At the most basic level you will use the RF to create, run and maintain test cases and user defined resources such as user keywords within your test project. At any given time, within that process, existing resources function as building blocks. That is, you will start with having only library keywords available, provided by test libraries such as the SeleniumLibrary. Utilizing these, you will then proceed to create various layers of your own, domain-specific keywords i.
But we can ignore that here because, generally, all resources should be and generally are extracted into resource files. Because of the latter test suite folders may, and often will, also contain resource files. However, in the remainder of this post, I will promote and work towards an approach in which test suite folders will never contain resource files. Of course, the artifacts that are potentially reusable, are the test libraries and the resource files.
Through importing we basically tell the RF to look for a certain resource in the generic sense at a certain location or at certain locations and, if it finds it, to integrate these resources and make them available to us, effectively extending its capabilities with these resources. Thus, when the RF encounters an import statement for a test library, it will try to find a module with the given name in any of the file system location s in which such modules are typically installed.
This is one of the reasons why we have to specify certain values for the PATH system variable after having installed Python. Similarly when running on Jython, the classpath may be of relevance to finding Java modules. When the RF finds the module and it has been properly implemented, in accordance with the RF library API , the resources contained within that module will then be made available for usage to us and our code as well as for test execution at run-time. Similarly, when importing a user defined resource, such as a user keyword library, the RF will look for the resource file in the file system location as specified in the import statement and, if it finds it and it is implemented correctly, the RF will make it available.
So, to be precise, it is the RF that is made aware of the existence of a resource instead of making an artifact aware of the existence of other artifacts. Through an import statement, the RF is extended with the capabilities of the imported artifact and it will then be possible to include the functions of that artifact into your calling structures. We now have an understanding about the types of resources that can be shared and about the mechanism that implements, enables and facilitates this sharing.
Such a mechanism, however, comes with a price. The third and final post will introduce a way to minimize these costs. This is a great article outlining the import structure of robot framework. Add to Cart.

Global Resource Sharing Written by three academic librarians, this book reviews sharing of library resources on a global scale.
With expanded discovery tools and massive digitization projects, the rich and extensive holdings of the world's libraries are more visible now than at any time in the past. Advanced communication and transmission technologies, along with improved international standards, present a means for the sharing of library resources around the globe.
Despite these significant improvements, a number of challenges remain. The authors provide librarians and library managers with a comprehensive background in and summary of the issues involved in global resource sharing.

Further, most freshwater bodies ultimately empty into the ocean and are derived through the Earth's water cycle from ocean waters. The Law of the Sea is a body of public international law governing relationships between nations in respect to navigational rights, mineral rights , and jurisdiction over coastal waters. Maritime law, also called Admiralty law , is a body of both domestic law governing maritime activities and private international law governing the relationships between private entities which operate vessels on the oceans.
It deals with matters including marine commerce, marine navigation , shipping , sailors , and the transportation of passengers and goods by sea. However, these bodies of law do little to nothing to protect deep oceans from human threats. In addition to providing significant means of transportation, a large proportion of all life on Earth exists in its ocean, which contains about times the habitable volume of terrestrial habitats.
Specific marine habitats include coral reefs , kelp forests , seagrass meadows , tidepools , muddy, sandy and rocky bottoms, and the open ocean pelagic zone, where solid objects are rare and the surface of the water is the only visible boundary.

The organisms studied range from microscopic phytoplankton and zooplankton to huge cetaceans whales 30 meters 98 feet in length. At a fundamental level, marine life helps determine the very nature of our planet. Marine life resources provide food especially food fish , medicines, and raw materials.
It is also becoming understood that the well-being of marine organisms and other organisms are linked in very fundamental ways. The human body of knowledge regarding the relationship between life in the sea and important cycles is rapidly growing, with new discoveries being made nearly every day. These cycles include those of matter such as the carbon cycle and of air such as Earth's respiration , and movement of energy through ecosystems including the ocean. Marine organisms contribute significantly to the oxygen cycle , and are involved in the regulation of the Earth's climate.
The United Nations Environment Programme UNEP has identified several areas of need in managing the global ocean: strengthen national capacities for action, especially in developing countries; improve fisheries management; reinforce cooperation in semi-enclosed and regional seas; strengthen controls over ocean disposal of hazardous and nuclear wastes; and advance the Law of the Sea.majurezoca.gq

