데이터 교환 포맷에 있어 현재 JSON은 절대적 위치를 가지고 있지만, 업무에 따라선 다른 포맷을 사용해달라는 요구가 종종 있다.

데이터 크기를 줄이고자 하는 목적이 가장 크지만, 기존에 사용하던 언어 표현 (HTML, SQL, XML 등) 사이의 일부로 들어갔을 때 미적으로 좋은 편이 아니라는게 다른 포맷을 요구하는 이유이기도 하다.

이런 이유로 현장에서는 지속적으로 다양한 데이터 교환 포맷이 제안되어 왔다. 최근에는 AI 시대에 맞춰 TOON(Token-Oriented Object Notation)이라는 LLM에 최적화된 포맷이 나오면서 많은 주목을 받고있다.

과거, 나도 새로운 데이터 포맷을 만들라는 요구를 피해갈 수 없었던 사례가 있었다. 이렇게 만들어진 포맷으로 향후 누군가가 인터페이스 할 경우를 대비해 GitHub에도 어떤 표현 형식인지를 공유해두었다.

그 사례도 공유해보고자 한다.

중국이 일본을 정말 맛깔나게 뚜까패고 있는데, 이게 시진핑 집권 이후에 좀 공세적인 외교 성향으로 바뀐 그런 탓도 있긴 하지만, 지금 미국한테 계속 수세로 밀렸던 모양새다 보니 한번 정도 푸닥거리를 해서 체면을 좀 세우고 싶어 하던 그런게 있었을겁니다... 한국은 좀 체급이 약하기도 하지만 때려줄 만한 명분이 애매했던 차에, 일본이 대가리 쳐들고 뻣뻣하게 들이대니 너 잘걸렸다 하고 힘자랑을 하는 그런거 같죠. 마침 명분도 아주 좋게 하나의 중국을 정면으로 매도한 모양새가 되었으니.

Math Makers by Alfred S. Posamentier, 2020

The Lives and Works of 50 Famous Mathematicians

An entertaining history of mathematics as chronicled through fifty short biographies. Mathematics today is the fruit of centuries of brilliant insights by men and women whose personalities and life experiences were often as extraordinary as their mathematical achievements.





This entertaining history of mathematics chronicles those achievements through fifty short biographies that bring these great thinkers to life while making their contributions understandable to readers with little math background. Among the fascinating characters profiled are Isaac Newton (1642-1727), the founder of classical physics and infinitesimal calculus--he frequently quarreled with fellow scientists and was obsessed by alchemy and arcane Bible interpretation; Sophie Germain (1776 - 1831), who studied secretly at the Ecole Polytechnique in Paris, using the name of a previously enrolled male student--she is remembered for her work on Fermat's Last Theorem and on elasticity theory; Emmy Noether (1882 - 1935), whom Albert Einstein described as the most important woman in the history of mathematics--she made important contributions to abstract algebra and in physics she clarified the connection between conservation laws and symmetry; and Srinivasa Ramanujan (1887-1920), who came from humble origins in India and had almost no formal training, yet made substantial contributions to mathematical analysis, number theory, infinite series, and continued fractions.The unusual behavior and life circumstances of these and many other intriguing personalities make for fascinating reading and a highly enjoyable introduction to mathematics.

A People Betrayed by Paul Preston, 2019

A History of Corruption, Political Incompetence and Social Division in Modern

From the foremost historian of 20th century Spain, the story of the devastating betrayal of Spain by its political class, its military and its Church. This comprehensive history of modern Spain chronicles the fomenting of violent social division throughout the country by institutionalised corruption and startling political incompetence.



Most spectacularly during the Primo de Rivera and Franco dictatorships, grotesque and shameless corruption went hand-in-hand with inept policies that prolonged Spain's economic backwardness well into the 1950s. A People Betrayed looks back to the years prior to 1923 when electoral corruption excluded the masses from organized politics and gave them a choice between apathetic acceptance and violent revolution. Bitter social conflict, economic tensions and conflict between centralist nationalism and regional independence movements then exploded into the civil war of 1936-1939. It took the horrors of that war and the dictatorship...

Max the Miracle Dog by Kerry Irving, 2020

The Heart-Warming Tale of a Life-Saving Friendship

'Are you ready, Max? If anyone's going to help me do this, it's you.' The heart-warming tale of a life-saving friendship. In 2006, a traumatic car accident changed Kerry Irving's life forever. Suffering from severe neck and back injuries, Kerry was unemployed and housebound, struggling with depression and even thoughts of suicide.





He went from cycling over 600 miles a month to becoming a prisoner in his own home. With hope all but lost, Kerry's wife encouraged him to go on a short walk to the local shop. In the face of unbearable pain and overwhelming panic, he persevered and along the way, met an adorable yard dog named Max. As the Spaniel peered up through the railings, Kerry found comfort and encouragement in his soulful brown eyes. This chance encounter marked a turning point in both their lives. In Max, Kerry found comfort and motivation and in Kerry, Max found someone to care for him. This is their remarkable, inspiring story.

An American Genocide by Benjamin Madley, 2016

The United States and the California Indian Catastrophe
Between 1846 and 1873, California's Indian population plunged from perhaps 150,000 to 30,000. Benjamin Madley is the first historian to uncover the full extent of the slaughter, the involvement of state and federal officials, the taxpayer dollars that supported the violence, indigenous resistance, who did the killing, and why the killings ended.




