

Theory rather than theory testing

Simultaneous data collection and analysis

Fitting for research areas

Three approaches to grounded theory method

Glaserian (Glaser & Strauss, 1967)

Straussian (Strauss & Corbin, 1998)