Specific problems identified as in need of attention include rising sea levels ; contamination by hazardours chemicals including oil spills ; microbiological contamination; ocean acidification; harmful algal blooms ; and over-fishing and other overexploitation. The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet Earth. A primary concern for management of the global atmosphere is air pollution , the introduction into the atmosphere of chemicals , particulates , or biological materials that cause discomfort, disease, or death to humans, damage other living organisms such as food crops, or damage the natural environment or built environment.
Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth's ecosystems. Pollution of breathable air is a central problem in the management of the global commons. Pollutants can be in the form of solid particles, liquid droplets, or gases and may be natural or man-made. Although controversial and limited in scope by methods of enforcement, in several parts of the world the polluter pays principle , which makes the party responsible for producing pollution responsible for paying for the damage done to the natural environment , is accepted.
It is also known as extended producer responsibility EPR. EPR seeks to shift the responsibility dealing with waste from governments and thus, taxpayers and society at large to the entities producing it. In effect, it attempts to internalise the cost of waste disposal into the cost of the product, theoretically resulting in producers improving the waste profile of their products, decreasing waste and increasing possibilities for reuse and recycling. The Montreal Protocol on Substances that Deplete the Ozone Layer , or Montreal Protocol a protocol to the Vienna Convention for the Protection of the Ozone Layer , is an international treaty designed to protect the ozone layer by phasing out the production of numerous substances believed to be responsible for ozone depletion.
The treaty was opened for signature on 16 September , and entered into force on 1 January Global dimming is the gradual reduction in the amount of global direct irradiance at the Earth 's surface, which has been observed for several decades after the start of systematic measurements in the s.
Global dimming is thought to have been caused by an increase in particulates such as sulfate aerosols in the atmosphere due to human action. Global dimming also creates a cooling effect that may have partially masked the effect of greenhouse gases on global warming. Along with global warming, generalized climate change is an ongoing global commons concern. Although global warming is now a generally accepted scientific observation, the precise causes of global warming are still a matter of research and debate.
The Kyoto Protocol to the United Nations Framework Convention on Climate Change UNFCCC is an international environmental treaty that sets binding obligations on industrialised countries to reduce emissions of greenhouse gases and prevent potentially harmful anthropogenic i.

The Council operates on consensus basis, mostly dealing with environmental treaties and not addressing boundary or resource disputes. The treaty, entering into force in and currently having 50 signatory nations, sets aside Antarctica as a scientific preserve, establishes freedom of scientific investigation and bans military activity on that continent. Climate change in the Arctic region is leading to widespread ecosystem restructuring. Changes in ocean circulation appear responsible for the first exchanges of zooplankton between the North Pacific and North Atlantic regions in perhaps , years.
These changes can allow the transmission of diseases from subarctic animals to Arctic ones, and vice versa, posing an additional threat to species already stressed by habitat loss and other impacts. Where these changes lead is not yet clear, but are likely to have far-reaching impacts on Arctic marine ecosystems. Climate models tend to reinforce that temperature trends due to global warming will be much smaller in Antarctica than in the Arctic,  but ongoing research may show otherwise.
Management of outer space global commons has been contentious since the successful launch of the Sputnik satellite by the former Soviet Union on 4 October Space policy regarding a country's civilian space program , as well as its policy on both military use and commercial use of outer space, intersects with science policy , since national space programs often perform or fund research in space science , and also with defense policy , for applications such as spy satellites and anti-satellite weapons. It also encompasses government regulation of third-party activities such as commercial communications satellites and private spaceflight  as well as the creation and application of space law and space advocacy organizations that exist to support the cause of space exploration.
The Outer Space Treaty provides a basic framework for international space law. It covers the legal use of outer space by nation states. The treaty states that outer space is free for all nation states to explore and is not subject to claims of national sovereignty. It also prohibits the deployment of nuclear weapons in outer space. As of mid-year, the treaty has been ratified by states and signed by an additional 27 states. Beginning in , outer space has been the subject of multiple resolutions by the United Nations General Assembly. Of these, more than 50 have concerned the international co-operation in the peaceful uses of outer space and preventing an arms race in space.

Still, there remain no legal prohibitions against deploying conventional weapons in space and anti-satellite weapons have been successfully tested by the US, USSR and China. The Moon Treaty turned the jurisdiction of all heavenly bodies including the orbits around such bodies over to the international community. However, this treaty has not been ratified by any nation that currently practices manned spaceflight.
These claims are not internationally accepted. National budget constraints led to the merger of three space station projects into the International Space Station. The ISS is arguably the most expensive single item ever constructed,  and may be one of the most significant instances of international cooperation in modern history. It was also planned to provide transportation, maintenance, and act as a staging base for possible future missions to the Moon, Mars and asteroids.
