The document discusses the development of digital libraries from experimental stages to mature and sustainable interoperable systems. It describes three stages: 1) Experimental stage in the 1990s focusing on collections of digital materials, 2) Developing stage in the late 1990s considering custodianship and sustainability, and 3) Potential future mature stage with real interoperable digital libraries supported through normal funding channels. The goal is moving from isolated digital collections to interconnected digital libraries.

Principle 10
Environmental issues are best handled with
participation of all concerned citizens, at the relevant
level. At the national level, each individual shall have
appropriate access to information concerning the
environment that is held by public authorities,
including information on hazardous materials and
activities in their communities, and the opportunity
to participate in decision-making processes. States
shall facilitate and encourage public awareness and
participation by making information widely available.
Effective access to judicial and administrative
proceedings, including redress and remedy, shall be
provided

Exchange of Information
3. The Contracting Parties shall facilitate the exchange of
information, from all publicly available sources, relevant to
the conservation and sustainable use of biological
diversity, taking into account the special needs of
developing countries.
2. Such exchange of information shall include exchange
of results of technical, scientific and socio-economic
research, as well as information on training and
surveying programmes, specialized knowledge,
indigenous and traditional knowledge as such and in
combination with the technologies referred to in
Article 16, paragraph 1. It shall also, where feasible,
include repatriation of information.

19. A definition of the “Public Domain”
“The public domain is a range of uses of information that
any person is privileged to make absent individualized
facts that make a particular use by a particular person
unprivileged.”
Conversely:
“The enclosed domain is the range of uses of information
as to which someone has an exclusive right, and that no
other person may make absent individualized facts that
indicate permission from the holder of the right, or
otherwise privilege the specific use under the stated
facts.”

20. What is a “Commons” ???
• A commons is a limited and conditional zone of fair
use (defined both legally and technically)
• A commons permits sustainable use of a resource
without jeopardizing original ownership rights
• Supports control of patrimonial / property rights
required by owners as required by owners (for
example: indigenous peoples, national governments);
protects against unauthorized commercial use
• BUT also does permit authorized commercial uses
(i.e. is compatible with market mechanisms )
• protects organizational/individual “moral rights” (i.e.
rights of authors)
21. Digital Commons?
Digital resources as “public goods” are:
• non-rivalrous (near-zero cost for additional
increments of use)
• non-excludable (i.e.of potentially universal benefit)
• universally accessible (potentially)
(But economic inequities and newly emergent
legal/technical barriers may deny these benefits)

31. “Synthesis”? / “Integration”?
“Synthesis” :
The analytical, logical effort to complete integral information
sets by well-defined, rigorous inference.
“Integration” :
The design and implementation of technology for the digital
capture, and coherent linking of data, information and/or
knowldege
32. “a full spectrum of views on interoperability…”
• the use of common tools and interfaces that provide a
superficial uniformity for navigation and access but rely
almost entirely on human intelligence to provide any
coherence of content
• primarily syntactic interoperability (the interchange of
metadata and the use of digital object transmission
protocols and formats based on this metadata rather
than simply common navigation, query, and viewing
interfaces) as a means of providing limited coherence of
content, supplemented by human interpretation.
• deep semantic interoperability

36. The Darwin Core model (Version 1.0) suggests a
rudimentary synthetic ontological framework for
natural history information that can support and inform
searching across our full corpus of literature.
This ontology has broader applicability to most types of
digital information objects in conservation and can be
supplemented by other core elements.
