Managing digital content
Acquiring a basic knowledge and practice of records or collection management is a pre-requisite for properly organising and managing any volume of digital content beyond a few dozen items. Over time you can expect that your content will need to be added to, removed, or updated. A workflow process and good content organisation will be essential to protect your content from loss or corruption. This can be greatly assisted by using a repository, content management, library, or database system that supports open standards, and by adopting a few good planning practices.

Digital lifecycle management
To successfully manage the whole lifecycle of digital content, some attention needs to be paid to designing your workflow process from acquisition or creation through to storing your content for future access and retrieval. Digital content is able to be re-used without limit or wear. If you follow good practice for managing your digital content, chances are that in fifty or a hundred years items digitised or created today will still be viewable and usable. A consequence is that some content will never be 'archived' in the traditional sense of items no longer having an active use. Much of it may survive past the original creator, copyright term, and even the organisation responsible for keeping it.
It is important that your digital workflow process takes into account the nature of your content and why it is being collected or kept. Good practice across all the collecting and record-keeping professions includes the following:
having a written policy for managing digital content, covering items such as who can make decisions about accession and disposal, what can be collected, what standards and formats are used, and how the content and ownership rights (including copyright) will be dealt with if the organisation winds up
inventorising and describing the history of your digital content and any changes made through use of administrative metadata. This is important for tracking the source of an item and whether it has changed or been tampered with, something that is much harder to detect than with physical items
having someone responsible for entering information and doing so in a consistent way. Tied in with this is having an authentication or security feature that controls access and alterations to prevent accidental loss or misuse
using a hierarchical classification and file-naming system that shows relationships between groups of content and ensures that all content can be retrieved and accounted for in a consistent way identifying the steps needed to back up, archive, and migrate your content for long-term preservation.
Digital management solutions
There are basically three kinds of software systems used for managing digital content: databases, content management systems, and repositories, each with a different focus and function. You need to be clear about what your needs are before investing time and money into a new system, as some may not be suitable for your content, organisation, or budget.
Databases
Database systems are typically used to describe and track content collections, whether digital or not. They are primarily metadata systems and do not hold or store content objects beyond basic elements such as sample content (e.g. extracts, thumbnails, short audio clips) that form part of the metadata.
Catalogue and record index databases are commonly used in libraries, archives, and businesses as part of library and basic record management and tend to cover non-digital items or mixed items. These databases range from simple spreadsheets to server-based applications designed to point to and integrate with other information systems.
Inventory, library, and collection management software also tend to be database systems, but with more extensive metadata (i.e. including technical and administrative metadata as well as descriptive and discovery metadata). For the differences on these types of metadata, see our Describing Digital Content guide. These are widely used in museums and libraries where there is a need to inventorise and track collections, usage history, access restrictions, valuations, and other aspects of a collection. They are distinct from content management systems, as, like catalogues and record indexes, they do not store content objects beyond basic elements.
A database solution might suit your needs if one or more of the following applies:
your digital content is primarily metadata or a finding aid for non-digital items
your content is part of a series or combined grouping of digital and non-digital items
your content management needs are relatively simple.
Content management systems
Content management systems include photo libraries, digital asset management systems, electronic records and document management systems (ERDMS), and web-oriented content management systems. These systems store or organise content as well as enabling collection and record metadata and the ability to track content and control versions.
Photo libraries and digital asset management systems are most often used in environments that produce or publish new materials using the stored digital content. Stock or commissioned images, graphical items, audio-visual materials, branding and re-usable text items are common examples. Professional photographers, publishers, broadcasters, audiovisual studios, web or graphic designers and others who deal with creation, editing and manipulation of digital content tend to require these kinds of systems.
Electronic records and document management systems are usually found in government, business or office environments, and some publishers. They are used for managing digital document creation and storage along with digitised records in a controlled number of formats. They can vary from simple database systems containing client or customer information through to end-to-end document production and archiving systems. These systems are focused on version control and formal record creation, allowing parts of the collection to be made read-only or given restricted access while others can be freely edited. They should also allow digital archiving over time as records with no active business use get migrated to long-term digital storage.
Web content management systems are generally hosted on a local or remote web server, enabling the upload of a variety of content for use in developing website content or for making available as downloadable media from websites. Apart from administrative restrictions (such as limits to editing rights), web content management systems frequently have only minimal collection, version, or metadata control. Some metadata may be uploaded with the content, while discovery metadata may be separately added to the website content as tags and keywords. Generally these systems are not suitable for long-term content or ollection management, storage, or archiving.
A content management solution might suit your needs if one or more of the following applies:
your digital content was originally created digitally
the digital copy will or does permanently replace the original
digital content items need to be able to be changed or added to
the digital content is being primarily managed and accessed on an intranet or the internet.
Repositories
A digital repository is a software system for centralised storage of, access to, and management of digital content, generally in a networked environment. Some repositories focus primarily on storage and access, while others function as a digital equivalent of a traditional library system. These digital libraries are repositories that accept content and then classify, catalogue, preserve, curate, and enable retrieval of the content throughout its lifecycle.
Repositories are commonly used by libraries, archives, universities, research institutes, and other institutions to manage and store digital content over the long term. Many are capable of dealing with structured and unstructured content and a variety of formats. The software system may provide a different form of access to a repository depending on whether the user is submitting, curating, or retrieving content.
Repositories are suited to long-term storage and archiving of digital content and are the best means of ensuring preservation of a digital collection over the long term. However, they are also generally more complex to manage than databases and content management systems, and may require multiple software applications or modules (for instance to submit content, view content, or archive content) to achieve full functionality.
A repository solution might suit your needs if one or more of the following applies:
digital copies will be permanently accessed as a substitute for the original
you are dealing with a variety of different and unrelated formats and collections
you mainly need permanent storage for user access and archiving.
Assessing software system requirements
To ensure the longevity of your digital content, we recommend that you choose a system that at minimum:
manages the original file format of the content without alteration
supports recognised open standards and schemes for all metadata
has regular software updates and service support to maintain usability
allows transparent importing and exporting of all your content and metadata to assist migration.
Ideally your system should also be one that:
maintains your content in open containers (e.g. folders) that can be accessed by any suitable software
maintains your metadata in open formats readable by any suitable software
embeds all metadata into the original file where the file format supports it
is built using open-source software that allows different vendors or developers to provide service support over time
includes a built-in archiving or backup function to protect the content from accidental loss or destruction.
If you are maintaining public records in digital format, Archives New Zealand has issued specific standards that are required to comply with the Public Records Act, including restrictions on document disposal and destruction. Information and advice on these are available from www.archives.govt.nz/advice.
