        Hi Hamda

        First to say that the IPTC has a document for beginners like you, this is
        the "G2 Guide for Implementers" which you can find on the Documentation web
        page of each of the G2 standards and this is the URL for the document:
        http://www.iptc.org/std/NAR/1.5/documentation/IPTC-G2-Implementation-Guide_2
        .zip


        Re your questions below:

        - an item is the wrapper for a single piece of content. For a News Item the
        content is news which can be of different media-types like text, photo,
        graphics, video etc. For a Concept Item the content is the definition of a
        concept, this could be an abstract topic like "human rights" or a real world
        entity like a specific person, a company, or a location. A special case are
        definitions and descriptions of events, which also are conveyed by a Concept
        Item. A Knowledge Item is a container for many concepts, like an
        encyclopaedia is the container for many pieces of knowledge.

        - the package item is made to wrap a set of such
        single-piece-of-content-items as described above. The primary use is to
        package news: 1 text story plus 5 photos and 1 infographic all about a
        specific topic. These 7 pieces of content exist in their own items and the
        package item acts as a list of references to these item - this way it does
        not contain any byte of content, only references to the corresponding news
        items.

        - a Catalog is part of the QCode technology of G2: QCodes identify concepts
        and have the format "scheme-alias:code". The scheme-aliases in an item must
        be mapped to URLs identifying a scheme, this mapping is provided by the
        entries of a Catalog.

        Have a good start with NewsML-G2
