IFACs new building blocks approach to reporting sustainability information enhances the previously issued roadmap, The Way Forward. With this new step, IFAC hopes to foster discussion on how this approach can deliver a global system for consistent, comparable, and assurable sustainability-related information that best meets the needs of investors and other stakeholders.

When posting messaages, it is expected behavior that screen readers will default to the top-level text field of the post, and will not read the content of any interior blocks in the underlying structure of the message. Therefore, to make an accessible app, you must either:
Apps need to handle the requests that start to flow their way, and respond appropriately. Follow our guide to handling user interaction to prepare your app for the interactivity that Block Kit will inspire.
Block Kit builder allows you to add elements to blocks as well. Give it a try! Alternatively, read the Block Kit element reference guide for all the info you'll need for manually implementing individual elements.
Whether you need a complete web API to access a geospatial resource or just some bits to geo-enable your web application, the OGC building blocks could be a solution to provide standard, testable, interfaces, some of which with a high level of maturity. Let's not reinvent the wheel!
Did you ever have the need to define a bounding box parameter in your application? It is easy: you can just create an array of coordinates. But should you use the coordinates of the lower left and upper right corner, or upper left and lower right corner? What about the order - should it be x,y or lat,long ? And what happens with the crs?
Every day, developers around the world solve this same problem, in a slightly different way. And yet this is exactly what we want to avoid with the location building blocks - people solving the same problems, again and again - even if they solve them well, which is not always the case. The granular building blocks are used by the OGC APIs to address the requirements of these APIs, which are common requirements of location APIs; for instance: the need of a bounding box parameter or an extent data type. Next time you need to address a geo requirement in your application, instead of spending time thinking about a solution, check-out the existing location building blocks.
Whether you want to implement an API to access some kind of geospatial resource, or you want to spatially enable your API, you should check out the OGC building blocks. Even if you just need a small piece of functionality, the odds are this already exists. Adopting OGC building blocks also has the benefit of bringing interoperability into your application. On the other hand, if your application does not deal with geospatial data in any way, you probably do not need the OGC building blocks.
You actually do not need to use those. They were created to ensure consistency within OGC API's where there was not a clear mainstream standard. They aim to be in line with best practices of the web and could be replaced, e.g. by building blocks specified in an IETF RFC or similar, if and when they are available. Although API's built with the geo building blocks do not need to use these, they provide a nice default option that OGC-focused tools will understand.
You do not need any prior knowledge of OGC standards, in order to use the building blocks. They are completely standalone. If you are using geospatial data, depending on your use case you probably need to understand some concepts, like coordinate reference systems or bounding boxes, but that is about it.
The building blocks rely on the technologies and best practices used in the web, in general: use of standard http methods, use of http status codes, content negotiation, recommended YAML and JSON encodings, OpenAPI definition.
The OGC APIs are developed by their corresponding Standards Working Groups (SWG). When a SWG identifies something which has the potential to be used outside the original context of the OGC API, they incubate it as a granular building block.
Parts of OGC APIs which are published as approved standards, are expected to be stable. The most granular building blocks are published with an associated maturity level, which gives an idea of their stability.

The building blocks are developed through a member-driven consensus process, which creates royalty free, publicly available, open geospatial standards. The Open Geospatial Consortium (OGC) is the organization which drives this process. It is supported by an active community of members, with involvement from a large range of organizations, as well as smaller ones. Join OGC today!
Humans and all other living things have DNA, which contains hereditary information. The information in your DNA gives your cells instructions for producing proteins. Proteins drive important body functions, like digesting food, building cells, and moving your muscles.
DNA is arranged like two intertwined ropes, in a structure called a double helix (see figure 1). Each strand of DNA is made of four types of molecules, also called bases, attached to a sugar-phosphate backbone. The four bases are adenine (A), guanine (G), cytosine (C), and thymine (T). The bases pair in a specific way across the two strands of the helix: adenine pairs with thymine, and cytosine pairs with guanine.
Each chromosome can be identified by its size and shape under a microscope. Each has a specific set of genes that is the same from person to person. One copy of each chromosome in a pair is inherited from each parent, which means that you inherit one copy of each gene from your mother and one copy from your father.
Each chromosome has a centromere at its center, which is a small structure that divides the chromosomes into two parts (see figure 2). Each part is called an arm. Genes are located on the arms of the chromosomes.
Chromosomes have caps on each arm called telomeres, which help to protect the chromosomes. As you get older, your telomere caps get shorter and shorter and are less able to protect your chromosomes from getting damaged.
Genes are small segments of DNA that have different functions. Many, but not all, genes make the proteins that our bodies need to function. You have two copies of each gene, one on each chromosome in a pair.
Genes that code for proteins come in different versions called alleles. Alleles of a gene have differences in the precise DNA sequence. A common example of this is eye color. We each have the same genes for eye color, but different allele combinations within those genes result in different eye colors.
Traits are your observable characteristics. Many physical traits are genetic. Genetic differences give our bodies information that result in traits that differ from person to person. We can also use genetic information to determine what inherited traits you may have.
A difference from the expected sequence of a gene is called a variant or mutation. Variants can be inherited from your parents, or they can happen spontaneously. All of us have variants, but not all variants are harmful. Variants that are harmful can cause or increase our risk for certain diseases.

The machine learning community has primarily focused on developing powerful methods, such as feature visualization , attribution , and dimensionality reduction , for reasoning about neural networks. However, these techniques have been studied as isolated threads of research, and the corresponding work of reifying them has been neglected. On the other hand, the human-computer interaction community has begun to explore rich user interfaces for neural networks , but they have not yet engaged deeply with these abstractions. To the extent these abstractions have been used, it has been in fairly standard ways. As a result, we have been left with impoverished interfaces (e.g., saliency maps or correlating abstract neurons) that leave a lot of value on the table. Worse, many interpretability techniques have not been fully actualized into abstractions because there has not been pressure to make them generalizable or composable.
In this article, we treat existing interpretability methods as fundamental and composable building blocks for rich user interfaces. We find that these disparate techniques now come together in a unified grammar, fulfilling complementary roles in the resulting interfaces. Moreover, this grammar allows us to systematically explore the space of interpretability interfaces, enabling us to evaluate whether they meet particular goals. We will present interfaces that show what the network detects and explain how it develops its understanding, while keeping the amount of information human-scale. For example, we will see how a network looking at a labrador retriever detects floppy ears and how that influences its classification.