This deeply researched book is a comprehensive and chilling history of an American genocide. 
Madley describes pre-contact California and precursors to the genocide before explaining how the Gold Rush stirred vigilante violence against California Indians. He narrates the rise of a state-sanctioned killing machine and the broad societal, judicial, and political support for genocide. Many participated: vigilantes, volunteer state militiamen, U.S. Army soldiers, U.S. congressmen, California governors, and others. The state and federal governments spent at least $1,700,000 on campaigns against California Indians.

Schools That Learn by Peter M. Senge, 2012

A Fifth Discipline Fieldbook for Educators, Parents, and Everyone Who Cares About Education

"A rich, much-needed remedy for the standardized institutions that comprise too much of our school system today... ideal for teachers and parents intent on resurrecting and fostering students' inherent drive to learn...An essential resource."
-Daniel H. Pink, author of DRIVE and A WHOLE NEW MIND





"Schools that Learn is a magnificent, grand book that pays equal attention to the small and the big picture - and what's more integrates them. There is no book on education change that comes close to Senge et al's sweeping and detailed treatment. Classroom, school, community, systems, citizenry---it's all there. The core message is stirring: what if we viewed schools as a means of shifting society for the better!"
-Michael Fullan, author of Change Leader and Learning Places

A new edition of the groundbreaking book that brings organizational learning and systems thinking into classrooms and schools...

Ethics for the Very Young by Erik Kenyon, 2019

A Philosophy Curriculum for Early Childhood Education
Can you be brave if you’re afraid? Why do we “know better” and do things anyway? What makes a family? Philosophers have wrestled with such questions for centuries. They are also the stuff of playground debates. Ethics for the Very Young uses the perplexities of young children’s lives to spark philosophical dialogue.






Its lessons scaffold discussion through executive function games (Telephone, Red Light Green Light), dialogic reading of picture books and Reggio Emilia’s art-based inquiry. In the process, children develop skills of dialogue and critical thinking through increased selective attention, self-control, cognitive flexibility and perspective taking. While the elements of this method are familiar, they are here fused into an organic whole grounded in the history of philosophy and defended by current work in developmental psychology. Building on Wartenberg’s Big Ideas for Little Kids, the present curriculum uses a series of 23 picture books to frame discussions of character, bravery, self-control, friendship, the greater good, respect and care. Its goal is not to “teach morals” but to help children articulate and develop their own perspectives through dialogue with each other. Each lesson presents teachers’ reflections on how this exploration of life's enduring questions transformed their school’s culture.

The Myth of the Nuclear Revolution by Keir A. Lieber & Daryl G. Press, 2020

Power Politics in the Atomic Age
Leading analysts have predicted for decades that nuclear weapons would help pacify international politics. The core notion is that countries protected by these fearsome weapons can stop competing so intensely with their adversaries: they can end their arms races, scale back their alliances, and stop jockeying for strategic territory.




 But rarely have theory and practice been so opposed. Why do international relations in the nuclear age remain so competitive? Indeed, why are today's major geopolitical rivalries intensifying? 
In The Myth of the Nuclear Revolution, Keir A. Lieber and Daryl G. Press tackle the central puzzle of the nuclear age: the persistence of intense geopolitical competition in the shadow of nuclear weapons. They explain why the Cold War superpowers raced so feverishly against each other; why the creation of "mutual assured destruction" does not ensure peace; and why the rapid technological changes of the 21st century will weaken deterrence in critical hotspots around the world. 
By explaining how the nuclear revolution falls short, Lieber and Press discover answers to the most pressing questions about deterrence in the coming decades: how much capability is required for a reliable nuclear deterrent, how conventional conflicts may become nuclear wars, and how great care is required now to prevent new technology from ushering in an age of nuclear instability.

The Poppy: a Cultural History from Ancient Egypt to Flanders Fields to Afghanistan by Nicholas J. Saunders, 2013

This is a story spanning three thousand years, from the ancient Egyptian fights over prized medicinal potions to the addicted veterans returning home from the American Civil War, from the British political machinations during the Opium Wars with China to the struggle to end Afghanistan's tribal narcotics trade.





Nicholas J. Saunders brings us the definitive history of this ever-enduring but humble flower of the fields.
In the aftermath of the horrific trench warfare of the First World War, the poppy – sprouting across the killing fields of France and Belgium, then immortalised in John McCrae's moving poem – became a worldwide icon. Yet the poppy has a longer history, as the tell-tale sign of human cultivation of the land, of the ravages of war and of the desire to escape the earthly realm through inspired Romantic opium dreams or the grim reality of morphine drips.

“Modern models can write and adapt exploit code, sift through huge volumes of stolen data, and orchestrate tools faster and more cheaply than human teams.”

“They lower the skills barrier for entry and increase the scale at which well-resourced actors can operate. We are effectively putting a junior cyber-operations team in the cloud, rentable by the hour.”

30-Second Evolution by Mark Fellowes, 2015

Adapt or die: it's nature's most famous imperative. But how does evolution actually happen? It's too slow to see, but it's going on all around you, all the time. Even if you're on top of the key terms - variation? Natural selection? Parent-offspring conflict? - you still need some context to put them in. From populations to speciation and polymorphism to evolutionary psychology, here's the one-stop source for all you need to know.


Evolution unlocks the laboratory of life, dissecting it into the 50 most significant topics that provide the missing links to understand the natural world's four-billion-year ancestry and the process of natural selection in which species either adapt in myriad ways - mutation, ingenuity, and intelligence - to meet the challenges of a changing environment, or die. Unravel the development of living organisms, at micro and macro level - from genes to geniuses.
